Stainless Steel Capacity Regulation Valves

Type TUH and TCHE capacity regulators adapt compressor capacity to actual evaporator load for applications operating at an evaporating temperature near 32^oF (0

^oC). They are suitable for applications such as air dryers, water chillers, ice machines and chillers for electronic component cooling. Offered in nominal capacities from 0.5 to 2.2 TR (R404A), the valves are optimized for use with R134a, R404A/R507, and R407C. When placed in a bypass between the high and low pressure sides of the system, these valves maintain suction pressure by bypassing hot or cool gas from the high pressure side. Type TUH has internal pressure equalization, and Type TCHE is externally equalized. Both open on a decrease in suction pressure at the valve outlet. The TCHE has external equalization and opens directly on a decrease in the suction pressure at the compressor. The capacity regulators for hot gas bypass are made of stainless steel with the bimetal connections.

Avoiding scale, corrosion and microbiological growth — all of which diminish effective heat transfer — is the focus of any water treatment approach for water-contacted process heating and cooling equipment.
