FrigorTec KK 310 Tropic

Granifrigor KK 310 Tropic Grain Cooling Unit

Compact, mobile cooling unit fully mounted within a plastic-coated frame, designed for the preservation cooling of grain, oilseeds, and other bulk materials. Features automatic Hygrotherm post-heating with Hygromat control for regulating cold air humidity.

The Granifrigor Tropic series grain cooling units are optimized in performance and energy consumption for temperature and humidity conditions found in tropical climates.

Application range
Reliable grain cooling in tropical climates (heat, high humidity, monsoons, and fog) – secure humidity control thanks to HYGROMAT™ automatic regulation
Outstanding suitability and reliable operation even at very high outside temperatures using safety refrigerant

Handling and operation
Especially powerful compressors and large heat exchangers designed for tropical conditions
Low-noise operation thanks to frequency-controlled fans and sound-optimized compressor
Effective, large-area filters with integrated filter monitoring
Increased safety due to counter-pressure indicator
Optimal control via inspection window in the air cooler
Reliable start-up even at low external temperatures thanks to speed-controlled condenser fans
Simple and thorough cleaning due to good accessibility, e.g., heat exchangers with wide fin spacing, service doors, manholes, as well as maintenance openings in the air duct

Energy and environmental balance
Cost-effective solution due to low power consumption
Energy-efficient design using frequency controls and the latest generation of electric motors
Environmentally friendly safety refrigerant – CFC-free and HCFC-free
