GSI 2326 & 2326X Portable Grain Dryer

The GSI 2326 is the flagship two-module portable grain dryer in the 2300 Series, built around three vane axial fans (one upper, two lower), three high-output heaters, and a three-stage drying architecture. With 1,304 bushels of holding capacity and Full Heat drying performance up to 2,700 BPH at 5-point moisture removal, the 2326 delivers the maximum throughput possible from any GSI two-module portable dryer with the standard 1+2 fan configuration. For operations needing more capacity than this, the next steps are the four-fan 2400 Series or the three-module 3400 Series.

The 2326 is offered in two configurations: standard and X-Stream optimized 2326X. Both share identical drying performance, fans, heaters, and grain column — the difference is the fan layout, with X-Stream delivering measurably better grain uniformity at the same throughput.

The 2326 represents a major engineering step up from every other 2300 Series model. The 26-foot grain column requires substantially larger fans and heaters across both modules, which directly translates to higher electrical infrastructure requirements, greater fuel consumption per hour, and significantly higher capital cost. In return, the 2326 delivers Full Heat capacity that approaches the lower end of three-module 3400 Series performance — making it the right choice for large operations where two-module simplicity is preferred over three-module installations.

For operations handling 10,000 to 15,000+ acres of corn — or any grain operation needing reliable Full Heat throughput in the 2,400–2,800 BPH range — the 2326 frequently represents the most cost-effective single-purchase solution before stepping into the much larger physical and capital footprint of a 3400 Series three-module dryer.

2326 vs 2326X — Configuration Choice

The 2326 is offered in two configurations. Both share identical drying performance, fans, heaters, and grain column. The difference is the fan layout.

2326 — Standard Configuration

The standard 2326 uses GSI’s conventional three-fan layout for the 2300 Series — one fan and heater on the upper module, two fans and heaters on the lower module. This delivers the full 2,700 BPH Full Heat capacity at 5-point removal with standard heat distribution across the grain column.

Best for: Large operations primarily running Continuous Dry & Cool or All Heat where grain uniformity isn’t a premium grading factor. High-volume general-purpose corn drying applications fit this profile.

2326X — X-Stream Variant

The 2326X is a 2326 with the X-Stream fan rearrangement applied. X-Stream redistributes airflow and heat across the grain column from front to back, producing measurably more uniform drying. Capacity numbers stay identical to the standard 2326 (2,700 BPH Full Heat at 5-point removal), but grain quality at that throughput improves — fewer overdried kernels at hot spots and fewer wet pockets at cooler areas in the column.

X-Stream is particularly valuable on the 2326 because the longer 26-foot grain column has the greatest potential for front-to-back heat variation in the entire 2300 Series. The X-Stream layout effectively neutralizes that variation, which becomes critical at the 2326’s high throughput level where uneven drying losses scale with volume.

Best for: Large-scale food-grade corn producers, high-volume seed corn operations, large malting barley growers (with small grain screen), and any operation where grain uniformity directly affects grading and price at scale. On a unit handling 200,000+ bushels per harvest season, even small uniformity gains translate to substantial dollar value at the elevator.

There’s no S/H distinction within the 2300 Series. The 2326X is simply the 2326 with X-Stream applied at order, and both configurations share the same structural specifications.

Drying Capacity

All capacities below are wet bushels per hour, based on mature unfrozen #2 yellow shelled dent corn. Full Heat assumes grain is cooled in-bin after discharge; Dry & Cool numbers reflect grain that exits the dryer already cooled. The 2326 and 2326X share identical capacity ratings.

Mode	Moisture Removal	Capacity
Full Heat	30% to 15%	1,200 BPH
Full Heat	25% to 15%	1,670 BPH
Full Heat	20% to 15%	2,700 BPH
Dry & Cool	25% to 15%	1,130 BPH
Dry & Cool	20% to 15%	1,840 BPH

The 2326 hits 2,700 BPH in Full Heat at 5-point removal — about 23% more than the 2322 and the highest two-module Full Heat capacity in the entire GSI portable dryer lineup. The capacity gain over the 2322 is delivered by simultaneous upgrades across the entire dryer: column extends from 22′ to 26′, the top fan jumps from 30 HP/42″ to 40 HP/42″, the top heater grows from 8.75 to 10.25 Mil. BTU/hr, and most significantly, the lower module gets a major redesign with 25 HP/40″ fans (versus 15 HP/36″ on the 2320 and 2322) and 6.75 Mil. BTU/hr heaters (versus 4.5 Mil. on the 2320 and 2322).

This lower module upgrade is the engineering reason the 2326 stands apart from the rest of the 2300 Series. Where the 2320 and 2322 share an identical lower module, the 2326 requires a completely different lower module configuration to handle the higher airflow and thermal load demanded by 26-foot column drying at 2,700 BPH.

In Dry & Cool mode, the 2326 delivers 1,840 BPH at 5-point removal — the highest cooled-grain throughput available from any two-module portable dryer in the GSI catalog. For operations whose primary mode is continuous cooled-grain drying at large scale, this is the practical capacity ceiling within the 2300 Series.

Important note on All Heat capacity at 2,700 BPH: GSI’s documentation indicates that at this throughput level, in-bin cooling for All Heat-dried corn typically requires bins of 50,000 bushels or less for safe cooling and storage without active grain management. At 2,700 BPH, this often means cycling between multiple cooling bins in sequence rather than directing all output to a single large bin. Operations planning All Heat operation at peak 2326 capacity should size their cooling bin infrastructure accordingly.

Fan & Heater Configuration

The 2326 uses the standard 2300 Series 1+2 fan configuration: one fan and heater on the upper module, two fans and heaters on the lower module. However, the fan and heater specifications represent a major step up from every other 2300 Series model.

Upper module:

• 1 vane axial fan @ 40 HP, 42″
• 1 heater @ 10.25 Mil. BTU/hr

Lower module:

• 2 vane axial fans @ 25 HP, 40″
• 2 heaters @ 6.75 Mil. BTU/hr each

The 2326’s upper module specifications represent a significant step up from the 2322: the top fan grows from 30 HP to 40 HP (+33% horsepower), and the top heater grows from 8.75 to 10.25 Mil. BTU/hr (+17% thermal output). The 40 HP top fan is the largest in the entire 2300 Series — and significantly larger than anything in the 1200S&H Series, where the maximum top fan is 25 HP on the 1226.

The lower module upgrade is even more dramatic. While the 2320 and 2322 share identical lower modules (15 HP fans, 4.5 Mil. BTU/hr heaters), the 2326 jumps to 25 HP/40″ fans (+67% horsepower per fan) and 6.75 Mil. BTU/hr heaters (+50% thermal output per heater). This is the engineering reason the 2326 can support 26-foot column drying at 2,700 BPH — the lower module needs proportional upgrades to handle the higher secondary drying and cooling load.

In the 2326X X-Stream configuration, the fan layout is rearranged to optimize airflow distribution from front to back of the grain column. The benefit is most pronounced on the 2326 because of its 26-foot column length — the longest in the 2300 Series — where front-to-back heat variation has the greatest potential impact on grain uniformity.

The 2326 is three-phase only. Voltage options include 208V, 230V, 460V, and 575V:

• 208V three-phase: 302–379 amps
• 230V three-phase: 281–352 amps
• 460V three-phase: 143–176 amps
• 575V three-phase: 115–142 amps

These amp draws are substantial — the 2326 represents the highest electrical demand in the 2300 Series. Operations planning a 2326 installation should verify their three-phase service capacity well in advance and may need utility upgrades for sites that previously supported only smaller dryers. Higher voltages (460V or 575V) are strongly preferred where available because of the proportionally lower amp draw.

Grain Column & Holding Capacity

The 2326 uses standard 14-inch wide grain columns measuring 26 feet long — the longest column in the 2300 Series and identical to the 1226S/H column length in the 1200S&H Series. Total holding capacity is 1,304 bushels, with 1,261 bushels held inside the active grain column itself across both modules. The remainder occupies the loading and discharge zones above and below the dryer body.

Compared to the single-module 1226 (708 BU holding capacity at the same column length), the 2326 holds 84% more grain at any given moment. This is the practical impact of two-module architecture — two stacked drying columns mean two stacked holding capacities, plus the additional grain in the inter-module transition zone.

The 14″ column width is GSI’s standard for the entire portable lineup and is optimized for corn-sized kernels. For drying canola or other small grains, the optional small grain screen with 0.055″ perforations is available. Note that installing the small grain screen reduces corn drying capacity by approximately 20%.

Loading, Unloading & Metering

Top auger (loading): 8-inch flight driven by a 10 HP motor — the largest loader in the 2300 Series — with a peak loading rate of 3,800 BPH. The 10 HP loader is sized to fill the 2326’s larger column without extending fill time relative to smaller 2300 models.

Bottom auger (unloading): 8-inch flight in a 10-inch tube, also 10 HP. The unloading auger is sized to keep pace with the dryer’s peak metering capacity at maximum All Heat throughput.

Meter roll drive: 1 HP VFD with maximum metering capacity of 3,640 BPH — significant headroom over the 2326’s actual maximum throughput of 2,700 BPH. This margin is essential for handling capacity spikes during high-throughput drying cycles.

The VFD-driven meter roll, combined with Vision Controls, lets the 2326 target a specific exit moisture content and adjust unload speed dynamically as inlet moisture varies. For large operations handling significant grain volume per day with variable inlet moisture, this dynamic targeting consistently reduces overdrying losses by 1–2% — which on 200,000+ bushels per harvest season translates to substantial fuel and revenue savings.

Operating Modes

The 2326 and 2326X support all four standard operating modes of the 2300 Series. The three-stage architecture makes Continuous Dry & Cool particularly efficient compared to two-stage single-module dryers.

All Heat — Maximum throughput. Grain leaves the dryer hot and is cooled in-bin. Best for corn and rice operations with adequate in-bin cooling air. Peak capacity: 2,700 BPH at 5-point removal — but note the in-bin cooling capacity considerations mentioned above. At 2,700 BPH, multiple cooling bins in sequence are often required rather than single-bin discharge.

Continuous Dry & Cool — Full continuous flow with integrated cooling. Grain exits cooled and ready for direct binning at up to 1,840 BPH. The 2326’s three-stage architecture and upgraded modules make this mode particularly effective at scale — especially relevant on the 2326 where All Heat at peak capacity requires careful cooling bin management.

Staged Batch Dry & Cool — Alternating dry/cool cycles inside the dryer. Particularly useful for high-moisture corn or sensitive grains where extended exposure to heat affects quality.

Continuous Flow — Steady-state production mode for lower moisture differentials.

The 2326X X-Stream variant runs all four modes with the same capacity numbers but delivers measurably better grain uniformity at any given throughput. On the 26-foot column, this uniformity advantage is more pronounced than on shorter columns in the series — making X-Stream a particularly compelling choice for the flagship 2326 where uniformity gains scale directly with volume.

Transport & Installed Dimensions

The 2326 is engineered as a portable dryer despite being the largest unit in the 2300 Series. Operators planning to relocate the 2326 should confirm tractor or truck capacity is rated for portable grain handling equipment in the 25,000+ lb class.

Dimension	Transport	Installed
Length	35′ 2″ (hitch to discharge auger)	35′ 10″
Width	8′	8′ 8″
Height	13′ 5″ (11′ 9″ shortest)	25′ 11″ (excl. foundation supports)
Approximate Weight	25,000 lbs (less transport kit)	—

Transport height is given with both standard and shortest configurations — the lower 11′ 9″ figure assumes the discharge auger is folded down for road transport under low bridges and power lines.

The installed height of 25′ 11″ is fixed across all 2300 Series models — it represents the structural height of the two-module stack and doesn’t change with grain column length. While this is significantly taller than any single-module dryer, it remains substantially shorter than three-module 3400 Series dryers (37′ 3″ installed height) — making the 2326 a practical alternative for large operations where site height constraints matter.

At 25,000 lbs transport weight (less transport kit), the 2326 is the heaviest unit in the 2300 Series — about 2,500 lbs more than the 2322 and roughly 56% heavier than the entry-level 2314. Operators planning to relocate the 2326 between sites should confirm hitch ratings, axle capacity, and trailer specifications well in advance.

Vision Controls

The 2326 ships standard with Vision Controls — GSI’s purpose-built color touchscreen control system for grain dryers. Vision handles:

• All four operating modes with dedicated mode-select interface
• Plenum temperature setpoints for all three heaters independently (upper plenum, lower-front plenum, lower-rear plenum)
• Moisture-targeting through automatic meter roll VFD adjustment
• Full system diagnostics and fault logging
• Multi-grain profiles for fast switching between corn, soybeans, wheat, rice, and other crops

Independent control of all three plenums is one of the operational advantages of the 2300 Series over single-module dryers. The operator can fine-tune upper plenum temperature for primary moisture removal (where the 2326’s substantial 10.25 Mil. BTU/hr heater operates) while adjusting lower plenums for cooling intensity — a level of granular control that two-stage single-module dryers cannot offer.

The Vision display can be mounted directly on the dryer or remoted into a shop or office with a hardwired connection. For operations running the 2326 continuously during harvest — which is the most common use case for a flagship-size dryer — the remote display is highly recommended.

GSI Connect Remote Management

The 2326 is GSI Connect compatible, enabling phone-based remote monitoring and control through the GSI Connect mobile app. Connect functionality includes:

• Real-time dryer status (running, idle, fault)
• Live plenum temperatures for all three heaters and grain moisture readings
• Remote setpoint adjustment for each heater independently
• Remote stop function
• Unload speed adjustment
• Performance logs and runtime alerts

GSI Connect is especially valuable on the 2326 because flagship-size dryers are often run overnight during peak harvest. Remote monitoring lets the operator catch faults, verify performance, and adjust setpoints from anywhere — without physical trips to the dryer that would otherwise be required.

Historical performance data captured through Connect can also be used to optimize drying efficiency season over season — particularly valuable on a unit handling 200,000+ bushels per harvest where even small efficiency gains translate to meaningful fuel savings. At the 2326’s throughput level, these gains typically pay for the GSI Connect setup within the first harvest season.

Optional Equipment

Beyond the standard configuration, the 2326 supports several factory and dealer-installed options:

Static Moisture Sampler — Improves moisture reading accuracy by sampling only when grain is stationary. Includes debris guards to prevent fines from contaminating the sensor. Strongly recommended on the 2326 because of its high throughput where moisture targeting accuracy directly affects operating efficiency at scale.

Inverters (VFDs) — Available on the 2326. VFD upgrades allow finer control over fan and auger speeds, reducing energy consumption at partial loads.

Small Grain Screen — 0.055″ perforations for canola and other small grains. Reduces corn capacity by approximately 20% when installed.

X-Stream Upgrade (2326X configuration) — Available at order. The X-Stream fan rearrangement improves heat distribution from front to back of the dryer for measurably better grain uniformity at the same throughput. On the 26-foot column, X-Stream’s uniformity advantage is most pronounced.

Best Applications for the 2326 and 2326X

The 2326 and 2326X fit specific operational profiles, and the right configuration depends on grain quality requirements and infrastructure.

Best fit for the 2326:

• Large farms handling 10,000–15,000+ acres of corn
• Operations primarily running Continuous Dry & Cool or All Heat where grain uniformity isn’t a premium grading factor
• Three-phase farmsteads with established large-load electrical infrastructure
• Custom drying operations needing maximum two-module throughput
• Large grain elevator operations using portable dryers as primary drying capacity
• Operations that want flagship two-module performance without committing to three-module architecture

Best fit for the 2326X:

• Large-scale food-grade corn producers operating at 2,500+ BPH throughput
• High-volume seed corn operations
• Large malting barley growers (with small grain screen)
• Specialty grain producers selling into markets where overdried or unevenly dried kernels are penalized at scale
• Any large operation where the 26-foot column’s potential for front-to-back heat variation justifies the X-Stream investment

Less suitable for:

• Operations consistently exceeding 2,800 BPH demand — step up to the 2400 Series (four-fan layout) or 3400 Series (three-module)
• Single-phase farmsteads (the 2326 is three-phase only with substantial amp draw)
• Sites without three-phase electrical service capacity to support 350+ amp loads
• Smaller operations under 10,000 acres where the 2322 or 2320 would deliver adequate capacity at substantially lower cost
• Sites with strict installed height limits where even 25′ 11″ is excessive (single-module dryers may be required)

How the 2326 Compares to Adjacent Models

2326 vs 2322 / 2322X: The 2326 represents a major step up across multiple specifications: column length grows from 22′ to 26′, top fan upgrades from 30 HP to 40 HP, top heater grows from 8.75 to 10.25 Mil. BTU/hr, and the lower module gets a complete redesign with 25 HP fans (vs 15 HP) and 6.75 Mil. BTU/hr heaters (vs 4.5 Mil.). The result is 500 BPH more Full Heat capacity at 5-point removal (2,700 vs 2,200 BPH) — about 23% more throughput. The 2326 is the right step up if your typical drying volume regularly exceeds 2,400 BPH and the substantial increase in electrical and capital requirements is justified by harvest volume.

2326 vs 2426 (2400 Series): The 2426 uses a four-fan layout (two fans on each module) and four-stage drying architecture instead of the 2300 Series 1+2 fan, three-stage configuration. Capacity numbers are similar (2,700 BPH Full Heat on both at 5-point removal), but the 2426 delivers more uniform heat distribution and supports a different operational profile — better suited to high-quality batch drying and small-grain efficiency. Choose the 2326 for large-scale Continuous Dry & Cool optimization; choose the 2426 if four-stage drying or batch quality is the priority.

2326 vs 3420 (3400 Series): The 3420 is a three-module dryer at slightly shorter column length (20′) but with much higher All Heat capacity (2,950 BPH). The 3420 has a significantly taller installed footprint (37′ 3″ vs 25′ 11″) and requires more substantial site preparation. The 2326 is the right choice when two-module architecture is preferred for site, transport, or operational reasons; the 3420 is the right choice when capacity above 2,800 BPH is required and three-module height is acceptable.

2326 vs 1226S/H (1200S&H flagship): The 2326 delivers more than double the Full Heat capacity (2,700 vs 1,330 BPH) and more than triple the Dry & Cool capacity (1,840 vs 600 BPH). The trade-offs are dramatically higher capital cost, substantially higher electrical demand, three-phase requirement (1226 supports single-phase), and significantly taller installed footprint (25′ 11″ vs 14′ 6″). Choose the 2326 only when capacity requirements justify the full step up to two-module architecture; the 1226 remains the better choice for operations under approximately 5,000 acres.

Frequently Asked Questions

What is the difference between the 2326 and 2326X? The 2326 uses GSI’s standard three-fan layout for the 2300 Series. The 2326X uses the optional X-Stream fan rearrangement, which improves heat distribution from front to back of the dryer for more uniform grain quality. Capacity ratings are identical between the two configurations. X-Stream is particularly beneficial on the 2326 because of its longer 26-foot grain column.

What is the holding capacity of the GSI 2326? Both the 2326 and 2326X have a total holding capacity of 1,304 bushels, with 1,261 bushels in the active grain column across both modules — the highest two-module holding capacity in the GSI portable dryer lineup.

What is the maximum drying capacity of the 2326? At 5-point moisture removal (20% to 15%) in Full Heat mode, the 2326 delivers up to 2,700 BPH on standard corn — identical between standard and X-Stream configurations. In Dry & Cool mode at the same moisture removal, the 2326 delivers up to 1,840 BPH. This is the highest two-module capacity in the GSI portable lineup.

Can the 2326 run on single-phase power? No. The 2326 is three-phase only. The 40 HP top fan motor and 25 HP lower module fans far exceed practical single-phase service limits. For single-phase operation in the 2300 Series, only the 2314 is available.

Is the 2326 the largest GSI two-module portable dryer? The 2326 is the largest 2300 Series model. The 2400 Series (four-fan layout) offers similar peak capacity but with a different fan and stage architecture. For higher capacities, GSI offers the three-module 3400 and 3600 Series dryers.

Why does the 2326 require a different lower module than the 2320 and 2322? The 2326’s 26-foot grain column at 2,700 BPH throughput requires substantially more secondary drying and cooling airflow than the lower module shared by the 2320 and 2322 can deliver. The 2326’s redesigned lower module uses 25 HP fans (versus 15 HP on the 2320/2322) and 6.75 Mil. BTU/hr heaters (versus 4.5 Mil.) to handle the higher load — a 67% horsepower upgrade and 50% thermal output upgrade per heater.

What’s the 2326’s electrical demand at peak operation? At peak load, the 2326 draws 281–352 amps on 230V three-phase service or 143–176 amps on 460V three-phase service. Operations planning a 2326 installation should verify three-phase service capacity well in advance — utility upgrades may be required for sites that previously supported only smaller dryers.

Does the 2326 support X-Stream? Yes. The 2326X variant is available with the X-Stream fan rearrangement at order. X-Stream cannot typically be retrofitted in the field. Given the 2326’s long 26-foot column, X-Stream delivers the most pronounced uniformity benefit in the entire 2300 Series.

What’s the difference between the 2326 and the 1226S/H? The 2326 is a two-module dryer with three fans and three drying stages. The 1226S/H is a single-module dryer with two fans and two drying stages. Both use 26-foot grain columns, but the 2326 holds 84% more grain (1,304 BU vs 708 BU) and delivers more than double the Full Heat capacity (2,700 BPH vs 1,330 BPH). The 1226S/H can run with a single-to-three-phase converter on single-phase service; the 2326 requires native three-phase service due to its substantial amp draw.

What fuel does the 2326 use? Both 2326 configurations support both liquid propane (LP) and natural gas (NG), selectable at order configuration. Fuel consumption is substantial at peak operation — natural gas service is often preferred where available because of the lower per-bushel drying cost at this throughput level.

What is the transport weight of the 2326? Approximately 25,000 lbs (less transport kit) — the heaviest unit in the 2300 Series and identical between the standard 2326 and the 2326X configurations.

What is the installed height of the 2326? The 2326 has an installed height of 25′ 11″ (excluding foundation supports). This is identical across all 2300 Series models because it represents the structural height of the two-module stack — though substantially shorter than three-module 3400 Series dryers at 37′ 3″.

Does the 2326 support remote monitoring? Yes. Both 2326 configurations ship with Vision Controls and are GSI Connect compatible, enabling full remote monitoring and control of all three plenum temperatures and unload speeds. At the 2326’s high throughput level, GSI Connect is highly recommended.

Can the 2326 dry canola or other small grains? Yes, with the optional small grain screen (0.055″ perforations). Capacity on corn is reduced by approximately 20% when the small grain screen is installed.
