Rcd KH43LG072 Heat Pump Filter Drier R-410A

Product Description

The RCD KH43LG072 is a heat pump filter drier designed for use with R-410A refrigerant systems. Filter driers serve a dual purpose in a refrigerant circuit: they remove moisture and contaminants that can cause acid formation, copper plating, and compressor damage. This drier is an OEM-specification component intended for heat pump applications and is installed by licensed HVAC technicians during system commissioning, refrigerant line service, or after a compressor replacement.

The KH43LG072 is suited for heat pump systems charged with R-410A refrigerant. R-410A operates at higher pressures than legacy refrigerants, so filter driers used in these systems must be rated and designed specifically for R-410A service. This drier is referenced as a Carrier HVAC equipment component, making it applicable to heat pump installations in residential settings where Carrier equipment is serviced or maintained.

Key Features

• Designed specifically for R-410A refrigerant service
• Removes moisture and particulate contamination from the refrigerant circuit
• OEM-specification replacement for Carrier heat pump systems
• Protects compressor and expansion components from acid and debris damage
• Suitable for installation on liquid or suction line per system design

Compatibility

Referenced as an OEM component for Carrier HVAC heat pump equipment charged with R-410A refrigerant.

Installation Notes

Filter drier replacement is performed by EPA Section 608 certified HVAC technicians. Recover all refrigerant from the system before cutting or unbrazing any refrigerant lines. Driers should be replaced any time a system is opened to atmosphere or after compressor failure to prevent moisture and acid contamination from circulating through the circuit. Braze connections using dry nitrogen flowing through the line set to prevent internal oxidation scale.
