1. Our factory in Shanghai - 15,000 square meters of production area

2. Key Features of the Air Cooled Screw Chiller

1) Cooling capacity ranges from 180kW to 1520kW.

2) Designed for chilled water inlet at 12Â°C and outlet at 7Â°C with ambient temperature of 35Â°C.

3) Input power: 3P-380V-50Hz, allowing voltage fluctuations up to Â±10% and phase voltage difference within Â±2%.

4) Noise measurement taken 2m in front and 1.5m high, averaged across four dimensions.

5) Equipped with a semi-closed 5:6 asymmetric twin-screw compressor from a world-renowned brand, ensuring over 100,000 hours of trouble-free operation.

6) Eight-stage volume control or 0%-100% automatic regulation for optimal performance.

7) High-performance fluoride-resistant motor imported from France.

8) PLC microcomputer control system from Germany's Siemens with an LCD touch screen, supporting both English and Chinese interfaces.

9) Wide range of chilled water temperature adjustment to meet industrial needs throughout the year.

10) Environmentally friendly refrigerants R407C or R134A available for user choice.

11) Free step-down triangle star starter included.

12) Dual refrigeration circuits for backup support.
