  • Screw plug immersive heater for industry

    Screw plug immersive heater for industry

    Screw Plug heaters from WNH consist of hairpin tubular elements that are brazed or welded into a machined pipe thread fitting, (normally an NPT fitting for North American standards) which are then screwed directly through a threaded coupling in the tank wall or vessel, or installed in pipe. Screw plug heaters are an easy way to heat up solutions in smaller containers that also require controls. Mechanical thermostats or Digital control panels can be used with these immersion heaters to help reach target temperatures with great accuracy meeting your project objectives. Additional thermowells can be installed for high limit temperature probes to help protect your liquid and processes.

    Screw Plug Immersion Heaters consist of tubular elements welded or brazed into a threaded screw plug which can then be inserted into a threaded opening in a tank wall or through a mating full or half coupling.

  • Customized screw plug immersion heater

    Customized screw plug immersion heater

    Screw plug immersion heaters are ideal for direct immersion heating of liquids, including all types of oils and heat transfer solutions.Heating elements are hairpin bent and either welded or brazed into the screw plug, depending on element sheath and plug material compatibility. General purpose terminal enclosures are standard with optional moisture resistant, explosion resistant and explosion/moisture resistant enclosures available to meet specific application needs. Optional thermostats provide convenient process temperature regulation to the screw plug immersion heater.

  • Explosion proof screw plug heater

    Explosion proof screw plug heater

    Screwplug heaters are typically used in closed vessels and small containers. They have hairpin elements that are threaded directly into the side of the vessel. This direct heating method is the most efficient heating possible with a high degree of accuracy, and the custom fitting ensures a safe, perfect connection.

  • Screw plug immersion heater from China

    Screw plug immersion heater from China

    A screw plug heater is a subcategory of immersion heaters, which typically requires small space to operate. The principle of screw plug heaters is similar to the flanged immersion heaters. The heater is immersed into the wall of the equipment, such as vessels, water tanks or chemical containers.

  • Flange type immersion heater

    Flange type immersion heater

    An immersion heater is an electric water heater that is found inside a hot water cylinder. It works a little bit like a kettle, in that it uses an electric resistance heater (that looks like a big metal loop) to heat the water around it. Immersion heaters are connected to the electric mains via a cable.

  • flange type immersion heater

    flange type immersion heater

    If the vessel is too large for a screwplug heater, a flanged heater is your best option. They provide efficient heating in larger containers. Positioned towards the bottom of the tanks and using custom element designs, flange heaters ensure even heat distribution.

  • Industrial flange heater

    Industrial flange heater

    These heaters have elements extending from the flange, directly submerged in the target medium. A wide range of element materials and coatings are available, so they can withstand almost any environment solution.
