Product Description
Flexible solutions for all needs
Tornum Grain Coolers are available in a range of sizes—from farm installations to larger industrial systems. The units are designed for easy installation and transport.
Reliable design
For dependable and long-term operation, the system is built with a focus on robustness, quality, and durable technology:
- Automatic defrosting via hot gas (when operating with a compressor)
- Robust and reliable compressor technology
- Environmentally friendly refrigerant (R1234ze) with a very low GWP value
- High-quality components for maximum service life and minimal maintenance
The low GWP value means significantly lower climate impact compared to traditional refrigerants, making the system a future-proof choice from both an environmental and regulatory perspective.
The design is developed to deliver stable performance over time and ensure safe and sustainable grain storage.
Advanced air treatment
The air used in the cooling process is carefully treated:
- Powerful radial fans (centrifugal fans) for even airflow
- Option for high-pressure fans in certain models
- Heat exchanger with copper tubes and aluminum fins
- Integrated dehumidification through condensation
- Washable filters that normally do not need replacement
The cooled air is distributed through the grain mass via a duct system in the silo or storage facility.
Full control and monitoring
The system is equipped with modern control technology:
- PLC control (Siemens in CHARLY models, Allen-Bradley in TURBOGRAIN models)
- User-friendly touchscreen interface
- Inverter-controlled fans
- Option for remote control via Ethernet or Wi-Fi
Operating data is continuously recorded, including:
- Temperature and humidity
- System pressure
- Operating time and defrost cycles
Built on experience and proven technology
Tornum has extensive experience in solutions for grain handling and storage. By combining technical expertise with a practical understanding of the needs of agriculture, reliable and efficient systems are delivered.
The result is a solution developed to perform in real storage environments—with a focus on reliability, energy efficiency, and ease of use.
Intelligent and automated operation
The Tornum Grain Cooler monitors and controls the cooling process using an advanced sensor system that continuously measures:
- Outdoor air temperature and humidity
- Temperature of the treated air
- Pressure and temperature in the cooling system
- Airflow into the silo or storage
The system automatically adjusts operation and cools the grain step by step, ensuring a consistent and gentle reduction in temperature.
Energy-efficient technology
The system is designed to minimize energy consumption:
Free Cooling
Utilizes cool outdoor conditions for cooling without compressor operation.
Energy-saving function
The compressor automatically switches off when conditions allow.
Ventilation mode
Operates as an intelligent ventilation system based on temperature and humidity.
Flexible solutions for all needs
Tornum Grain Coolers are available in a range of sizes—from farm installations to larger industrial systems. The units are designed for easy installation and transport.
Adapted operation for varying climate conditions
The system is designed to operate efficiently under changing climate conditions. At lower outdoor temperatures, it runs without the compressor, using ambient air for cooling in combination with fans (and optionally an electric heater).
Why choose the Tornum Grain Cooler
