Energy-Saving Iron Steam Traps



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 has an inlet and an outlet on each side to connect inline or parallel steam and condensate lines.
Style B has an inlet and an outlet on the same side to connect parallel steam and condensate lines.
Style C has an inlet and outlet on opposite sides to connect inline steam and condensate lines.

Stainless Steel Steam Traps

Made of 316 stainless steel, these steam traps have excellent corrosion resistance. Also known as thermostatic steam traps, they increase the efficiency of your radiator by venting cool air. They open and close based on temperature. Use with convection heaters, drip lines, and risers. Steam traps should be installed with the outlet pointing down.

Sanitary Energy-Saving Stainless Steel Steam Traps


When close to steam temperature, these traps—also called thermodynamic steam traps—release condensate from steam lines to save energy in food, pharmaceutical, and other sanitary environments. Made of 316 stainless steel, they stand up to frequent washdowns with harsh cleaners and sanitizers to reduce the risk of bacteria growth. They have quick-clamp tube fittings and a threaded cap, which are easy to remove for cleaning or access to your line.
Often used while equipment is operating at high pressures and temperatures, these steam traps don’t have plastic or rubber seals that can degrade over time. The lack of seals, however, means they may not last as long as other steam traps. Install these steam traps horizontally.

Sanitary Stainless Steel Steam Traps

Suitable for food, pharmaceutical, and other sanitary environments, these steam traps are made of 316 stainless steel with a Viton® fluoroelastomer O-ring to stand up to frequent washdowns with harsh cleaners and sanitizers. They have a smooth 20Ra interior finish—smoother than most food and dairy applications require—and a self-draining design to reduce the risk of bacteria growth. They also have quick-clamp tube fittings, which are easy to remove for cleaning and access to your line. The O-ring is FDA compliant for direct contact with food.
Use these steam traps to increase the efficiency of your radiator by venting cool air. Also known as thermostatic steam traps, they automatically open and close based on temperature. Install them with their outlet pointing down.
