Carrier KH45LE171 Filter Drier

The Carrier KH45LE171 Filter Drier is a critical liquid line component designed for high-capacity moisture and acid removal in commercial HVAC and refrigeration systems. Engineered for Carrier, Bryant, and Payne units, this bi-flow compatible drier utilizes a specialized desiccant bead core to protect the expansion valve and compressor from harmful contaminants. With a focus on high-side protection, the KH45LE171 liquid line filter drier ensures system stability by maintaining low pressure drops and preventing debris from circulating through the refrigeration circuit. For technicians performing HVAC system repairs or preventative maintenance, this 16-cubic-inch drier provides the exact OEM specifications required to maintain factory-grade performance and prevent premature component failure due to non-condensables.

Key Technical Benefits

• Optimized Moisture Absorption: High-density desiccant blend effectively traps water and minimizes acid formation within the refrigerant loop.
• Solid Core Filtration: Prevents particulate matter from clogging thermal expansion valves (TXV) or capillary tubes.
• Durable Construction: Steel shell design handles high-pressure environments typical of R-410A systems.
• Exact Fit Compatibility: Direct replacement for KH45LE171 ensures seamless installation during system evacuation and recharge.

Common Questions

Is the Carrier KH45LE171 bi-flow or uni-directional?
This specific model is primarily designed for liquid line applications in cooling-only or heat pump systems where high-capacity filtration is required for refrigerant flow management.

What refrigerant types are compatible with this drier?
The metallurgy and desiccant in the Carrier KH45LE171 are compatible with standard HFCs, including R-410A and R-22, as well as associated POE and mineral oils.

When should the liquid line filter drier be replaced?
Standard industry practice dictates replacing the HVAC filter drier whenever the system is opened for service, such as a compressor replacement or leak repair, to ensure the refrigeration cycle remains free of atmospheric moisture.
