Circulation heaters operate as an electric heat exchanger by directly heating the process media in an in-line configuration. Units operate at nearly 100% efficiency and offer a compact heating solution. A wide selection of materials is available such as copper, carbon steel, stainless steel, or INCOLOY®. Moisture- and explosion-proof terminal enclosures along with ASME, PED, KOSHA, and SELO are also options. Click here to visit catalog
Immersion heaters can be installed directly in process media such as water, oil, solvents, viscous solutions, and gas streams. Units operate at nearly 100% efficiency and offer a compact heating solution. Common heater installation methods are flanged, threaded, or over-the-side designs, with a wide selection of materials such as copper, carbon steel, stainless steel, or INCOLOY®. Moisture- and explosion-proof terminal enclosures along with IEC, ATEX, and CSA are also options. Click here to visit catalog
These electric heating systems feature unique, replaceable-element designs whereby heating elements can easily be replaced without draining the tank. They require very little upkeep and are practically maintenance-free. When combined with temperature controls, power controls, and safety monitoring they provide complete tank heating systems.

Units are offered with multiple third-party certifications and may be wall- or ceiling-mounted. Click here to visit catalog
Comfort heat sources for hazardous environments. Designed for rugged, corrosive, hard-use areas and use in the presence of potentially flammable or explosive gases, vapors, and liquids. Cabinets are constructed of heavy-gauge steel, polyester powder-coated for maximum corrosion resistance. Click here to visit catalog
Tubular elements provide exceptional heat transfer by conduction, convection, or radiant to liquids, air, gases, and surfaces. Round, triangular, or flat press configurations. Formed bends can be made to unique requirements. Fintube® elements are designed for optimum heat transfer due to increased surface area. Superior to open-coil elements, heating coil is completely encased in a metal sheath, minimizing shock hazard and hot spots. Bending configurations provide higher concentrations of installed kilowatts for given area. Click here to visit catalog
Highly compacted heating elements for high-efficiency heat transfer and the dielectric and physical strength necessary for long life and outstanding performance. Diameters range from 0.25 to 1.25 in. (3.175 to 31.75 mm), watt densities from 25 to 262 W/in.² (4 to 40 W/cm²), and sheath temperatures to 1,600°F (870°C). Optional end seals resist contaminants and moisture. Click here to visit catalog
Rugged, easy-to-install strip heaters transfer heat by conduction or convection to liquids, air, gases, and surfaces. Widths range from 0.5 to 2.5 in. (12.75 to 63.5 mm), lengths to 72 in. (1.8 m). Finstrip® heaters are designed for optimum heat transfer due to increased surface area. Superior to open-coil elements, heating coil is completely encased in a metal sheath, minimizing shock hazard and hot spots. Click here to visit catalog
