Double Compressors Water-cooled Low Temperature Screw Chiller 


A Screw chiller is an assembled refrigeration unit composed of screw refrigeration compressor, condenser, throttling device, lubricating oil pump, electrical control box and other components. It has compact structure, stable operation, easy operation, and stepless cooling capacity. The advantages of adjustment, small floor space, and wide range of use are suitable for large air conditioners such as hotels, hotels, factories, hospitals, etc., especially for applications in high-rise buildings with low loads, which can show its unique advantages. Low-temperature screw chillers are screw chillers whose temperature is controlled below 5 degrees. Antifreezes such as ethylene glycol and calcium nitrite are required to achieve low-temperature effects.

The low-temperature chiller with glycol and water mixture coolant is widely used in various industries and applications. Low-temperature chillers are very popular and important parts for model industries applications.

Product Features

1. The most efficient semi-hermetic compressor, the heart of the unit—imported high-quality screw compressors. Its 5:6 super-efficient screw rotor compressor is 20-30% more energy efficient than ordinary compressors. It is reliable, efficient, and easy to maintain. , Accurate capacity control, wide application range.
(1) The latest asymmetric rotor tooth profile;
(2) Four-stage or non-stage capacity control system;
(3) Built-in differential pressure type oil supply lubrication system;
(4) Low vibration and low noise.
2. The microcomputer controls the temperature accurately. The microcomputer controller of the unit adopts a large screen dot matrix LCD display, with a good all-Chinese man-machine dialogue interface to realize full-function automatic control. The LCD screen displays the working status of the machine in real time, and the accurate monitoring group is running at the best State, its light touch panel is well sealed, waterproof, dustproof, anti-corrosion, and has a long key life. Hierarchical and stepless energy control, used in general air conditioning systems, equipped with 100%, 75%, 50%, 25% hierarchical energy control systems. This ensures that the unit can achieve the maximum energy saving effect under partial load. However, if the water temperature needs to be accurately controlled, According to user requirements, all models can be equipped with stepless energy control.
3. High operating efficiency. The heat exchanger adopts high-efficiency bellows and the high-efficiency screw compressor ensures the high-efficiency operation of the unit. The most reliable protection and auxiliary components.
4. The screw chiller has the following components to prevent any malfunctions: compressor protection timer, overcurrent relay, compressor motor temperature sensor, anti-freeze thermostat, sight glass, oil heater, compressor reverse Phase protection relay, high and low pressure protection, exhaust high temperature protection, safety valve, easy to dissolve plug.

Low Temperature Chiller Application


Air Conditioning Project
Air-conditioning engineering is a broad field of refrigeration technology application. Optical instruments, precision measuring tools, textiles and other production workshops and computer rooms all require varying degrees of control of the temperature, humidity, and cleanliness of the environment; public buildings such as stadiums, conference halls, hotels, etc. need comfortable air-conditioning system.
Food engineering
Perishable food must maintain a stable low temperature environment during the entire circulation process from procurement or fishing, processing, storage, transportation to sales, in order to extend and improve the quality, economic life and value of food. This requires a variety of refrigeration facilities, such as cold processing equipment, refrigerated warehouses, refrigerated transport vehicles or ships, refrigerated vending counters, and so on.
Machinery and Electronics Industry
The oil pressure system of the precision machine tool uses refrigeration to control the oil temperature, which can stabilize the rigidity of the oil film and enable the machine tool to work normally. Low-temperature treatment of steel can improve the performance of the steel, increase the hardness and strength of the steel, and prolong the service life of the workpiece. Electronic equipment such as multiple communications, radars, and satellite ground stations also need to work at low temperatures.
Medical and health services
Plasma, vaccines and some special medicines need to be stored at low temperatures. Low temperature anesthesia, low temperature surgery, and cold compresses for high fever patients also require refrigeration technology.
Defense Industry and Modern Science
The performance of conventional weapons such as engines, automobiles, tanks, and artillery used in high-cold areas requires environmental simulation tests. Rockets and spacecraft also need to be tested under simulated high-altitude conditions, all of which require artificial refrigeration technology. Artificial rainfall also requires cooling. The application of screw chiller refrigeration technology is very extensive. With the development of the national economy, the progress of science and technology, and the continuous improvement of people's living standards, the development and application of refrigeration technology will move to new areas.
