Product Features
　　　

◆Air cooled screw type low-temperature chiller unitIndependent refrigeration system design, multi head units are relatively independent, with minimal moving parts and reliable operation.
◆ Adopting imported high-efficiency economical semi enclosed twin-screw compressor, it has high energy efficiency, reliable operation, and long service life.

At the minimum load (25%), each refrigeration system compressor starts with star delta voltage reduction, effectively reducing the starting current and impact on the power grid.
The flexible adjustable design enables continuous energy regulation (stepless adjustment) of the air-cooled screw refrigeration unit between 25% and 99%, ensuring the efficiency of the compressor and helping users save operating costs.
◆Air cooled screw type low-temperature chiller unitAdopting high-precision large screen touch screen, industrial grade intelligent controller and computer control system, fully digital display, connected with external devices, remote users and control room can be connected through standard interfaces to achieve the following multiple control functions.
Multiple protection functions: compressor exhaust over temperature, motor over temperature, cold water anti freezing, etc. Temperature protection: overcurrent, phase loss, reverse phase, etc. Electrical protection: refrigerant system high and low voltage, oil level, water cut-off and other emergency state protection. Necessary maintenance and management functions such as alarm, prompt, recording, retrieval can be set for the above protection functions.
Automatic power on/off, automatically achieving unmanned operation management according to the predetermined work plan.
Multiple password settings ensure that the device will not shut down or be damaged due to accidental factors.
◆ Realize remote data collection, operation inspection and control, fault diagnosis and other management functions through LAN or Internet.
◆ Choose international control components such as thermal expansion valves, solenoid valves, and one-way valves to ensureAir cooled screw type low-temperature chiller unitEfficient and reliable operation within a wide range of operating conditions.
Adopting a dual cycle coupled refrigeration method with an energy-saving device to improve efficiencyAir cooled screw type low-temperature chiller unitWork ability and energy-saving efficiency.
After comprehensive testing and full load operation testing by the manufacturer, the product is shipped with refrigerant to ensure that the equipment can start working after water and electricity are in place.
The compressor is equipped with an exhaust muffler to ensure low-noise operation of the air-cooled screw chiller unit.
◆Air cooled screw type low-temperature chiller unitThe refrigeration components are all branded, greatly improving the reliability of the entire machine.
