Introduction
Stainless steel, hermetically tight solder version high connection strength high corrosion resistance
capillary tube joints of high strength and vibration resistance
Lar-welded, stainless steel diaphragm element optimum function long diaphragm life high pressure resistance Adjustable tting accurate tting fi ne tuning possible Low p-band Low hysteresis
TUH & TCHE have an advanced fi lter/strainer design
TUH/TCHE/TGHE c apacity r egulators a dapt c ompressor capacity to actual evaporator load in applications operating at an evaporating temperature of around 0°C. TUH/TCHE/TGHE valves are typically ud in applications such as: Air driers Water chillers
Fitted in a bypass between the high and low-pressure sides of the air-drier system, T UH/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 rves as a rervoir for the charge. However, it is recommended that the bulb be mounted in a location where temperature variation during operation is limited (e application drawings).

Setting
The valve is t to start opening at an evaporating temperature of +2°C/+36°F . The tting can be changed by turning the tting spindle. The temperature at which the valve starts opening is incread by turning the spindle anti-clockwi and decread by turning the spindle clockwi.Specifi cally designed for hot gas applications. All valves react only on to suction pressure variations.
