Air Cooled Two Stage Piston Condensing Unit

Air Cooled Two Stage Piston Condensing Unit

Advantages:

1.The unit is equipped with Bitzer semi-hermetic two-stage compressor, which is with good quality and high reliability.

2.The unit is equipped with imported well-known refrigeration parts to guarantee the reliability of operation;

3.The unit is equipped with condenser, which greatly improves the cooling capacity and energy efficiency ratio.

4.The Unit provides low evaporation temperature. The lowest evaporation temperature can reach -50℃ when R22 is applied; The lowest evaporation temperature can reach -65℃ when R404A is applied, which makes it can applied to low temperature storage and quick-frozen equipment.
