Carrier KH45LE120 Filter Drier Full Product Description

Product Overview The KH45LE120 filter drier is a critical OEM replacement component exclusively designed for Carrier screw and centrifugal water-cooled chillers. Installed on the refrigerant liquid pipeline, it integrates drying, acid neutralization and multi-stage impurity filtration in one single unit, solving common refrigeration system faults caused by moisture, acid residue, metal debris and solid particles. This model strictly follows Carrier's original production standards, with consistent outer size, thread specification and internal filler as the factory-original part, allowing direct plug-and-play replacement without any pipeline modification.

Core Technical Parameters

Model: KH45LE120

Brand Match: Carrier Chiller

Connection Thread: 7/8"-22UNF

Max Working Pressure: 500PSIG (3.5MPa)

Operating Temperature Range: -30℃ ~ 120℃

Compatible Refrigerants: CFC, HCFC, HFC refrigerants including R134a, R22, R407C, R410A

Internal Medium: High-efficiency molecular sieve + acid neutralizer + stainless steel filter screen

Flow Direction: Fixed one-way flow, marked clearly on the tank body to avoid reverse installation

Key Functional Advantages First-class moisture absorption capacity: The built-in high-density molecular sieve rapidly captures free water inside the refrigerant loop, completely eliminating ice blockage at expansion valves and capillary tubes under low-temperature working conditions. Powerful acid removal performance: Special neutralizing material reacts with acidic substances produced by refrigerant decomposition and oil aging, preventing chemical corrosion on copper pipes, bearings and compressor cylinder walls. Multi-layer precision filtration: Multi-grade stainless steel filter screens intercept metal shavings, welding slag, pipeline rust and other hard particles, avoiding scratches on compressor scrolls, bearings and expansion valve throats. Superior pressure resistance & leak-proof performance: Thickened seamless steel tank with electrostatic anti-rust paint, passed strict air tightness testing, stable performance under long-term high and low temperature cycling. Universal compatibility: Suitable for all mainstream Carrier liquid chiller units, widely used in commercial central air conditioning, industrial process cooling, shopping mall and hotel refrigeration systems.
