Bohn 4600c Filter Drier Liquid Line 3/8 Odf R744 R290

Product Description

The BOHN 4600c is a liquid line filter drier designed for refrigeration systems operating on R744 (CO2) or R290 (propane) refrigerants. Filter driers remove moisture, acid, and contaminants from the refrigerant circuit, protecting compressors, expansion devices, and other system components from damage. With a 3 cubic inch desiccant volume and a 3/8 ODF connection, this drier is sized for commercial refrigeration equipment where natural refrigerants are specified. Installation is typically performed by licensed refrigeration technicians during system commissioning or as part of a compressor or refrigerant charge replacement service.

This drier is suited for commercial refrigeration applications using low global warming potential refrigerants, specifically R744 and R290. These refrigerants are increasingly common in supermarket display cases, walk-in coolers, and other commercial appliance systems where Heatcraft evaporator coils and related components are installed. The 3/8 ODF connection fits standard copper liquid line tubing used in these configurations.

Key Features

• Compatible with R744 (CO2) and R290 (propane) natural refrigerants
• 3 cubic inch desiccant volume for effective moisture and acid removal
• 3/8 ODF connection for standard copper liquid line installations
• Liquid line design protects downstream expansion devices and metering components
• Sourced as a Heatcraft commercial appliance parts and accessories component

Compatibility

Designed as an OEM-style replacement filter drier for Heatcraft commercial refrigeration equipment requiring a liquid line drier rated for R744 or R290 refrigerants.

Installation Notes

Filter drier installation on R744 or R290 systems must be performed by a licensed refrigeration technician familiar with the pressure and flammability characteristics of these refrigerants. Recover all refrigerant and isolate the system before cutting into the liquid line. Braze the drier into the liquid line with the flow arrow oriented in the direction of refrigerant flow, and pressure-test all joints before recharging. Replace the filter drier any time the system is opened or when moisture contamination is suspected.
