Emerson Alco 047602 Filter Drier

As a seasoned tech, you know that keeping a system clean is the only way to prevent callbacks. The Emerson Alco 047602 Filter Drier, technically designated as model EK-052S, is a 5-cubic-inch liquid line filter drier engineered for high-performance moisture and acid remediation. This 1/4" sweat ODF unit features a premium compacted bead desiccant core—consisting of 75% molecular sieve and 25% activated alumina—specifically optimized for HFC and HCFC refrigerants such as R-410A, R-22, and R-404A. With a 20-micron filtration outlet pad, it ensures maximum particle retention without significant pressure drop. The steel shell is rated for a 680 PSI maximum working pressure and finished with corrosion-resistant epoxy powder paint, making it a reliable direct replacement filter drier for legacy part numbers like 96-TD052S, 450142-001, and 033199-0529. Its solid copper connections ensure easy brazing and a leak-free seal in residential and light commercial AC units.

Key Benefits for Contractors:

• Universal Refrigerant Compatibility: Approved for use with R-410A, R-134a, R-507, and POE oils used in Copeland compressors.
• High Acid Capacity: The charcoal-style desiccant blend captures harmful contaminants that lead to compressor burnout.
• Internal Filtration First: Designed to utilize the entire surface area of the desiccant bead for nonturbulent, cushioned flow.
• Rugged Construction: Shock-resistant steel shell provides durability in demanding field environments.

Yes, the Emerson EK052S is UL listed for 680 PSIG, meeting the high-pressure requirements for R-410A liquid line applications.

Can I use this for a burnout cleanup?
While this is a standard hermetic liquid line drier for moisture removal, its 25% activated alumina blend provides the acid neutralizing capacity necessary during routine maintenance or after minor system contamination.

What are the physical dimensions for fitment?
This 5 cubic inch filter drier features a compact design with 1/4" ODF sweat connections, making it ideal for tight spaces in condensing units or evaporator coils.
