Product Description
Brand New Profile Oxidation Directly Cooled High Efficient Flooded Screw Style Chiller
Basic design parameter
It adopts imported brand of compressor from Europe equippted with QINGFENG patent high-efficient anti-corrosion evaporator and high efficient anti-corrosion condenser. Moreover, automatic computer control of touched screen operation makes COP nver 5.34
It is unnecessarily to install plate heat exchanger, freezing water pump and water tank. The direct cooing method can save at least 37% electric cost than indirectly cooling method.
When temperature difference of frozen liquild is controlled within 2° C, the temperature of oxidized frozen liquild is kept uniform by special frozen technical, which ensure the products filam and color average, avoid instability quality.
It can also supply free charge 55° C hot water, In winter when the ambient temperature is below 12° C, chiller is power consumption can be zero.
Match equipment
Water cooling chiller shall be used with the cooling tower, no matter the ambient temperature is the refrigerantion efficiency could remain the best, this machine is in elegant appearance by using electrostatic spray powder shell and European design.
