Strip heaters, or component heaters, provide an easy and efficient way of using surface area for effective heat transfer.

Steel strip heaters are an excellent industrial heating product. Using a temperature controller such as a mechanical thermostat makes them easy to control. Installing a bimetal thermostat on the heated surface is another cost-effective solution for strip heating.

Installing strip heaters

Mounting holes help mount process heaters securely on almost any surface, with the terminal extending from the sheath for easy electrical connections. Many users also request lead wires that extend from one end that make the installation more flexible as the temperature control panel is easily adaptable to this configuration.

Strip heater features

Temperatures reach as high as 500℉ (260℃) and use the high-quality magnesium oxide found in tubular elements that allow effective heat transfer. An inexpensive way of heating surfaces or small areas, strip heaters are an excellent solution to meet any budget.

Strip heaters are composed of a heating element, a protective sleeve or sheath, and mounting hardware. Radiant heater strip heaters can have fins to maximize surface area and heat transfer to the air. Strip heaters can be clamped or bolted onto objects or solid surface contact heating over large areas. That makes them optimal for indoor applications where strip heating can be applied.

  • Options
  • Mounting Space

    Use insulators if a limited mounting space is ½” longer than the strip heater. WATTCO™ strip heater mounting tabs are punched prior to insulator installation.

  • Insulators

    Use additional insulators when voltage to ground is over 300V

  • Brass Bus Bar

    WATTCO™ perforated brass bus bar are solid conductors to connect several strip heaters in series or parallel. For higher current-carrying capacities, all WATTCO™ bus bars can be specially configured to meet your requirements.

  • Terminal Box

    For CPS strip heaters: • Terminal box is supplied with BX cable fitting • Terminal box is mounted in any of the four directions according to your requirements.

  • Surface Clamp

    Use heavy-gauge, nickel-plated steel clamps for mounting WATTCO™ strip heaters to large surfaces (tank walls, platens, dies). Weld, braze or thread threaded 3/8” diameter studs into the work areas.

  • Ceramic Post Terminal Covers

    Use ceramic post terminal covers for: • Heaters with standard 10-32 threaded terminals at both ends • Heaters with offset terminals at one end Also use ceramic post terminal with insulated wiring in order to be electrical shock proof.
