Emerson Alco 059874 Filter Drier

The Emerson Alco ADK-032 (059874) is a solid-core liquid line filter drier engineered for critical moisture and acid removal in high-pressure refrigeration systems. Featuring a 3 cubic inch desiccant volume and a 1/4" flare connection, this unit utilizes a 40-micron internal filtration pad to protect expansion valves and solenoids from particulate contamination. Designed for compatibility with HCFC, HFC, and CO2 refrigerants, its high-capacity desiccant blend ensures maximum water capacity and acid neutralizing performance. With a 680 PSI maximum working pressure and a durable powder coat finish, this filter drier maintains system integrity under harsh operating conditions. This compact drier is a standard choice for HVAC service technicians performing maintenance on small tonnage systems where reliable system dehydration and contaminant sequestration are required to prevent premature compressor failure and oil acidification.

• High-Moisture Capacity: Optimized desiccant blend provides superior water removal to prevent ice formation at the expansion valve.
• 40-Micron Filtration: Integrated outlet pad captures fine metal shavings and sludge to protect sensitive metering devices.
• Universal Refrigerant Compatibility: Suitable for use with R-22, R-134a, R-404A, and R-410A systems.
• Robust Construction: 680 PSI rating and corrosion-resistant finish ensure reliable performance in commercial refrigeration environments.
• Secure Connections: 1/4" SAE flare fittings provide a reliable seal and simplified field replacement.

Common Questions

What is the maximum working pressure for the ADK-032?
This model is rated for a Maximum Working Pressure (MWP) of 680 PSI, making it suitable for high-pressure systems including R-410A.

Can this filter drier be used for bi-directional flow?
