Introduction of Termal Thermostatic Expansion Valve:
Thermostatic expansion valve regulate the flow rate of refrigerant intoevaporators according to its degree of superheat. Both the internal equalizerand external equalizer systems are furnished, especially, the external equalizertype efficiently eliminates the influence resulted from the loss evaporatorpressure.
The interchangeable orifice is easy to store and maintain, making theequipment to match with the system with ease. Wide range of evaporatortemperature: -40°C~+10°C
