Heil Quaker ICP 1184693 TXV Kit

The Heil Quaker ICP 1184693 TXV Kit is a critical OEM thermal expansion valve replacement designed for high-performance sub-cooling control in R22 ductless and split systems. Rated for a 4.5-ton capacity, this externally equalized valve is manufactured by Danfoss to meet the exact pressure drop specifications required for Heil, Tempstar, and Comfortmaker evaporator coils. Professional technicians prefer this kit for its ability to maintain precise superheat across varying load conditions, preventing liquid slugging and protecting the compressor from premature failure. The 1184693 TXV features a 3/8-inch sweat inlet and a 3/8-inch thread outlet, ensuring a robust, leak-free connection when installed following standard HVAC mechanical codes. Replacing an older ICP 1173165 or a fixed-orifice piston with this R22 TXV Kit significantly improves system efficiency and seasonal energy ratings by optimizing the refrigerant flow-rate based on real-time evaporator temperature and pressure.

Key Benefits:

• Precise Superheat Regulation: Maximizes heat transfer efficiency by accurately metering R22 refrigerant flow into the evaporator.
• OEM Compatibility: Genuine International Comfort Products part ensures a perfect fit for Heil Quaker, Tempstar, and Arcoaire units.
• Compressor Protection: Actively prevents liquid refrigerant from returning to the suction line, extending the life of the HVAC system.
• Complete Installation Kit: Includes the Danfoss expansion valve, bulb mount strap, teflon ring, and zip ties for a professional-grade repair.
• High Pressure Rating: Built to withstand a maximum working pressure of 660 psig, suitable for R22/R407C applications.

Common Questions:

Can I use this TXV kit to convert a piston-metered system to R22?
Yes, the 1184693 is frequently used as a piston-to-TXV converter kit to enhance performance in older R22 indoor coils, provided the coil is rated for the 4.5-ton capacity.

Where should the sensing bulb be mounted for optimal flow?
The bulb must be securely strapped to a horizontal section of the suction line, ideally at the 4 or 8 o?clock position, and must be fully insulated to sense internal gas temperature accurately.

Does this kit work with R407C refrigerant?
Yes, this Danfoss valve is technically rated for both R22 and R407C, making it a versatile choice for modern drop-in refrigerant retrofits.
