I have the chiller you want

definition:
The screw chiller is usually called a screw chiller because its heart component compressor is a screw type. Screw chiller is usually a high-power unit with an input power of 30KW and a refrigeration power of 100KW or more; it is commonly used in large-scale refrigeration projects such as chemical, steel, and construction.
Screw chiller has the following advantages:
1. High reliability. Screw compressors have fewer parts and no wearing parts, so they operate reliably and have a long life.
2. The operation and maintenance are simple and convenient, and there is no need for professionals to perform routine maintenance.
3. Small size, light weight and small footprint.
4. Energy-saving and environmental protection. The compressor comes with a 15% -100% capacity regulating valve, which automatically adjusts energy according to the operating conditions and temperature.
5. The screw chiller has a wide adaptability. From different operating environments, operating temperature conditions and characteristics, the screw chiller can be well adapted and stable.
1. It can also realize automatic adjustment during operation to maximize energy saving.
2. Chassis shell The shell adopts electrostatic spray anti-rust treatment, with beautiful appearance and reasonable structure.
3. According to user needs, the installation method of industrial air cooler can be integrated or split.
4. Functionally, the industrial air cooler can have functions such as cooling and heating, humidification or dehumidification at the same time.
Supporting industries:
Screw chiller can meet the demand for large power refrigeration. The main host is commonly used in central air-conditioning, chemical industry, steel casting, breeding industry, petroleum gas and many other fields.
