  • Industrial Electric Skid Heating

    Industrial Electric Skid Heating

    Combine this with the extreme energy efficiency of electric heaters to maximize the cost-effectiveness of a skid system.

    Applicable Industry or Industries: Oil & Gas, Mining, Chemical Processing. Benefit of Using this Skid: Heater/pump skids are able to maintain a constant temperature throughout the storage tank, preventing freezing, fallout, or stratification.

  • Industrial Immersion Heater

    Industrial Immersion Heater

    An immersion heater heats water directly inside it. Here, there is a heating element immersed in the water, and a strong electric current is passed through it which causes it to heat the water in contact with it.

    An immersion heater is an electric water heater that sits inside a hot-water cylinder. It acts a bit like a kettle, using an electric resistance heater (which looks like a metal loop or coil) to heat the surrounding water.

    WNH’s immersion heaters are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases. By generating all the heat within the liquid or process, these heaters are virtually 100 percent energy efficient. These versatile heaters can also be formed and shaped into various geometries for radiant heating and contact surface heating applications.

  • Screw plug immersion heater

    Screw plug immersion 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.

  • Industrial screw plug immersion heater

    Industrial screw plug immersion heater

    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.

  • Industrial screw plug heater

    Industrial screw plug heater

    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.

  • Screw plug industrial heater

    Screw plug industrial heater

    Screw Plug industrial heaters from WNH are used for heating gases and liquids in tanks or vessels. These submersible heating elements have been designed so that heat transfer will occur at a rapid rate, enabling quick liquid heat up times. Typically they are implemented in the food and beverage industry, laboratory clinics, applications involving hydraulic oils and lubricants as well as more sophisticated uses such as heating up flammable liquids or gases which require explosion proof housing.

  • 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.

  • 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.
