A grain dryer is the single piece of equipment most Canadian prairie farmers debate longest before buying. The reasoning is simple: it’s expensive, you only run it a few weeks a year, and a wrong choice means either burning canola seed at 50°C, watching wheat spoil because the unit can’t keep up with combine output, or paying for capacity you’ll never use. The Super-B name has been part of that decision for nearly five decades — long enough that “Super-B” is sometimes used by old-timers as a generic term for “grain dryer,” the way Kleenex is used for tissues. There’s a reason for that staying power, and a reason the modern SQ Series is still one of the most-installed continuous-flow dryers on the prairies.
This guide covers what Super-B grain dryers actually are in 2026, how the current SQ Series lineup is configured, what each model can realistically do for Canadian crops (canola, hard red spring wheat, durum, oats, peas, soybeans, corn), how to size a dryer for your operation, what older AS-series machines on the used market are worth, and the operational details that determine whether your dryer pays for itself in five years or sits as an expensive monument to a bad spec decision.
If you’re a first-time buyer trying to understand the category, a farmer comparing Super-B to GSI, Vertec, or Neco, or someone weighing a used 1987 AS600G against a new SQ16, this guide is written for you.
The Super-B Story: From Humboldt to Brock
The Super-B name was born on the prairies. Originally manufactured in Humboldt, Saskatchewan, the first Super-B continuous-flow grain dryers were sold to Canadian farmers in the early 1980s. Government testing reports from the era — including PAMI evaluations of the Super-B AS-600G and the S500C — document machines designed specifically for the moisture realities of prairie wheat, barley, and rapeseed (now canola), not the corn-belt operations that drove most of the dryer industry.
That prairie pedigree mattered. American dryer designs of the period were optimized for one job: pulling 25.5% corn down to 15.5%. Super-B engineers built machines that handled that as well as anyone — but also handled tough 16% wheat, damp canola at 12%, and the small-grain conditions where seed size demanded different screens, different metering, and different temperature management.
In the years since, Super-B was acquired by Brock Grain Systems, a major US-based grain handling and storage manufacturer. Today the line is officially the Super-B Energy Miser SQ Series sold under the Brock umbrella. The brand survived the acquisition because it earned its reputation — but the modern equipment carries the engineering depth of one of North America’s largest grain-equipment companies.
For Canadian buyers, the practical implication is simple: the Super-B name still represents what it always did — well-engineered continuous-flow drying built for prairie conditions — but the parts network, dealer support, controls technology (the INTUI-DRY touchscreen and remote monitoring system), and unloading systems (the EVENFLO drag conveyor) reflect Brock’s significant ongoing investment in the platform.
The Current Super-B SQ Series Lineup
The SQ Series spans nine model sizes, from the SQ8 (smallest, ~250 wet bushels per hour) to the SQ40 (largest, ~1,900 wet bushels per hour). Here are the headline specs for the lineup:
| Model | Total Fan HP | Auger Load HP | Chain Unload HP | Column Length | Overall Length | Holding (Bu) |
|---|---|---|---|---|---|---|
| SQ8 | 10 | 2 | 2 | 8′ 2″ | 19′ 0″ | 163 |
| SQ12 | 10 | 3 | 2 | 12′ 3″ | 23′ 1″ | 245 |
| SQ16 | 15 | 3 | 2 | 16′ 4″ | 27′ 2″ | 326 |
| SQ20 | 20 | 5 | 2 | 20′ 5″ | 31′ 3″ | 408 |
| SQ24 | 25 | 5 | 2 | 24′ 6″ | 36′ 4″ | 490 |
| SQ28 | 30 | 7.5 | 2 | 28′ 7″ | 40′ 5″ | 572 |
| SQ32 | 40 | 7.5 | 2 | 32′ 8″ | 44′ 6″ | 654 |
| SQ36 | 50 | 10 | 2 | 36′ 9″ | 48′ 7″ | 734 |
| SQ40 | 50 | 10 | 2 | 40′ 10″ | 52′ 8″ | 815 |
All models share an overall height of 14′ 2″. Most prairie farms operating one or two combines fall in the SQ12 to SQ24 range; large commercial operations and pulse processors typically size up to SQ28 or larger.
Drying Capacity by Crop and Mode
Capacity depends on the crop, the moisture removal target, and the drying mode you select. These are the manufacturer’s published rated capacities for the most-common reference (corn, 25.5% to 15.5%, full heat single zone Model D):
| Model | Corn 25.5→15.5% (Bu/h) | Corn 20.5→15.5% (Bu/h) |
|---|---|---|
| SQ8 | 248 | 405 |
| SQ12 | 351 | 579 |
| SQ16 | 466 | 770 |
| SQ20 | 591 | 976 |
| SQ24 | 740 | 1,211 |
| SQ28 | 830 | 1,371 |
| SQ32 | 969 | 1,601 |
| SQ36 | 1,066 | 1,761 |
| SQ40 | 1,153 | 1,905 |
For prairie crops, the math changes — sometimes dramatically. As a rule of thumb, hard red spring wheat at typical tough-to-dry moisture levels (16% down to 14.5%) dries roughly 30–40% faster than corn at the same model rating because there’s much less water to remove. Canola dries faster still per bushel, but you’re constrained by lower allowable temperatures (45°C maximum for seed-grade canola, 82°C maximum for canola going to crush). Always confirm crop-specific capacity with your dealer before sizing — the corn ratings above are useful for cross-model comparison, not for predicting your wheat throughput.
Configuration Codes: A, E, D, M — What Each Suffix Means
When you see a Super-B model designation like “SQ16E” or “SQ24A,” the letter after the size matters as much as the size itself. It tells you what drying modes the unit supports.
- D – Full Heat (Single Zone) — continuous flow drying using one temperature throughout. Simplest configuration, lowest cost, used for grains that don’t require staged drying. Available SQ8 through SQ40.
- E – Continuous Flow with Louvers — supports full heat, pressure heat / pressure cool, or pressure heat / vacuum cool drying. The most flexible standard configuration for prairie operators handling multiple crops.
- A – Continuous Flow with Hot Air Return Duct — same modes as E, but adds a hot air return duct that recovers exhaust heat for reuse. The fuel-efficiency premium model — saves up to 20% on fuel costs in continuous operation. Higher capital cost but pays back fast on heavy-use operations.
- M – Two-Temperature-Zone — capable of either full heat or pressure heat / pressure cool drying using two distinct temperature zones. Useful for sensitive crops where you want a hotter top zone for moisture removal and a cooler bottom zone to protect the grain.
For most Canadian prairie buyers handling wheat, canola, oats, and peas, the E configuration offers the best flexibility-to-cost ratio. If you’re running 1,500+ hours per drying season, the A configuration’s energy savings start paying back within a few years. The M configuration appeals most to seed-grade producers and pulse processors who need the temperature control. The D configuration is appropriate for simple feed-grade operations focused on a single crop.
How Super-B Drying Technology Actually Works
Strip away the marketing and a Super-B SQ Series dryer does four jobs sequentially:
1. Wet garner pre-heating. Wet grain enters a perforated wet garner bin at the top of the unit. Heated exhaust air from the lower drying chambers is routed through this garner, pre-warming and partially drying the grain before it ever reaches the main drying column. This is one of the meaningful innovations — competitors with simple holding bins lose this pre-heating opportunity.
2. Variable-width column drying. The grain column itself is narrower at the top and wider at the bottom. This sounds like a small detail; it’s actually the central technical idea of the SQ Series. Moisture-saturated air escapes more readily from a narrower column, so the wettest grain (top of the column) dries through a column geometry optimized for moisture removal. As grain moves down, it transitions to a wider, lower-velocity zone better suited for finishing and cooling. Compare this to fixed-width competitors that compromise either drying rate or cooling efficiency.
3. Heated air through the grain mass. Brock’s full flame-wall burner with stainless steel baffles distributes heat evenly across the grain columns using a shorter, cleaner flame than older perforated-tube designs. The plenum geometry is designed to deliver uniform temperatures at every point along the column — meaning the grain in the middle of the column dries at the same rate as the grain near the walls, which is what reduces over-drying and protein/oil damage.
4. Cooling and discharge. Depending on configuration, the unit can run pure full-heat (cooling happens in the storage bin afterward), pressure heat / pressure cool (cooling air pushed through the lower column), or pressure heat / vacuum cool (cooling air pulled through the lower column). The EVENFLO drag-chain unloading system replaces the metering rolls and augers found on most competitors. The advantage: gentler grain handling (less kernel damage), the ability to pass debris that would jam an auger, and easier cleaning between crops with a removable top cover.
The double-width, double-inlet centrifugal blower is standard equipment and provides the “Super Quiet” aspect of the SQ name. Compared to the axial fans on older Super-B models and many competitors, the centrifugal design produces materially less noise — operators report being able to hold a normal conversation immediately beside the unit. The trade-off, well-known to long-time Super-B operators, is that centrifugal fans can ice up in extreme cold (below about –17°C); axial fans handle cold-weather drying with fewer interruptions. For most prairie harvests this isn’t a daily problem, but late-October drying in northern Alberta or northern Saskatchewan occasionally requires a thaw-out cycle.
The modern controls are the INTUI-DRY touchscreen system (15.6-inch display) with remote smartphone access — meaning you can monitor and adjust the dryer from your phone while running the combine. For multi-bin operations, this is a significant labor-saver during peak harvest pressure.
Sizing Your Super-B: The Math Most Buyers Get Wrong
The most expensive sizing mistake on the prairies is buying a dryer that can’t keep up with combine output. The second most expensive is buying one too large for what your wallet and bin yard actually justify. Here’s the practical math.
Step 1: Calculate your real combine output
Combine manufacturers publish theoretical bushels-per-hour ratings under ideal conditions. Real-world output is typically 50–70% of rated. A modern Class 8 combine rated at 5,000 bushels/hour realistically averages 2,500–3,500 bu/hr in prairie conditions over a full day, factoring in transport time, unloading delays, slugs, and headland turns.
Step 2: Calculate your moisture removal requirement
If your wheat is coming off at 16% and target is 14.5%, you’re removing 1.5 percentage points. If your canola is coming off at 12% and target is 8%, you’re removing 4 points. The energy and time required scale with the moisture removal — not with bushels alone.
Step 3: Apply the dryer’s published capacity for your specific scenario
Manufacturer ratings are typically published for corn 25.5%→15.5% (10 points) or 20.5%→15.5% (5 points). For other crops and other moisture differentials, the math changes. As a rough approximation:
- Wheat 16%→14.5% (1.5 points): ~3-4× the published corn 5-point capacity in bushels of throughput
- Canola 12%→8% (4 points): roughly 1.2-1.5× the published corn 5-point capacity, but constrained by maximum allowable seed temperature (45°C for seed grade, 82°C for crush grade)
- Oats 16%→14% (2 points): ~2.5-3× corn 5-point capacity
- Peas 18%→16% (2 points): ~2× corn 5-point capacity, with care to avoid splitting
These are starting points for conversation with your dealer, not precise quotes — actual capacity varies with grain temperature, ambient temperature, fines content, and crop maturity.
Step 4: Match dryer capacity to combine output
A common rule among prairie operators: the dryer should match or slightly exceed combine output for your most-demanding crop scenario. If your worst case is two combines running on tough canola at 12%, you need a dryer that can dry that combined output without backing up. If you’re undersized, the combines have to slow down or stop, and your harvest window — already short on the prairies — gets shorter.
Practical sizing examples
These are rough guides, not gospel. Adjust for your specific crop mix, moisture history, and combine output.
- Quarter-section to half-section grain operation (single combine): SQ8 to SQ12. Most operators in this category run an SQ12 for the headroom on tough years.
- Section-and-a-half to two-section operation (single large combine): SQ16 to SQ20. The SQ16 is the most-installed model in this segment.
- Two-combine prairie operation: SQ24 to SQ28. SQ24 is the prairie sweet spot for most two-combine setups.
- Three-combine large commercial operation: SQ28 to SQ32.
- Pulse processors, seed plants, custom drying operations: SQ32 to SQ40.
Drying Prairie Crops: Crop-by-Crop Considerations
This is where Super-B’s prairie heritage shows up. Each major prairie crop has its own drying personality.
Hard Red Spring Wheat (and Durum)
Wheat is the most forgiving crop a prairie dryer ever sees. Maximum recommended drying temperatures — for milling-grade wheat, generally 65°C to 80°C plenum temperature — are well within what any SQ Series unit produces. The Canadian Grain Commission’s drying guidelines call for removing no more than 6 percentage points of moisture in one pass through a high-speed dryer, and for very wet wheat (over 20%), running two passes at moderate temperatures is preferable to one aggressive pass.
The risk is invisible: excessive heat can damage gluten protein in milling wheat. The damage is real but visually identical to undamaged kernels. Bakers can detect the difference; you cannot. The lesson: don’t push temperatures higher than necessary on milling-grade wheat just because the dryer is capable.
Canola
Canola is the crop where dryer choice and operation matter most. Canola Council of Canada guidelines:
- Seed-grade canola (going to next year’s crop): maximum 45°C grain temperature
- Crush-grade canola (going to oil extraction): maximum 82°C grain temperature
- For very damp canola (above 12%): prefer two passes at lower temperatures over one aggressive pass
The reason for the seed-grade limit is biological — heat above 45°C reduces germination viability. The reason for the crush-grade limit is chemical — excessive heat denatures the oil, reducing quality and value. Continuous-flow dryers like the Super-B SQ Series are preferable to batch dryers for canola because the grain spends less time at peak temperature, reducing both seed damage and fire risk.
The “fire risk” point is not theoretical. Canola is oilseed; trapped fines combined with hot surfaces have caused dryer fires on the prairies more than once. Daily inspection and cleaning of screens, especially around any change of crop, is non-negotiable. Super-B’s removable top cover on the EVENFLO unloading system makes between-crop cleaning materially easier than on auger-based competitors.
Oats
Oats handle drying well — the main concern is preserving milling quality (whole groats, no cracked or damaged kernels). The variable-width column geometry of the SQ Series is well-suited to oats because it minimizes mechanical handling damage. Drying temperatures of 60–70°C are typical.
Peas (Yellow and Green)
Peas are the most physically delicate prairie crop. Splitting and skin damage downgrade pulse-quality peas dramatically. The EVENFLO drag-chain unloading system is a meaningful advantage for pea drying compared to metering-roll competitors — gentler grain flow translates directly to better grade-out at the elevator. Drying temperatures should be moderate (50–65°C) and moisture removal limited to 2–3 percentage points per pass for premium pulse-grade.
Soybeans
Soybeans are increasingly grown across southern Manitoba, southwestern Ontario, and eastern Saskatchewan. Drying soybeans below 13% moisture causes significant kernel damage and quality loss; the target is typically 13.5–14%. Maximum recommended grain temperature is 50–55°C for seed-grade soybeans, slightly higher for commercial grade.
Corn
In the Canadian context, corn drying is mainly a southern Manitoba and Ontario concern — but it’s the design baseline of every continuous-flow dryer manual ever written. SQ Series dryers handle corn excellently across the full range from high-moisture (25%+) to slightly tough (17%+). Maximum plenum temperatures up to 110°C are appropriate for feed-grade corn; lower for seed corn.
Fuel Choice: Natural Gas vs. Propane
Every Super-B SQ Series dryer can be specified for either natural gas or liquid propane. The right choice depends almost entirely on what’s available at your yard.
Natural gas advantages:
- Significantly lower fuel cost per BTU at most prairie locations
- No tank refills during harvest peak
- Cleaner combustion, less burner maintenance over time
Natural gas disadvantages:
- Requires utility connection (often $5,000–25,000+ to bring service to your yard if not already present)
- Locked-in to one supplier and tariff structure
- Some rural locations simply don’t have natural gas service available
Propane advantages:
- Available anywhere in Canada
- Faster to commission a new dryer installation
- Tank ownership or lease is straightforward
- More portable if you might move the dryer in future
Propane disadvantages:
- Higher fuel cost per BTU (often 30–60% more than natural gas)
- Requires tank infrastructure and refill logistics during peak harvest
- Cold-weather propane can be sluggish — bulk tanks need to be sized to maintain vapor pressure
If natural gas is available at your yard for under $25,000 connection cost, the long-term math almost always favors natural gas for any operation drying more than ~50,000 bushels per season. If you’re running smaller volumes, drying intermittently, or natural gas requires a major utility extension, propane is the practical choice.
New vs. Used Super-B: What You Should Pay
Super-B has been in the market for over four decades, which means there’s a substantial used market — particularly in Saskatchewan, Manitoba, and Alberta where many of the early units were sold and many are still operating.
Pricing benchmarks (Canadian market, 2026)
New Super-B SQ Series (with installation):
- SQ8: ~$110,000–140,000 CAD
- SQ12: ~$140,000–180,000 CAD
- SQ16: ~$180,000–230,000 CAD
- SQ20: ~$220,000–280,000 CAD
- SQ24: ~$260,000–340,000 CAD
- SQ28: ~$310,000–410,000 CAD
- SQ32 and up: $375,000+ CAD
These ranges include site preparation, electrical work, fuel connection, and basic ancillary equipment. Stand-alone unit prices are typically 30–40% lower; full integrated installations with elevator legs, wet bins, and pneumatic distribution systems run substantially higher.
Used Super-B (current Canadian market):
- 1980s–1990s AS-series (AS300G, AS600G, AS800G): $5,000–25,000 CAD depending on condition. These are the original Humboldt-built units. Many still run reliably, but parts can be challenging on the oldest models. Best value in the SQ300G to SQ600G size range for small operations.
- 2000s SQ300B, SQ500B (older SQ generation, axial fan): $30,000–80,000 CAD. Reliable workhorses still common at prairie auctions.
- 2010s SQ8–SQ24 (modern centrifugal-fan generation): $90,000–225,000 CAD depending on hours, condition, and configuration.
What to inspect on a used Super-B
Beyond the general grain dryer inspection points, watch for these Super-B specifics:
- Stainless steel perforated skins: check for corrosion patches, especially near the bottom of the column where moisture exposure is highest. Stainless skins are one of Super-B’s signature features and one of the more expensive components to replace if damaged.
- Burner condition: the full flame-wall burner with stainless baffles is well-built but accumulates carbon and corrosion over years of use. Have it inspected and tested.
- Centrifugal blower bearings: failure mode is typically progressive bearing noise, then catastrophic failure. Listen during operation. Replacement is moderate cost, but downtime during harvest is the real cost.
- EVENFLO drag chain: check for stretch and damaged paddles. Take-up adjustment ranges should still have travel remaining; if the chain has been adjusted to the limit, replacement is imminent.
- Plenum door safety switch: required for safe operation. Verify the switch shuts down the dryer when the door is opened. Bypassed safety switches are a red flag and a fire risk.
- Controls generation: older mechanical controls (rotary burner valves, analog gauges) work fine but are getting harder to find replacement parts for. Mid-2010s machines with the QUANTUM or SPECTRUM controllers, or current INTUI-DRY units, command meaningful price premiums for good reason.
- Hour meter and service history: ask for service records. A well-maintained dryer at 5,000 hours can be a better buy than a neglected one at 1,500.
Where used Super-B equipment is sold in Canada
The largest used Super-B inventory typically comes through:
- Major equipment auctions — Ritchie Bros., Allen B. Olson (Alberta), Fraser Auctions (Manitoba/Saskatchewan)
- Specialty dealers — GlenMor Equipment (Prince Albert, SK), Rosler Construction (Saskatoon, SK), Valley Agro Services, Flaman Agriculture
- Online marketplaces — AgDealer, MarketBook, Kijiji (be cautious on Kijiji — verify seller and inspect in person)

Super-B vs. GSI vs. Vertec vs. Neco: Honest Comparison
Super-B is one of four major continuous-flow dryer brands sold across Canadian prairies. Here’s how they actually compare.
Super-B (Brock SQ Series) — best at: prairie crop versatility, quiet operation (centrifugal blower), gentle grain handling (EVENFLO drag chain), modern controls (INTUI-DRY). Best for: mixed-crop prairie operations valuing fuel efficiency and grain quality.
GSI (Grain Systems Inc.) — best at: very large capacity (Tower Dryer line goes well above 4,000 bu/hr), strong dealer network in Canada, broad parts availability. Models like the GSI 1112 and 1226 are common at prairie auctions. Best for: large commercial operations and elevators.
Vertec — best at: simple reliable batch and continuous-flow drying with tower dryer designs. Lower-capital alternative to GSI in similar size classes.
Neco — best at: heavy-duty stack designs (the 16140 and 16120 are workhorses), strong cold-weather performance, simple mechanical controls. Best for: operators who prioritize repairability over electronics and heavy crop volumes.
Farm Fan — best at: smaller capacities, legacy units still operating across the prairies. Common in the used market. Best for: smaller operations or as a backup unit.
The fair summary: for a prairie buyer choosing between new units in the 250–1,500 bu/hr range, Super-B SQ Series, GSI Tower Dryer, and Neco are the three most-installed options. Super-B leads on grain quality and operator comfort. GSI leads on raw capacity and dealer reach. Neco leads on cold-weather operation and simplicity. The right answer depends on your specific crop mix, harvest moisture history, and the dealers near your operation.
Installation and Operating Costs You Need to Plan For
A Super-B dryer doesn’t operate in isolation — it requires infrastructure. Common items buyers underestimate:
Concrete pad. A SQ16-class dryer needs a properly engineered reinforced concrete pad. Budget $8,000–15,000 for the pad alone, depending on local soil conditions and contractor pricing.
Electrical service. Three-phase power is strongly preferred. Single-phase 220V works on smaller models but limits capacity. If your yard doesn’t have three-phase service, factor in $15,000–50,000+ for utility upgrades.
Wet bin / wet hopper. A dryer is only as productive as the wet grain feeding it. Plan for a wet bin sized to hold at least 4 hours of combine output — typically 1,000–3,000 bushels for prairie operations. Add $20,000–60,000 if you don’t already have suitable wet storage.
Discharge handling. Dried grain has to go somewhere. Pneumatic systems (Walinga, etc.) are popular with Super-B installations because they eliminate the dust and labor of auger handling — but a full Walinga Ultra-Veyor system runs $40,000–100,000+ depending on distance and number of bins.
Fuel infrastructure. Either propane tank installation ($5,000–20,000 depending on tank size and configuration) or natural gas connection ($5,000–25,000+ depending on distance from existing service).
Catwalks, ladders, and safety equipment. Required by Canadian provincial workplace safety regulations. Budget $5,000–15,000 depending on dryer size.
Operating costs (per drying season):
- Fuel: highly variable, but 0.015–0.025 BTU per pound of water removed is a typical efficiency benchmark. For a prairie operation drying 30,000 bushels of canola from 12% to 8%, expect roughly $4,000–8,000 in fuel cost depending on natural gas vs. propane.
- Electricity: $500–2,000 per season depending on hours of operation and provincial rates.
- Maintenance and parts: budget 1–2% of new replacement cost annually.
- Service contracts (recommended for operations above SQ20): $1,000–3,000 annually.
Common Questions Canadian Farmers Ask Before Buying a Super-B
Is Super-B still a Canadian brand?
The Super-B name and product line originated in Humboldt, Saskatchewan in the early 1980s. The brand is now owned by Brock Grain Systems, a US-based company that is part of CTB Inc. The product is still sold under the Super-B Energy Miser SQ Series name and remains heavily installed across the Canadian prairies through the existing Canadian dealer network. The engineering philosophy that made Super-B suitable for prairie crops has been retained and developed by Brock.
What size Super-B do I need for my farm?
The honest answer requires more conversation than a guide can provide. The starting framework: match dryer capacity to your combined combine output for your most-demanding crop scenario (typically tough canola or wet wheat). For a single Class 8 combine harvesting on the prairies, an SQ12 to SQ16 is the typical sweet spot. For two combines, an SQ20 to SQ24. Have a sizing conversation with two or three dealers before committing — and ask each one to show their math.
Can I run a Super-B in extreme cold?
The centrifugal blowers on modern SQ Series units can ice up below approximately –17°C, requiring a thaw cycle before resuming operation. For most prairie harvests this is not a daily issue — but late-October or early-November operation in northern Alberta and Saskatchewan can occasionally require interrupting drying to thaw the fan. Older Super-B models with axial fans are less affected by this. Plan your harvest timeline accordingly.
How long does a Super-B grain dryer last?
With proper maintenance and reasonable annual hours, current SQ Series units are designed for a 25–30+ year service life — and there are AS-series Super-Bs from the 1980s still operating across the prairies in 2026. Stainless steel perforated skins, the most expensive structural component, typically outlast the rest of the machine if kept reasonably clean. Burners and blowers are serviceable indefinitely with parts replacement.
What’s the most expensive component to fail?
Major repairs in order of cost:
- Burner replacement: $8,000–20,000 depending on model
- Centrifugal blower assembly: $5,000–15,000 with motor
- Drive system and EVENFLO chain: $3,000–8,000
- Stainless skin replacement: $5,000–25,000+ (rare; usually only after corrosion neglect)
- Controls upgrade (older unit to modern INTUI-DRY): $8,000–20,000
Routine maintenance — bearings, belts, sensors, screens — typically runs $500–2,000 per year on a well-maintained unit.
Is the SQ Series energy efficient enough to justify the price over older designs?
The “Energy Miser” branding refers to the recovered-heat hot air return duct on A-configured units, which can save up to 20% in fuel cost compared to non-recovery designs. For operations drying high volumes (50,000+ bushels per season), the fuel savings on an A configuration typically pay back the configuration premium within 3–5 years. For lower-volume seasonal users, an E configuration is more economical. The variable-width column geometry, regardless of configuration, also delivers measurable efficiency improvements over older fixed-width designs.
Can I buy a Super-B factory-direct or do I need a dealer?
Super-B SQ Series dryers are sold through authorized Brock dealers across Canada. Major prairie dealers include Rosler Construction (Saskatoon, SK), Valley Agro Services, Agri-Systems Inc., and several others. Direct-from-factory purchasing isn’t available for most buyers. The dealer relationship matters because installation, commissioning, and ongoing service are integral to the product — buying a dryer without strong local dealer support is one of the most expensive false-economy decisions in this category.
Should I buy used or new?
The case for used: 50–70% capital cost savings on equivalent capacity. The case for new: factory warranty (typically 5+ years on major components), modern controls (INTUI-DRY remote monitoring), latest emissions and safety standards, and confidence in installation quality. For first-time buyers without strong mechanical infrastructure, new is generally the lower-risk choice. For experienced operators with their own service capability and tolerance for occasional downtime, well-inspected used Super-B units often deliver excellent value.
What financing is available?
Most Canadian agricultural lenders — Farm Credit Canada, ATB Financial, the prairie credit union network, and the major banks — offer equipment financing on grain dryer purchases, often with terms structured to align with crop revenue cycles (e.g., principal payments timed to grain delivery). Brock and most major dealers also have manufacturer-supported financing programs. Lease-to-own arrangements are increasingly common for higher-end installations. As with any major capital purchase, get pre-approved before negotiating equipment pricing — a documented financing position is leverage at the dealer table.

Final Word: The Dryer Decision Is Bigger Than the Dryer
The Super-B in your yard isn’t really a piece of equipment — it’s a strategy decision about how you handle harvest weather risk, grade premiums, and labor over the next two decades.
Buyers who undersize regret it the first wet harvest. Buyers who oversize regret it every quarter when the loan payment doesn’t match the bushels dried. Buyers who skip the infrastructure (wet bin, three-phase power, pneumatic discharge) regret it the second day of running. Buyers who choose a brand based purely on hammer price, without weighing dealer support, regret it the first time something breaks at 11 PM during a 24-hour push.
Super-B has earned its place on prairie farms because it does what it claims and the dealer network behind it actually shows up. That’s not the same as saying it’s the right choice for every farm. But for most prairie buyers handling mixed crops — wheat, canola, oats, peas — and operating in the SQ12 to SQ24 size range, the Super-B SQ Series is on the short list for legitimate reasons.
Talk to two dealers minimum. Ask both for sizing math you can verify. Ask both for references at farms within 100 km of yours. Visit those farms, talk to those operators, watch a dryer running. Then decide.
Good drying.
