LG4 -45°C ~ -10°C Screw Chillers

Product Description Product Parameters Custom Design

screw-chiller

This series of equipment is suitable for various chemical, pharmaceutical, mechanical and other fields of production process cold source, can provide -110℃ ~ +30℃ refrigeration medium, can be used as ice storage, low temperature air supply and other production process required process cold source. Our company can design the unit according to the user's requirements.

The unit adopts advanced semi-enclosed screw compressor, low carbon energy saving and environmental protection; good performance, low noise, trouble-free operation can reach more than 100,000 hours; temperature control can be step energy regulation or stepless energy regulation control. According to the heat load required by the specific production, the outlet water temperature of the refrigerant is used as the control point, and the instructions are sent through the control center. The load of the compressor unit is adjusted through the movement of the energy regulation slide valve to achieve a real energy saving effect.
