Danfoss 023Z0037 Filter Drier

The Danfoss 023Z0037 Filter Drier, specifically the DCL 609S model, is a professional-grade hermetic liquid line filter drier designed for high-performance moisture and acid removal in refrigeration and air conditioning systems. Engineered with a specialized 80% molecular sieve and 20% activated alumina core, this unit is optimized for systems utilizing HCFC and CFC refrigerants, as well as mineral or alkylbenzene oils. The ODF solder connection ensures a leak-proof interface, while the high-density filter core maximizes particle retention without creating significant pressure drops across the liquid line. For technicians servicing systems where high adsorption capacity is critical, this solid core filter drier provides debris protection and prevents ice formation in expansion valves. The DCL series is built to withstand high working pressures, making it a reliable choice for maintaining internal system chemistry and preventing compressor burnout due to acid accumulation.

Key Benefits:

• Optimized Adsorption: Features a composite core for superior moisture capacity and acid neutralization in the liquid line.
• System Compatibility: Designed for use with HCFC and CFC refrigerants like R22, effectively protecting thermal expansion valves.
• Durable Construction: Hermetic design with a corrosion-resistant powder-painted finish rated for 500-hour salt spray tests.
• Flow Efficiency: Precision-engineered internal components allow for maximum flow rates with minimal refrigerant velocity loss.
• Debris Filtration: Mechanical filter pad removes particles down to 25 µm to ensure long-term capillary tube protection.

Common Questions:

What is the primary difference between the DML and DCL series?
While the DML focuses on 100% molecular sieve for HFCs, the DCL 609S contains activated alumina, making it the preferred choice for neutralizing acids in systems using mineral or AB oils.

Can the Danfoss 023Z0037 be installed in any orientation?
For optimal performance and oil return, it is recommended to install the filter drier in the liquid line with the arrow pointing in the direction of flow, preferably in a vertical position with flow downwards.

Is this filter drier compatible with POE oil?
While it can function, the activated alumina may slightly deplete certain additives in POE oil; for HFC/POE systems, a DML series drier is typically the standard specification.
