Water Heaters #5216413

Over-the-Side immersion heaters are designed for installation in the top of the tank with the heated portion directly immersed along the side or at the bottom ("L" shaped). Over the Side immersion heaters take up little space, eliminate the need for tank penetrations, are easily removed for service, and provide ample working space inside the tank. Custom configured elements evenly distribute heat by direct contact in numerous applications, including acid and alkali solutions. Many units are Teflon coated and low watt density for protection against aggressive liquids.

Screw plug immersion heaters consist of tubular elements in a threaded hex plug. Some models are provided with a thermowell for the temperature control sensor and a variety of electrical enclosures for electrical connections. They screw directly through threaded openings in tank walls to heat liquids, viscous fluids, forced air, and gases by direct contact. The screw plugs are in sizes 34, 1", 1.25", 2", and 2.5". Wattages range from 100 to 18000.

Ideal for generating steam and heating gases and liquids in pressure vessels and tanks, flanged immersion heaters are hairpin-bent tubular elements welded or brazed into a flange and provided with electrical enclosures. Flanged immersion heaters are available in a wide selection of flange sizes and with a variety of electrical enclosures. Most units are UL-listed and CSA-certified or can have ATEX certification. ASME or PED code construction is also available for high-pressure applications. Flanged Immersion heaters can be made up to mega watt sizes. SCRs are best used to control these large loads.

In-pipe immersion heaters utilize drywell type heaters with open coil element assemblies that can be removed and serviced without draining tanks or systems, eliminating down time. Easily installed the heavy-duty assemblies weld directly into storage tanks to deliver long term and economical performance. Once installed, the flexible heater elements are removable from heater tubes without the need to drain the tank or disconnect fluid lines. LO-DENSITY IS A BIG PLUS. The large heater surface area is designed with a pre-determined low watt density (wattssq. in.) giving low sheath temperatures to avoid coking or damage to the material being heated.
