Copeland Comfort Control (Alco) 048229 Filter Drier

The Copeland Comfort Control (Alco) 048229, also identified as the Model EK759S, is a high-capacity liquid line filter drier designed for demanding commercial refrigeration and HVAC applications. Built with a 75 cubic inch desiccant volume, this unit provides exceptional moisture, acid, and contaminant removal to protect the compressor and expansion valves. The 1 1/8" sweat (ODF) connections ensure a secure, leak-proof fit in large-scale systems, while the 20-micron filtration rating captures fine particulates that can cause mechanical wear.

Engineered for modern high-pressure environments, this filter drier supports a maximum working pressure of 680 PSI, making it compatible with R-410A and other high-pressure refrigerants. The Alco EK series is known among technicians for its premium compacted bead desiccant, which prevents attrition and ensures consistent flow with minimal pressure drop. Whether you are performing a seasonal teardown or a compressor burnout cleanup, the 048229 EK-759S offers the high-volume capacity required for commercial HVAC filtration and long-term system stability.

• High-Capacity Desiccant: 75 cu in volume provides superior acid and moisture buffering in high-tonnage systems.
• Superior Filtration: 20-micron internal filtration media protects sensitive components from solid contaminants.
• High Pressure Rating: Rated for 680 PSI, suitable for R-410A and contemporary refrigeration cycles.
• Service Ready: 1 1/8" ODF sweat connections allow for standard brazing techniques in the field.
• Universal Compatibility: Compatible with POE, PAG, and mineral oils used in commercial cooling.

What is the difference between the 048229 and the EK-759S?
These parts are identical. 048229 is the specific Emerson/Copeland SKU, while EK-759S is the model designation used across the Alco brand for this 75 cubic inch, 1 1/8" sweat drier.

Can this drier be used on the suction line?
No, this is a dedicated liquid line filter drier. For suction line applications or burnout cleanup on the low side, a specialized suction filter drier must be used to avoid excessive pressure drop.

Is this unit compatible with high-pressure refrigerants like R-410A?
Yes, the 680 PSI maximum working pressure meets the requirements for R-410A systems and other high-pressure applications where standard 500 PSI driers may be insufficient.
