200kw anti-corrosion low temperature water cooled screw chiller with -12C outlet water temperature

A 200KW low temperature calcium nitrite calcium nitrate chiller system with an anti-corrosion evaporator is designed for cooling applications that require a temperature as low as -12°C. The chiller utilizes a screw compressor refrigeration system, which is known for its efficiency and reliability in industrial cooling systems.

The chiller system is specifically designed to handle the cooling requirements of calcium nitrite and calcium nitrate processes. These processes often require a low-temperature environment to maintain the stability and quality of the products.

The evaporator of the chiller is made of nickel white copper, which is chosen for its anti-corrosion properties. This is important because the chiller operates at low temperatures and comes into contact with the calcium nitrite and calcium nitrate solutions, which can be corrosive.

The chiller system is capable of maintaining a stable and precise temperature control, ensuring optimal performance and product quality throughout the cooling process. It is also designed for energy efficiency, reducing operational costs in industrial applications.

Overall, the chiller system provides a reliable and efficient solution for low-temperature cooling in processes involving calcium nitrite and calcium nitrate, with special attention to anti-corrosion measures to ensure long-term durability and performance.

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.
