Coalescing Removal Separators – CRS

The Bell & Gossett CRS coalescing-style air and sediment separator is available for use in any HVAC system. Its internal coalescing media helps break entrained air and suspended solids out of your system fluid. The CRS efficiently removes these contaminants, therefore improving heat transfer capabilities. This results in lower energy costs while protecting pumps, boilers and other components, and extending the life of your system. With its wide variety of sizes, connections and configurations, the Bell & Gossett CRS is a great solution for any HVAC application.

CRS separators are available in a number of models to best fit your system requirements. Models are available for air-only, sediment-only, and air/sediment combo separation, with options for removable or non-removable coalescing media, and for standard or high velocities. All CRS models are designed, constructed, inspected, and stamped per Section VIII, Division 1 of the ASME code for 150 psi (1,034 kPa) maximum working pressure and 450°F (232°C) maximum working temperature. Higher pressures and temperatures are available upon request. Models are available in sizes 2″ through 36″ with NPT (2″ – 4″ only), flange, or groove end connections.
