The GK 240/448-DWM is one of our most powerful refrigeration units – designed for large quantities of grain and maximum efficiency. With an impressive cooling capacity of 65.600 W and a daily output of up to 250 tons of grain This model ensures reliable cooling even under demanding conditions – chemical-free, precise and economical.
The modern dual refrigeration circuit control, combined with intelligent control and touch panel control, guarantees maximum operational reliability and energy efficiency.
Self-monitoring, computer-aided microprocessor control with memory for device and system data. Settings via rotary knob, parameter and operating status display via touch panel. All known operating procedures, such as granosafe, granotherm, and granoplus, are functionally integrated into the control process.
Maximum efficiency through motorized refrigerant dosing and two separate refrigeration circuits.
170 t/d (normal summer output) to 250 t/d (maximum output)
Reference: At an ambient temperature of 22 °C, 50% relative humidity, and 17,5% grain moisture, 170 t of grain are cooled to 10 °C in 24 hours, including 2 K (°C) granothermal after-heat.
