Product Description

Our high-quality Bitzer Water-Cooled Open-Type Piston Condensing Unit features Bitzer semi-hermetic piston compressor and -20～-15 ℃ temperature for stable operation. Perfect for R22, this water cooled condensing unit has water-cooled condenser (aluminum fin and copper tube) and highly efficient air-cooled condenser (shell-type) for long life and over-heat protection. An outside rotor condenser is fortified with an air cooling condenser for good appearance, high efficiency, and less noise. Moreover, waterproof junctions of Bitzer condensing units are quite easy to connect with all control components to save time.

We always provide series of products for the solution of cold storage, water-chilling and ice-making with the best quality to maintain OEM-QUALITY standards.
