FrigorTec KK 310 Tropic

Granifrigor KK 310 Tropic Grain Cooling Unit

Compact, mobile cooling unit, fully mounted in a plastic-coated frame, designed for the refrigerated preservation of grain, oilseeds, and other bulk materials, featuring automatic hygrotherm post-heating (Hygromat) for controlling cold air humidity.

The Granifrigor Tropic series grain coolers are engineered for optimal performance and energy efficiency, perfectly matched to the temperature and humidity conditions of tropical climates.

Application Range
Reliable grain cooling in tropical zones (heat, high humidity, monsoon, and fog conditions). Secure humidity control with HYGROMAT™ automatic system.
Outstanding suitability and dependable operation even in extremely high ambient temperatures thanks to safety refrigerant.

Handling and Operation
- Especially powerful compressors and large heat exchangers designed for tropical conditions
- Quiet standard operation via frequency-controlled fans and sound-optimized compressors
- Effective, large-area filters with integrated filter monitoring
- Increased safety with backpressure display
- Optimal monitoring through inspection window in the air cooler
- Reliable start-up even at low outside temperatures thanks to speed-regulated condenser fans
- Easy and thorough cleaning due to excellent accessibility, including heat exchangers with wide fin spacing, housing doors, manholes, and inspection openings in the air duct

Energy & Environmental Balance
- Economical solution with low power consumption
- Energy-efficient thanks to frequency control and state-of-the-art motors
- Environmentally friendly safety refrigerant – free of CFCs and HCFCs
- Additional energy savings via winter and summer thermostat
- Continuous maintenance and monitoring of desired cooling air humidity and temperature with HYGROTHERM
