Screw-Plug Immersion Heating Elements for Oil and Coolant
 |  |
Without Temperature Control —Incoloy Heating Element | With Adjustable Thermostat—Incoloy Heating Element |
 |
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.
