UAR has specialized in manufacturing shell and tube heat exchangers, including evaporators, condensers, oil separators, etc.
For UAR evaporators, it can be divided into Falling Film Evaporator, Flooded Evaporator and Dry type Evaporator.
Falling Film Evaporator
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 defoaming 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.
Suitable for screw, centrifugal, magnetic bearing and other types of compressor.
Flooded Evaporator
Adopted 1.1mm thickness heat exchange tube specially designed for flooded evaporators and T-shaped spiral heat exchange tube greatly increases the heat exchange area.
The internal structure device has got a number of national patents.
The water passes through the heat exchange tube and the refrigerant flows in the she: the gaseous refrigerant produced as the result of heat exchange between the liquid coolant and the liquid refrigerant will go directly into the compressor which greatly improves the heat exchange efficiency.
Suitable for screw, centrifugal, magnetic bearing and other types of compressor. The difference between the out et water temperature and the evaporation temperature is nearly 0and the resistance along the way is small.
Dry-type Evaporator
A traditional type evaporator easy to control: the refrigerant evaporates in the tubes and the water cross flow in the shell High efficiency internal and externa grooved heat exchange tubes provide optimum heat exchange coefficient and service life.
Upgraded dry-type evaporator using spiral baffle plate to create cross flow of water Smaller in size and higher in heat exchange efficiency. Workable with all types of compressor.
