Regolatori di bypass gas caldo - TUH, TCHE, TGHE

TUH / TCHE / TGHE

TUH, TCHE and TGHE capacity regulators adapt compressor capacity to actual evaporator load in applications operating at an evaporating temperature of around 0 °C. TUH, TCHE and TGHE valves are typically used in applications such as:
• Air driers
• Water chillers
Fitted in a bypass between the high and low pressure sides of the air-drier system, TUH, TCHE and 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 and 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.
