Bell & Gossett enhanced air separators (EAS), including the EASB-junior model, the IAS in-line air separators, and the Rolairtrol commercial air separators, remove entrained air from hot water heating systems, thereby providing efficient transfer of heat throughout the system. By removing entrained air within the water, you increase heat transfer, save energy, and have increased heating comfort.
Bell & Gossett air vents are float type automatic air vents that are designed to vent troublesome air from hydronic heating systems. Bell & Gossett offers small-sized models, high capacity models, and coin-operated vent models of air vents. Air vents come in 1/8", 1/2", and 3/4" pipe connections, as well as, cast iron, brass, and steel construction.
Bell & Gossett is a premier manufacturer of pumps, including in-line centrifugal (available in maintenance-free, close-coupled, and split-coupled) pumps, base-mounted centrifugal pumps, foot-mounted centrifugal (or end suction) pumps, double suction (or split-case) pumps, in-line booster pumps, multi-stage pumps, heat exchangers and tube bundles, vertical turbine pumps, and small circulator pumps, as well as, their related accessories and repair parts.
Bell & Gossett offers various control valves, including Flo-Control valves, Hydrotrol flow control valves, Monflo fittings, and Comfort-Trol zone valves. All of these Bell Gossett valves work in their own unique way to control the flow of water in hot water heating systems. Zone control valves open and close to distribute hot water to different heating zones. Zone control valves are used for either continuous or intermittent cycling operation of the system pump. The valve design permits easy replacement of the seal gland without isolating the valve or draining the system.
Bell & Gossett expansion tanks absorb the force of thermal expansion in hydronic heating and potable domestic water systems. The butyl diaphragm separates system water from the air in the tank thereby preventing water-logging problems. Series HFT tanks are for standard hot water heating systems while PT tanks are for potable domestic water systems, both have a maximum working pressure of 100 psi and a maximum operating temperature of 240°F. Series PT tanks use a polypropylene liner to protect the water from contaminants. Special ASME designated Series PT tanks can also be ordered.
Bell & Gossett offers shell and tube heat exchanger and replacement tube bundles for both steam (SU) and hot water (WU) applications available in a wide range of sizes. Steam or hot water flows through the copper heat exchangers tubes to heat water. Heat exchangers are available in straight tube and u-tube designs.
Bell & Gossett suction diffusers are an angle-pattern, flow-straightening fitting that combines a diffuser/strainer, orifice cylinder, and full length straightening vanes to provide ideal flow conditions for the pump suction. Suction diffusers are available in sizes from 1-1/2'' to 10'' in NPT, flanged, and grooved connections. They are available in pressures up to 175 psi. These suction diffusers come standard in cast iron bodies with steel straightening vanes, orifice cylinders, and bronze strainers. Stainless steel straightening vanes and orifice cylinder are optional.
Bell & Gossett valves and accessories for hot water heating systems available include balancing valves, isolation valves, pressure reducing and relief valves, sediment separator valves, pump suction diffuser valves, air separators, air vents, triple duty valves, and more.
