  The structure of low-temperature chillers is similar to that of piston chillers. Low-temperature chillers generally refer to chillers whose outlet temperature is less than or equal to 5°C. They are mainly used for process cooling in food processing, chemical, pharmaceutical and other industries. Low-temperature chillers are usually used for low-temperature requirements on certain special production lines in the industry. Low-temperature chillers can generally reach about -40°C. Low-temperature chillers  are quite different from conventional chillers in terms of unit design due to the lower temperature of the outlet water. The most basic difference is that on the chilled water side, the cryogenic unit needs to be added with the appropriate type and concentration of antifreeze. Low-temperature chillers include low-temperature air-cooled chillers, low-temperature water-cooled chillers, low-temperature screw chillers, and low-temperature piston chillers. So how to control the temperature
