Lennox 11W02 Kit
For field technicians and mechanical contractors maintaining Lennox split systems, the Lennox 11W02 Kit provides the necessary components for a precise .073 RFC kit conversion or replacement. This piston orifice assembly kit is engineered as a fixed-bore metering solution, specifically calibrated to 0.073 inches to regulate refrigerant flow between the liquid line and the evaporator coil. Unlike variable expansion valves, the Lennox 11W02 .073 RFC operates as a restrictor field control device, ensuring a constant flow rate that is critical for meeting OEM superheat specifications in HFC-410A refrigerant applications. As a genuine HVAC replacement part, this 11W02 assembly eliminates the guesswork in refrigerant metering, providing consistent pressure equalization across the system during the off-cycle. Whether you are performing a new installation or a routine service call, utilizing this factory-spec metering device is essential for protecting the compressor from liquid slugging while maintaining optimal heat transfer efficiency across the lanced fins of the indoor coil.
Key Benefits- Precise Metering: Features a factory-calibrated 0.073-inch bore size for accurate refrigerant flow management.
- OEM Compatibility: Designed specifically for Lennox HVAC equipment, ensuring seamless integration with existing liquid line setups.
- System Protection: Helps prevent improper evaporator flooding, maintaining correct superheat levels to safeguard the compressor.
- Simplified Service: Operates as a reliable fixed orifice, reducing moving parts compared to TXV systems for long-term field stability.
What is an RFC kit in Lennox systems?
An RFC (Restrictor Field Control) kit is the Lennox-specific designation for a fixed-bore metering device or piston. It is used to create a precise pressure drop in the refrigerant line before it enters the evaporator.
What refrigerant is the 11W02 kit compatible with?
This kit is intended for use in systems matched for HFC-410A, though always verify the specific unit nameplate and charging charts for orifice sizing requirements.
Can I use this 11W02 kit to replace a TXV?
This is a fixed-metering device. If your system was originally designed for or upgraded to a Thermostatic Expansion Valve (TXV), you must ensure the system is properly converted back to a fixed-orifice configuration according to the manufacturer’s installation instructions.
