Trane DHY01452 Bi-Flow Filter Drier 16 Cu. In. 3/8" ODF 5.7-Ton Heat Pump

The Trane DHY01452 is an OEM bi-flow filter drier engineered for heat pump condensers. Sold under the Service First brand (model DCB163S), this drier removes moisture and contaminants from refrigerant lines to protect compressor components and maintain system efficiency. Its bi-flow design allows refrigerant to pass through in either direction, making it ideal for heat pump applications that reverse refrigerant flow between heating and cooling cycles.

Key Features:

• Capacity: 16 cubic inches (16 Cu. In.)
• Connection Size: 3/8" ODF (Outside Diameter Flare)
• System Capacity: Rated up to 5.7 tons
• Refrigerant Compatibility: Approved for use with R-410A and R-407C refrigerants
• Oil Compatibility: Compatible with both mineral oil and POE (polyolester) oil refrigerants
• Construction: Durable steel housing for long-term reliability
• Design: Bi-flow configuration supports heat pump systems with reversing refrigerant flow
• OEM Part Numbers: DHY01452 / DCB163S

This filter drier is a genuine OEM replacement part compatible with American Standard, RunTru, and Trane-brand heat pump condensers. It is typically replaced as part of a sealed system repair alongside the compressor and/or evaporator to ensure a clean, moisture-free refrigerant circuit.
