Screw type low-temperature cascade unit

The screw cascade low-temperature unit uses a screw compressor as the refrigeration power source for the low-temperature stage, with a cooling water tower as the condensing medium. The unit is designed as an integrated unit for easy installation and maintenance. The output horsepower of the unit ranges from 40HP to 160HP, and the low-temperature liquid outlet temperature control range is -45 ℃ to -70 ℃
◆The screw cascade low-temperature unit can provide low-temperature refrigerant ranging from -70 ℃ to 0 ℃. It has been widely used in industries such as pharmaceuticals, electronics, tires, beverages, wires, vacuum coating, injection molding, textiles, natural gas, laser equipment, welding equipment, medical equipment, etc

Mainly using internationalhigh qualityThe new third-generation 5:6 non parametric rotor semi closed screw compressor features only three moving parts with few components and a low failure rate
Multi machine precise capacity division with wide application range of cooling capacity, single or multiple machines can achieve graded or stepless energy regulation, high efficiency, energy saving and high reliability
The whole machine is fully integrated in the factory area, filled with refrigerant, and tested for circuits, fluorine circuits, and water circuits to ensure that the equipment can be used without electrical connection upon arrival.
The control operating system, touch screen text display, microcomputer based PLC control, contactors, circuit breakers, etc. are all installed in the electrical control box.
The combination of load loading and star delta starting method greatly reduces the starting current and minimizes the impact on the power grid
