Carrier KH45LG141 Drier

The Carrier KH45LG141 is a high-capacity suction line filter drier specifically engineered for HVACR systems requiring robust protection against contaminants. Designed with 7/8" ODF sweat connections, this SLD13-7SVHH model is essential for technicians performing a compressor burnout repair or a system cleanup. By utilizing a specialized desiccant blend, it effectively captures moisture, acid, and solid particulate matter, preventing premature failure of the new compressor. This OEM Carrier part is rated for high-pressure applications, including R-410A refrigerant systems, and features a 15-cubic-inch desiccant volume to handle significant system contamination. Its uni-directional flow design ensures maximum filtration efficiency with minimal pressure drop, maintaining the performance standards of Carrier, Bryant, and Payne equipment. Integrating this drier into your suction line installation provides the critical secondary defense needed to ensure long-term system reliability after a major component failure.

• Superior Acid Neutralization: High-capacity desiccant core specifically formulated to remove harmful acids and moisture following a refrigerant system cleanup.
• Optimized Flow Characterisitcs: Large internal surface area minimizes pressure drop across the suction line, protecting system capacity.
• Durable Construction: Solid copper 7/8" ODF connections and a powder-coated steel shell resist corrosion and simplify the brazing process for field technicians.
• Broad Compatibility: Genuine replacement part designed for use with a variety of Carrier-family residential and commercial split systems.

When should I install a suction line drier versus a liquid line drier?
While liquid line driers are standard for moisture control, a suction line filter drier like the KH45LG141 is typically reserved for protecting the compressor directly after a burnout or when significant debris is suspected in the lineset.

What is the proper orientation for installing the KH45LG141?
This is a uni-flow drier. Always verify the flow arrow on the shell points toward the compressor inlet. It can be mounted vertically or horizontally, though vertical mounting with downward flow is often preferred to prevent oil trapping.

Can this be used with R-22 and R-410A systems?
Yes, this HVAC filter drier is compatible with most modern refrigerants, including R-410A and R-22, provided the 7/8 inch connection matches your line size and the system capacity is within the 15 CU rating.
