water-cooled screw machine

Water-cooled screw machine is a kind of refrigeration equipment commonly used in industrial production, mainly for cooling and compressing gases. It adopts a screw compressor as the core component and uses a water-cooled cooling system to reduce temperature and improve efficiency. Water-cooled screw machines are commonly used in the refrigeration systems of large factories, commercial buildings and large facilities, and are widely recognised for their cooling effect and stability.

The working principle of water-cooled screw machine is to compress low-pressure gas into high-pressure gas by screw compressor, then cool the high-temperature and high-pressure gas into liquid state by condenser, and then decompress it to form low-temperature and low-pressure gas by expansion valve to realise the refrigeration effect. Water-cooled screw machine reduces the temperature of high temperature gas through water-cooled heat sink to cool it quickly and improve efficiency.

Water-cooled screw machine has a wide range of applications in industrial production, it can effectively reduce the energy consumption of the refrigeration system and improve production efficiency. At the same time, water-cooled screw machine also has the advantages of stable operation, low noise, easy maintenance and so on, favoured by many enterprises and users.

Performance Features
