Protect Your Grain Investment with Reliable Cooling
Once grain is dried, maintaining the correct storage temperature is critical. Tryac cooling control panels automate your fans and monitor conditions around the clock, so you can store grain safely for months without risk of heating, insect damage or quality loss.
Why Choose Tryac Cooling Panels
Automated Fan Control
Intelligent controllers run your cooling fans only when ambient conditions are right, reducing electricity costs while keeping grain at the optimal temperature.
Temperature Monitoring
Continuous monitoring of grain and ambient temperatures with configurable alarm thresholds. Know immediately if conditions change and action is needed.
Energy Efficient
By running fans only when conditions are favourable, our panels can significantly reduce your electricity bill compared to timer-based or manual cooling.
Built to Last
Industrial-grade components and robust enclosures ensure reliable operation season after season, even in dusty and demanding farm environments.
Flexible Installation
Compatible with most grain store layouts and fan setups. Whether you have a single bin or a multi-bay floor store, we design a system to suit.
Expert Support
From initial design through to installation and ongoing maintenance, our team of agricultural electrical engineers supports you every step of the way.
Cool Smarter, Not Harder
Tryac cooling panels use ambient temperature and humidity data to determine the ideal times to run your fans. The result: lower grain temperatures, less energy consumption and better grain quality throughout the storage period.
Our Cooling Products
Differential Temperature Controller for Roof fans
The Tryac DTC-2 roof fan controller is designed to remove hot air above the crop by using cooling ambient air. Easy to use control dials and operator indicaion provide ease of use.
DTC-1 Differential temperature controller
The DTC-1 is a low cost simple to operate differential temperature controller for the use in small potato stores, onion and grain stores. The controller lowers the temperature of the stored crop by using lower ambient temperatures than the crop to ventilate and lower the crop temperature.
DTC-2 Distribution Unit
The DTC Distribution box is a differential temperature controller designed to control low volume fans and to be placed on the crop to reduce the number of trailing leads normally required to supply the fan and controls.
DTC-2 Differential temperature controller
The TRYAC DTC-2 has been designed to control the low volume fans used to ventilate the crop. It can be used to control a single fan on a grain silo or multiples of fans on floor stores.
DTC-3 Differential temperature controller
The DTC-3 ensures aeration only occurs when ambient air benefits stored grain temperature — maximising cooling efficiency while eliminating unnecessary fan operation.
How It Works
Consultation & Survey
We visit your farm to assess your grain store, fan setup and storage requirements. We then recommend the right cooling solution for your needs.
Design & Manufacture
Your panel is designed and built in our Grantham workshop using industrial-grade components, thoroughly tested before leaving our premises.
Installation & Setup
Our engineers install the panel on-site, connect your sensors and fans, and calibrate the system for your grain type and store conditions.
Ongoing Support
We provide training, seasonal servicing and telephone support. Spare parts and repair services are always available when you need them.
Grain Cooling for UK Farms
Effective grain cooling is one of the most important steps in long-term grain storage. Even after drying grain to a safe moisture content, high temperatures in store can lead to insect activity, mould growth and a rapid decline in grain quality.
Tryac has been manufacturing grain cooling control panels for over 30 years, supplying farms across Lincolnshire, East Anglia, Yorkshire, the South East and beyond. Our panels are designed to work with all common fan types and grain store configurations, from small on-farm bins to large commercial floor stores.
Why Cooling Matters
Grain insects become active above 15°C and breed rapidly above 20°C. By cooling stored grain below these thresholds, you can virtually eliminate insect damage without the need for chemical treatment. Properly cooled grain also maintains better bushel weight, germination rates and baking quality.
How Automatic Cooling Saves Money
Running fans continuously is expensive and often unnecessary. Tryac automatic controllers monitor ambient temperature and only operate fans when the outside air is cool enough to reduce grain temperature. This targeted approach typically reduces fan running hours by 50–70% compared to timer-based systems, resulting in significant electricity savings.
All our panels are designed and built at our workshop in Grantham, Lincolnshire. We offer installation across the UK and provide ongoing support and repair services to keep your cooling system running reliably.
