Air-cooled screw chiller unit
| Product Details
Screw-type air-cooled industrial units feature a high‑performance dual‑screw compressor paired with our factory‑manufactured, high‑efficiency finned condensers and evaporators, along with branded external‑rotor fans. Cooling capacity ranges from 148 kW to 1,051 kW. Chilled water temperature can be adjusted between 5°C and 20°C, and the ambient operating temperature spans –25°C to 43°C. Customized non‑standard units are available to meet specific customer requirements. The unit requires no cooling tower.
The tower and cooling water pump feature a compact design, easy installation, and convenient cleaning and maintenance, making them particularly well-suited for industrial processing, greenhouse cultivation, aquaculture, corrosion‑resistant applications, and use in high‑altitude areas with limited water resources.
