Multifunction box freezer full of imported world famous scroll compressor has a flexible configuration shock pads and screws dedicated chilled water machine wholesale, has run pan, low noise characteristics; built-in security protection against over-temperature and exhaust prevent liquid strike back cryogenic gas characteristics; efficient power. For users of different conditions, we will offer adapted solutions. 1. Heat oil user adoption of our quality workmanship and oil pipeline pump for circulation, overcome transmission oil temperature and leakage. 2, the user using acid, alkali and other chemical substances quality workmanship, we stainless steel pumps and titanium tubes, PVCtp for recycling, overcome acid, alkali and other chemical substances corrosion. 3, the user viscous solution using chilled water quality workmanship factory, we have a solution circulating pump and piping to do to overcome the viscous flow and ensure energy exchange. Screw chiller its key components - the use of screw compressors named screw chillers machine screw chillers, evaporator unit out of state for the refrigerant gas; later by adiabatic compression refrigeration compressor repair water into high temperature high-pressure state. Gas refrigerant is compressed, in the condenser, isobaric cooling condensation, condensed into a liquid refrigerant after the change, and then expanded to a low pressure through the throttle valve into the gas-liquid mixture. Wherein the liquid refrigerant under low temperature and pressure, the cold heat absorbing material is in the evaporator, back into a gaseous refrigerant. Gaseous refrigerant enters the compressor through the pipe again, beginning a new cycle. This is the four processes of the refrigeration cycle. Also screw chiller major works.
