Pure Cooler evaporators are a single pass dry evaporator for air conditioning and process refrigeration with evaporating temperatures from 0 ° C to + 10 ° C. Pure Coolers are optimized to use refrigerants R134a and R1234ze at low pressures (16.5 bar), with a single pass The counterflow design and patented refrigerant distribution system can significantly reduce the evaporating temperature. Power range from 100 to 1,750 kW. There is a wide range of materials to choose from, as well as a large selection of pressure vessel certifications.
