Low Temperature Water-Cooled Piston Condensing Unit

Low Temperature Water-Cooled Piston Condensing Unit

Advantages:

1.The unit equippedwith Bitzer semi-hermetic piston compressor of high quality and stable operation.

2.Air cooling condenser(copper tube and aluminum fin type) or water cooling condenser (high efficient tube and shell type) is applying to guarantee high heat exchange rate and long life.

3.Air cooling unit equipped with the external rotor condenser, which isless noise, high efficiency and good appearance. 

4.A full set of high quality imported or domestic accessories guarantee stable operation.

5.Water proof junction boxis equipped, easy to connect all control components.

6.We offer a series of products for the wide temperature rangeto provide solutions of freshness preservation,cold storage, ice-making, water-chilling, etc.
