    Compact Screw-Plug Immersion Heating Elements for Oil and Coolant

    Image of Product. Front orientation. Heating Elements. Compact Screw-Plug Immersion Heating Elements for Oil and Coolant.
    Image of Attribute. Front orientation. Contains Annotated. Compact Screw-Plug Immersion Heating Elements for Oil and Coolant.
    Heat oil or coolant inside small containers to reduce the viscosity of the liquid and improve flow. These heating elements fit in compact openings that are 1 NPT or smaller. With a low-watt density, these heating elements operate efficiently and won’t burn out when used with a wide range of oils and coolants. The heating element is made of stainless steel, so it resists corroding when exposed to chemicals.
    Both ends of these heating elements are threaded, so one side fits into your tank and the other can be threaded into a conduit to protect the wiring. For the most evenly distributed heating, choose the largest length of heating element that will fit in your container. To control the settings of the heating element they must be connected to a temperature switch or controller (required but not included).
    Note: Fully submerge the heating element in liquid to prevent heating element failure.

    To heat oil and coolant without creating hot spots and damaging the heating element, these heating elements have a lower watt density than heating elements for water or chemicals. They install into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact.
    Note: Fully immerse the heating element in liquid to prevent heating element failure. These heating elements install through threaded container openings or pipe couplings.
    Incoloy Nickel Heating Element—Incoloy heating elements are more corrosion resistant than steel heating elements.
    Without Temperature Control—Heating elements without temperature control require a temperature switch or controller (sold separately) to regulate heat output.
    Adjustable Thermostat—Heating elements with an adjustable thermostat automatically turn on when the temperature drops below the set temperature and off when it rises above the set temperature. Adjust the set temperature with the dial.
