The GK 320/448-DWM is the most powerful cooling unit in the Goldsaat series – designed for industrial use with the highest demands on performance, efficiency, and control. With an impressive cooling capacity of 94.200 W and a grain capacity of up to 350 tons per day It is the first choice for large warehouse operations that want to ensure uncompromising quality.
Thanks to state-of-the-art dual refrigeration circuit technology and intelligent control with touch panel, the system runs with high precision and economically – with full control and minimal energy consumption.
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.
250 t/d (normal summer output) to 350 t/d (maximum output)
Reference: At an ambient temperature of 22 °C, 50% relative humidity, and 17,5% grain moisture, 250 t of grain are cooled to 10 °C in 24 hours, including 2 K (°C) granothermal after-heat.
94.200 W (69.660 kcal/h) at 0/30 °C evaporation/condensation temperature
with a total plant back pressure of:
1.000 Pa (102 mm WS): 10.000 m³/h
2.000 Pa (204 mm WS): 8.450 m³/h
