Refrigerant: R22, R410A

Cooling capacity: 25~199 kW Product Feature

The high purity seamless internal thread copper tube and aluminum spoiler fins are made to connect the copper tube and aluminum sheet tightly by mechanical expansion tube to achieve the best heat transfer effect.

Shell and tube heat exchanger is used for water-cooled condenser, which has compact structure, small pressure drop and high heat transfer coefficient (tube heat exchanger below KPW070 is used);

Compared with the traditional piston compressor, the completely sealed scroll compressor has stable and reliable performance, low noise and high energy efficiency ratio.

The forward curved multi-wing centrifugal double-suction impeller is adopted. The impeller is tested by dynamic balance and has no noise and vibration in long-term operation to ensure the effect of air supply.

Adopt well-known brand refrigerant system automatic control components, accurate control, stable quality;

Nylon filter, easy to load and unload, can be disassembled and cleaned at any time

Design Cooling Condition: Chilled Water In/Out 12℃/7℃;Ambient 35℃
