Screw Compressor Supplier & Factory

Yuzhen’s Screw Compressor is manufactured by Shanghai Hanbell. It is a professional factory specializing in the production of screw compressors and related products.

We have independently developed a variety of refrigerant screw compressors to meet different needs in industrial production. Freezing screw compressors are mainly used in cold chain logistics, fresh-keeping cold storage at 0°C to -18°C, meat refrigeration and dairy product cooling in food processing, and chemical process cooling water systems. Low-temperature screw compressors are suitable for food quick-freezing at -30°C to -45°C, vacuum freeze-drying in pharmaceuticals and food, as well as certain chemical reaction processes such as carbon dioxide liquefaction. Air-conditioning screw compressors are used in commercial building central air conditioning for shopping malls, hotels, and office buildings, as well as in regional centralized cooling and heating stations. High-temperature heat pump screw compressors replace boilers to produce hot water or steam above 85°C, which is applied in electroplating, slaughtering, textiles, and food processing, while also recovering heat from wastewater, exhaust gases, and process cooling water.

We also offer air end, including both single stage air end and two stage air end. The choice between different air end is based on the required discharge pressure and operational cost considerations. Single stage air end is economical and straightforward, making them the ideal choice for applications with conventional, non-demanding pressure requirements. In contrast, two stage air end is suitable for applications with strict requirements regarding air temperature and reliability, offering significant energy-saving benefits and a longer service life.

Hanbell screw compressor offered by Yuzhen, manufactured in China, features an independently cooled motor design that separates the motor chamber from the compression chamber. A small amount of liquid refrigerant is used to cool the motor, maintaining it within an ideal operating temperature range while extending the motor's service life. The gaseous refrigerant after cooling the motor then enters the compression chamber for supplementary gas injection, preventing cooling capacity loss caused by motor cooling and enhancing the compressor's refrigeration capacity, with particularly noticeable effects in low-temperature applications.
