Bimetallic Steam Trap For Superheat Conditions – SH-1600 Series

Armstrong’s SH-1600 Series Bimetallic Steam Traps operate in superheat conditions, by the effect that rising temperature has on the bimetallic elements. How it Operates: At start-up the valve is wide open allowing a large volume of non-condensables and cold condensate to be removed from the system When the trap reaches...

Product

Thermostatic Air Vent – TTF Series

Armstrong offers thermostatic air vents for positive venting of air and other non-condensable gases from steam in chamber-type heat-transfer equipment. Typical applications include jacketed kettles, retorts, vulcanizers, jacketed sterilizers or other contained equipment where air could accumulate in remote areas of the steam chamber and reduce heat-transfer capacity. These vents...

Product

Noiseless Heater – Model MS-6

The use of hot water is indispensable in food processing, cleaning, and plating operations. Although the simplest and most efficient way to provide the water is by direct steam sparging, such a format often results in vibration and noise caused by steam blowing into the water tank. These problems can...

See-Through Free Floating Lever Drain Trap – 1-LDC

A free floating mechanism in the 1-LDC needs no electricity to operate. The 1-LDC discharges automatically only when liquid is present. That means no air loss as with timed devices that open even when liquid is not present. Moisture in a compressed air system causes problems. Getting the water out—automatically,...
