Hebei screw-type low-temperature refrigeration refrigeration unit is also a type of low-temperature freezer. Its main component refrigeration compressor uses a screw-type compressor, so it is called a screw-type refrigeration unit. Its frozen effluent temperature ranges from 0 ° C to -35 ° C. It can be widely used in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing and other industrial freezing processes where frozen water is used, or in factories, hospitals, etc. Areas where centralized cooling of chilled water is required in various central air-conditioning projects.

Product features of Hebei screw cryogenic refrigeration unit :

First, the highly efficient semi-hermetic screw compressor refrigeration compressor uses imported high-quality screw compressors, its 5: 6 ultra-efficient screw rotor compressor, 20-30% higher energy efficiency than general compressors. High reliability and efficiency, easy maintenance, Accurate capacity control and wide application range.
1.Zui new asymmetric rotor tooth profile.
2. Four-stage or stepless capacity control system.
3. Built-in differential pressure oil supply lubrication system.
4. Low vibration and low noise.
Second, the microcomputer accurately controls the temperature and operates automatically. The microcomputer controller uses a super-large-screen PLC LCD display, with a good full Chinese man-machine dialogue interface to achieve full-featured automatic control. The LCD screen displays the machine's working status in real time, and the precise monitoring of the group's operation is in good condition. The touch panel is well sealed, waterproof, dustproof, corrosion-resistant, and has a long key life.
Graded and stepless energy control is used in general air-conditioning systems, equipped with 100%, 75%, 50%, 25% graded energy control systems. This ensures that the unit can play an energy-saving effect at part load. However, if precise control of the water temperature is required, User requirements, all models can be equipped with stepless energy control.
Third, high operating efficiencyThe heat exchanger uses high-efficiency bellows, plus an efficient screw compressor to ensure the unit's high-efficiency operation.
Zui reliable protection and accessories.
The refrigeration unit has the following components to prevent any malfunction: compressor protection timer, overcurrent relay, compressor motor temperature sensor, anti-freezing temperature controller, sight glass, oil heater, compressor reverse phase protection relay, High and low pressure protection, exhaust high temperature protection, safety valve, easily soluble plug.
After sales service

1. The buyer department can go to our company for free equipment operation training;
2. For the equipment sold by our company, the free warranty period is a leap year. During the warranty period, spare parts and repairs are provided free of charge; however, all abnormal damage to the equipment is not covered by the warranty, and the buyer shall pay the cost of replacement parts.
3. Outside the free warranty period, when the equipment is damaged, the buyer must pay the cost of the replacement parts (based on the material procurement cost);
