In an HVAC system, any contaminants in the unit can prevent the refrigerant from doing its job correctly, and cause damage to the equipment. That’s why it’s important that those foreign contaminants stay out.

Bell & Gossett, a Xylem brand, recently announced an expansion of its CRS coalescing-style air and sediment separator product line. The extended CRS line — available for use in any HVAC system — helps break entrained air and suspended solids out of system fluid, efficiently removing these contaminants and improving heat transfer and energy efficiency.

“This expansion to our CRS product line provides our customers next-level adaptability for commercial systems,” says Chris Kerback, Bell & Gossett product line manager, Engineered Specialties group. “Now with even greater variety of sizes, connections and configurations, the Bell & Gossett CRS line improves contaminant control in any HVAC system design.”

With lower energy use and a durable design, the CRS helps protect pumps, boilers and other components, improving and prolonging the life of a system. The separator’s internal coalescing media efficiently removes up to 100% of fluid contaminants — including entrained and free air and suspended solids out of HVAC systems, improving heat transfer capabilities and resulting in energy efficiencies.

Benefits of the product include lifting lugs to make moving and installing easier, a threaded connection that provides an optional air vent or can be used for connection to an expansion tank, an optional skim valve to move large volumes of air during system fill, stainless steel coalescing media that helps break the surface tension within the system fluid to release air and allow bubbles to rise to the top of the tank for removal or direct to the expansion tank, and a tank body design that is twice as large as the inlet and outlet nozzles, providing a reduction in fluid velocity, easing the removal of entrained air and suspended solids.

Separators are available in a number of models to best fit a system’s requirements. Models are available for air-only, sediment-only and air/sediment combo separation, with the option for a removable or non-removable coalescing media, and for standard or high velocities. Models are available in 2- through 36-inch sizes, with 2- to 4-inch flange or groove end connections. They have a max 150 psi and 450 degree F maximum working temperature. 847-966-3700;
