TUH/TCHE/TGHE capacity regulators adapt compressor capacity to actual evaporator load in applications operating at an evaporating temperature of around 0° C.
Fitted in a bypass between the high and low-pressure sides of the air-drier system, TUH/TCHE/TGHE maintain compressor suction pressure by injecting hot gas/cool gas from the high-pressure side.
TUH has internal pressure equalisation and opens when pressure drops at the valve outlet. TCHE/TGHE have external pressure equalisation and open directly when compressor suction pressure drops.
For all types, the bulb only serves as a reservoir for the charge. However, it is recommended that the bulb be mounted in a location where temperature variation during operation is limited.
