Copeland Comfort Control (Alco) 048224 Filter Drier

The Copeland Comfort Control Alco 048224 Filter Drier, also identified as the Model EK417S, is a high-capacity liquid line filter drier engineered for demanding commercial and industrial refrigeration systems. Featuring a large 41 cubic inch desiccate volume, this unit provides exceptional moisture removal and acid neutralization capacity, essential for protecting the compressor from premature failure. The 7/8" ODF sweat connections ensure a secure, leak-free braze joint, while the internal 20-micron filtration pad prevents particulate matter from clogging expansion valves or capillary tubes. Designed to handle high-pressure environments, it maintains a 680 PSI maximum working pressure, making it fully compatible with R-410A, R-22, and other common refrigerants. As a direct HVAC replacement part for the 417S, DHY0170, and 401614, this drier utilizes a premium beaded desiccant to maximize surface area contact without significant pressure drop, ensuring the system maintains peak thermal efficiency and long-term reliability in the field.

Key Benefits for Technicians

• Superior Desiccant Blend: Optimizes the removal of moisture, organic acids, and inorganic acids to maintain system chemistry.
• High Pressure Rating: Rated for up to 680 PSI, allowing for safe integration into modern high-pressure refrigerant circuits.
• Direct OEM Compatibility: Serves as a precise replacement for Alco 048224, 417S, and DHY0170, reducing downtime during retrofits.
• 20-Micron Filtration: Provides fine particulate capture to protect sensitive downstream components like TEVs and solenoids.
• Durable Construction: Shock-resistant steel shell designed to withstand mechanical vibration and thermal cycling common in HVACR applications.

Common Installation and Compatibility Questions

What is the flow capacity for the EK417S drier?
The EK417S is designed for high-tonnage systems; typically, at a 1 PSI pressure drop, it handles approximately 14.9 tons for R-134a and 15.1 tons for R-410A, depending on liquid temperature.

Can this filter drier be used in bidirectional heat pump lines?
No, the Copeland Alco EK series is a standard liquid line filter drier intended for one-way flow. For heat pump applications, a dedicated biflow drier should be used to prevent trapped debris from flushing back into the system.

Is the 7/8" sweat connection compatible with standard ACR tubing?
Yes, the 7/8" ODF connections are sized to receive 7/8" OD copper tubing, facilitating standard brazing procedures with silver solder or Phos-Copper alloys.
