Grain cooling device

FrigorTec KK 310 Tropic

Granifrigor KK 310 Tropic Grain Cooling Unit

Compact, mobile cooling unit, completely mounted in a plastic-coated frame, for the cold preservation of grain, oilseeds, and other bulk goods. It features an automatic Hygrotherm reheating system and Hygromat for regulating cold air humidity.

The Granifrigor Tropic series grain cooling units are optimally designed in terms of performance and energy consumption for the temperature and humidity of tropical climates.

Area of ​​Application
Reliable grain cooling in tropical climates (heat, high humidity, monsoons, and fog) – reliable humidity control thanks to the HYGROMAT™ automatic system
Excellent suitability and reliable operation even at very high outside temperatures thanks to safety refrigerants

Handling and Operation
Particularly powerful compressors and large heat exchangers for tropical conditions
Quiet normal operation thanks to frequency-controlled fans and a sound-optimized compressor
Effective, large-area filters with integrated filter monitoring
Increased safety thanks to backpressure indicator
Optimal control thanks to the viewing window in the air cooler
Reliable start-up even at cool outside temperatures thanks to speed-controlled condenser fans
Easy and thorough cleaning thanks to good accessibility, e.g. E.g., through heat exchangers with large fin spacing, housing doors, manholes, and inspection openings in the air duct.

Energy and environmental balance
Economical solution thanks to low power consumption
Energy-efficient design thanks to frequency controls and state-of-the-art motors
Environmentally friendly safety refrigerant – CFC-free and HCFC-free
Further energy savings thanks to winter and summer thermostats
Permanent maintenance and monitoring of the desired cooling air humidity and temperature with HYGROTHERM
