20HP Two Stage Piston Air Cooled Refrigerant Condensers Unit For Blast Freezing
Air Cooled Two Stage Piston Condensing Unit
The Unit provides low evaporation temperature. The lowest evaporation temperature can reach -50℃. The lowest evaporation temperature can reach -65℃ when R404A is applied, which makes it can be applied to low-temperature storage and quick-frozen equipment.
● The shell is of box structure with a secure connection and the compressor power is from 1hp~35hp which is suitable for both the hermetic and semi-hermetic compressors in various brands;
● All the units are tested under 2.8Mpa gas tightness and pollution discharge which is suitable for R22, R134a, R404a, R407c refrigerants, etc;
● Coldlink condenser is of a wide surface with excellent performance in heat exchanging which is widely used for various condensing units;
● All the fans are axial fans which are easy to install and maintain with stable operation and low noise.
