- Part Number / Model: AACE 3 SW195 30IN 3/8 X 1/2 ODF S/T
Product Details
The externally equalized design ensures accurate superheat sensing even when evaporator pressure drop is a factor, improving system efficiency and reliability. The integrated internal check valve simplifies installation in heat pump systems by eliminating additional components and reducing potential leak points. The 30″ capillary tube provides ample flexibility for bulb positioning on the suction line.
Applications
- Residential and light commercial split-system air conditioners
- Heat pump systems requiring reverse-cycle refrigerant flow
- R410A refrigeration and cooling systems rated at 3-ton capacity
- Replacement TXV for systems requiring MOP 195 PSI protection
