◆ Temperature range 5℃~-60℃
◆ Use imported well-known brand compressors, such as BITZER, Copeland, Siemens, Danfoss, etc. Use single-stage or double-stage compressors
◆ Adopt single-stage, double-stage or cascade refrigeration system
◆ Use pump-less built-in differential pressure lubrication system, energy saving, high efficiency and reliability
◆ Use internationally famous brands of thermal expansion valve, solenoid valve, one-way valve and other control components to ensure the unit to work efficiently and reliably in a wide range of operating conditions
◆ Equipped with a liquid refrigerant injection system under low temperature conditions, which can effectively reduce the work load and exhaust temperature of key components. The compressor’s working reliability has functions such as hot gas bypass, energy adjustment, and complete automatic protection (overpressure, over Overload, reverse, etc.)
◆ Large-scale systems use open-type screw compressors, which have fewer moving parts and long bearing life. Small and medium-sized systems use single-stage semi-hermetic piston compressors or two-stage screw compressors. The compressor uses star-delta pressure reduction under minimum load. Starting, effectively reducing the starting current and the impact on the grid
◆ The product is fully inspected and passed the full-load operation test before leaving the factory with refrigerant to ensure that the equipment can work when the water and electricity are in place.
