Heat Exchanger Unit Heaters

Extra heavy-duty (including heavy gauge steel construction) to meet the most demanding service and long life requirements for rugged industrial applications. The FR Series heaters are specifically designed for steam applications that may be subject to freezing conditions and are of particular value for outdoor applications. They gain their resistance to frost damage through the use of rectangular top and bottom headers. Explosion-proof models suitable for hazardous locations are available on a custom order.
