POST HARVESTWhen it Began . . .
Why is AGRI-STOR confident in its design?
There’s science in the design.
Early on, Nathan Gellert tested and re-tested his approach to Post Harvest. Today, The GELLERT Company, (Agri-Stor’s Equipment Supplier) continues to apply those principles.
The Gellert Company provides GLOBAL Climate Design, Distribution and Control for Ventilation, Humidification, and Refrigeration for a variety of industries.
Agri-Stor continues to rely on Gellert Science to manage and provide quality produce, return on valuable produce through audits, remodels, upgrades and managing that inventory.
Does the Gellert design work?
The answer is, YES!
We rely on the science and the application of that science everyday and we’re accountable for those results!
Pressurizing and Balancing
Agri-Stor creates your Post Harvest success by pressurizing your building. We do this using a perfectly designed plenum and then placing certified equipment that meets the design requirements. We don’t cut corners in design or equipment.
Creating the Perfect Climate
Once the building is sealed and pressurized, and the entire building is balanced, the system can create the perfect climate for storage without obstructions and limitations. Like water in a tank, the air freely flows to all open areas and spaces.
Climate Distribution to the Produce
To control respiration and transpiration, Agri-Stor’s air distribution method controls the climate and gets as close to the product as possible. Fans that create packets of air effectively carry the necessary humidity and climate and deliver it to the produce.
UNLIKE HIGH SPEED OPTIONS, where the humidity falls out of the air packet long before it reaches the produce, Agri-Stor’s certified fan speeds treat the produce like a human… living root vegetables like calm, consistent air flow over a 24-hour period.
Anything besides that means potatoes respirate and transpire quickly and the desired Post Harvest goals of longevity and quality fail.
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 return. Our 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.
BOX | BIN | SEGMENTED
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

– GELLERT Equipment
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 –  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.
