WATER COOLER WRK-2

HOFFMANN Continuous-Flow Coolers DRK are the powerful solution to cool clean fluids. Their compact design minimises installation space requirements. The units are suited for single or multiple circuit systems and are universally suitable for simple and complex applications. Continuous-Flow Coolers have a pump to transport the fluid to be cooled into the evaporator of the cooler. Depending on the application, the evaporator may be a plate or a tube heat exchanger. The inflowing fluid is cooled by transferring its heat to the environment via the air-cooled condenser. The coolant temperature is...
