Tangential Air Separators

Sediment Removal Separator – SRS

The Bell & Gossett Sediment Removal Separator (SRS) is a patented centrifugal style air and sediment separator for use in any HVAC system. Its 3-to-1 body diameter to nozzle diameter ratio slows the fluid velocity to allow entrained air and suspended sediment to come out of solution, while its tangential inlet and outlet nozzles induces centrifugal fluid flow. This centrifugal flow creates a low pressure vortex in the center of the tank where entrained air can come out of solution and float to the top of the tank and suspended sediment can sink to the bottom. In addition, the SRS features an extended collection cap at the bottom of the tank where sediment can collect without the risk of being pulled back into the system by the exiting fluid. These impurities can then be easily removed via an air vent or connection to an expansion tank and a blowdown valve.

Contaminants such as air and suspended sediment can lead to diminished heat transfer, higher energy costs, damage to your system components, and increased system noise. By removing them you can lower the cost to operate your system, extend the life of your components, and provide better comfort to your building occupants.

All SRS models are designed, constructed, inspected, and stamped per Section VIII, Division 1 of the ASME code for 125 psi (862 kPa) maximum working pressure and 350°F (177°C) maximum working temperature. Higher pressures and temperatures are available upon request. Models are available in sizes 3″ through 36″ and are available with NPT (3″ only), flange, or groove end connections.
