The secondary refrigerant passes through the heat exchange tube, the refrigerant flows in the shell side and completely immerses the heat exchange tube, and evaporates outside the heat exchange tube after absorbing heat.

Double skin air handling unit are widely used in precision machinery and electronics, medical instrument biochemical laboratories, food valuable parts and factory production lines.

Our falling film evaporator are compact and easy to install, suitable for chillers with multiple compressor systems.

*Liquid sprayed from above is to form a thin film on the surface of the heat exchange tube to obtain the best heat transfer effect. *The liquid separation and deforming device is national patented. *With no superheat requirement of refrigerant vapor the evaporation temperature can be greatly increased. *Achieve 30% higher heat transfer coefficient and 35% less refrigerant charge volume than flooded evaporators. The spray type evaporator is suitable for screw, centrifugal, magnetic bearing and other types of compressor.

316L stainless steel water to water shell and tube heat exchanger can be customized by UAR(Guangzhou United A/C & R CO. Ltd . The shell side and tube side of the shell and tube heat exchanger are made of 316L stainless steel, which is suitable for various water quality and corrosive environments.

R1234ze shell and tube evaporator and condenser has been developed by UAR recently, which has helped chiller maker factory to increase the efficiency and calculate the accurate heat transfer.

Chiller shell and tube evaporators are specially designed for systems such as air conditioning systems, cooling systems, and heat pump machining. Its convenient maintenance, high heat transfer performance, is widely used in chemical processes, power plants, refrigeration machinery and other occasions. Please see above flooded evaporator diagram.

Heat exchanger, which is a main part of air conditioner and refrigerant equipment, quality and performance are more value to chiller manufacturer. A matched heat exchanger with excellent quality not only benefits manufacturers, but also creates a cool and comfortable environment for user.

UAR custom-made Shell and Tube  heat exchangers , Titanium and Stainless heat exchangers ,  extensive use, for energy conversion systems are designed for high-temperature and high-pressure environments.
