Our Native Industry


For almost 60 years, Agri-Stor has innovated your Post-Harvest Solutions with University-based Research and years of applied data. We were the reason Post Harvest began. And you’ll be the reason why we continue on.



Bulk is where long-term storage or Post Harvest began and is by far the most popular way to store potatoes, onions, and carrots at quality for long periods of time.

Agri-Stor’s specialty is helping Growers hold their produce longer and at a better quality allowing them to control the release of their product into the marketplace.

When going to Fresh Market, storage issues don’t need to be the reason for low returnOur Grower customers are looking for a return from the Fresh Shed.   When it comes to storage, Agri-Stor can minimize and even eliminate storage challenges – getting Growers headed in the right direction and improve produce to Processors and Consumers.

Standard Bulk Design includes a precisely designed center or mulitple plenum with sensors, High Performance Gellert Certified Fans for Ventilation, ABB Drives for Control, and Fully Rounded Duct to carry the air without resistance. Segmented control is also available and full featured.

For consistent and high performance air flow, Agri-Stor provides the Gellert Air Floor along with the Gellert Air Floor Maximizer.   

The Gellert Air Floor

The Gellert Air Floor Includes a  strategically designed floor that provides precise air flow through vents in the floor. Similar to the Gellert Air Floor, the Maximizer can drastically reduce the cost of the floor while providing the same air floor. Gellert will consult with your builder to assess capabilities and to provide more information. Both Systems include integrally controlled Fresh Air Doors with updated actuators, Ruskin Louvers, and Sensors throughout.

The Air Wall developed by Gellert in 1960 has proven to be a great way to distribute and elevate air to higher levels of a storage as well as take climate to as close to the produce as needed. The Air Floor can be planned into a poured floor or better, designed as part of a more affordable prefab option for flooring. Gellert can work with your builder to coordinate climate design.


Gellert’s design for a more segmented specialized approach for storage includes the Gellert Air Wall System and Certified Performance Fans with Metal Fan Blades. Certified means our equipment is AMCA Certified by outside industry respected organizations for air performance.  Plastic rotors flatten out at high speed, and have been and continue to be the reason for not only a low bid to win a project but also poor air quality not reaching its destination. With Gellert’s innovative simple plenum and fan house design, Airbags and Air Mixers are not needed to manage humidity, respiration, and transpiration. Intermittent High Speed approaches cause faster respiration and crop failure is imminent. Instead – Gellert relies on scientifically sound principles of science and simply pressurizes the storage where the air is consistently and gently carried as far and as high as needed, especially in Box Storage with a Gellert Air Wall. Gellert innovated the Air Wall in 1964 and it has proved extremely successful into the 21st Century.

This System is key to seed and smaller organic potato growers who want to segment and specialize their storage. They are either looking for a new storage, to upgrade and modernize their existing storage, or simply to update and take advantage of the more modern integral 24/7 365 wireless controls available today.

Typical challenges that Gellert can tackle for you include making use of an existing smaller plenum to get the job done. Gellert’s innovative approach to Plenum Design has overcome size challenges when updating Storages with a more modernized system.

Your Box or Bin Storage includes:

  • An Effectively Designed Plenum
  • Plenum Sensors throughout
  • Certified Ventilator Fans
  • ABB Drives
  • The Gellert Air Wall
  • Humidification Options (ex: Gellert Climacell Media)
  • Ruskin Louvers
  • Correctly Sized Fresh Air Doors with Modern Actuators
  • Agri-Star Control Panel with 24/7 365 Internet Access via Our Gellert App
  • Wireless Gellert Internet Access “We can be your Internet Service Provider”.
In travels around the Globe, we see the consistent, positive results of simple science done right. In side by side comparisons of competing designs, with evaluation of crops held in storage over a one to two year cycle, the Gellert System is superior and simple.


 – GELLERT Equipment


Where Post Harvest Ventilation is concerned, Agri-Stor doesn’t cut corners, there’s too much at stake. All GELLERT fans are AMCA Certified which are key to performance but also to qualify for utility incentive programs and meet standard criteria. It’s a tough test but our customers deserve it.


Inconsistent seasonal temperature challenges are easily solved with Refrigeration. Gellert can help with a variety of affordable solutions depending on your budget. From Fixed Condensing Units, Portable, Unit Coolers and more Gellert can adapt to your refrigeration needs.


Gellert’s GDC Door Controller is simple to operate, reliable, and provides precise control of ClimaSeal Doors or Fresh Air Louvers. Service features include status indicating LEDs for all signal power and fusing and full manual override of all control functions to insure simple trouble shooting.


Gellert’s ClimaSeal Fresh Air doors are sized specifically for your Gellert Certified ventilation system.

Gellert Fresh Air Doors:

Provide a complete air seal to prevent heat transfer and provide precise and consistent temperature control.

Are manufactured with a vinyl frame and door insert, ClimaSeal doors guarantee a uniform appearance that will not fade or discolor due to extreme weather conditions.

ClimaSeal doors can be hinged on either the top or side of the frame to allow for easy installation in any size or style of building.


New for 2018, we now provide replacement pre-hung exterior/interior or slab only replacement doors. Damaged or ineffective doors account for short circuiting the air into the storage. To counter this effect, the Gellert Door easily resists the high humid environments of the storage and is built to hold up to the high pressure environments.  The interior structure of our dovetail interlocking door panel is a multi-chamber structure – [36] 1″x 1 3/4″ chambers the length of the panel with an external wall thickness of .070″.

Each panel is made with 100% virgin, exterior-grade PVC which has a Class C rating and will not support mold or mildew, per ASTM D3273 and D3274. Each door is wrapped with a 302 Stainless frame support and includes our custom made drop lock door latch. Built like a tank, the latch withstands high pressure pushes and pulls that happen inside.


Agri-Stor’s Centrifugal Humidifiers manufactured by GELLERT provide a simple solution to a variety of humidification needs, as they are completely self-contained and require only a water supply and electrical connection for operation. Specifically designed for minimum maintenance, the fan and disc are the only moving parts and all parts coming in contact with water are made using stainless steel, copper, brass and aluminum materials to insure corrosion resistant operation.


The Gellert Linear Actuator features a potentiometer for precise positioning and integral adjustable limit switches to automatically shut off actuator within desired operating ranges. Housing and motor are fully sealed to protect all internal components from harsh environments. When integrated with the Agri-Star Control Panel, the actuator offers precise temperature control and is available in a variety of stroke lengths.


Our goal is to respond to industry feedback and provide the most advanced technology available in control systems. A great example of this commitment is the introduction of the Agri-Star™ Control Panel.

The Agri-Star™ Control Panel features a large, full-color touch screen display, complete on-screen graphing, multi-mode CO2 control, plug and play internet-ready communications that requires no proprietary software to operate, user friendly and clear operating interface, on-board help menus, and software flexibility to control both Potato and Onion systems.


Gellert’s Ruskin® Backdraft Exhaust Dampers are gravity operated and open with air flow and pressure. Every damper is built with performance in mind and tested per AMCA standards in Ruskin’s Laboratory. Backdraft design prevents air from entering the building through the Exhaust Dampers. Damper blades are constructed from .050” thick extruded aluminum with extruded vinyl blade edge seals and are mounted in an aluminum frame with synthetic bearings. Gellert’s Ruskin® Backdraft Exhaust Dampers provide high performance with minimal maintenance to guarantee a long operational life.
