    Style A

    Style B

    Style C

    Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines. The vent on these steam traps is normally open, allowing condensate and air to flow out. The vent closes immediately when steam enters to prevent energy loss. Use them with heat exchangers, air-heating coils, and drip stations in steam lines.
    Style A—Style A has an inlet and an outlet on each side to connect inline or parallel steam and condensate lines.
    Style B—Style B has an inlet and an outlet on the same side to connect parallel steam and condensate lines.
    Style C—Style C has an inlet and outlet on opposite sides to connect inline steam and condensate lines.

    High-Flow Steam Condensate Pumps with Tank

    Move a higher volume of condensate than standard steam condensate pumps. Use these pumps in low-pressure steam systems to capture hot condensate and return it to your boiler or feed unit. They turn on when the tank is 2/3 full and turn off when condensate drops to 6" deep.

    Keep the water in your boiler at the proper level by pumping in condensate. Wire one of these pumps to the boiler’s controller and the float switch activates the pump to fill when water level gets too low. A safety valve connects to your facility’s water line to ensure the pump won’t run dry.
