Flange-Mount Immersion Heaters for Water
Bolt these heaters to a matching flange welded on a container wall. They make direct liquid contact for fast and efficient heating. All accept a temperature switch with a 3/8” dia. probe (sold separately) to regulate heat output. The heating element is Incoloy for excellent corrosion resistance.
Note: Fully immerse the heating element to prevent heater failure.

A replaceable fuse cuts off power if the heating element reaches 190° F to prevent burnout and premature failure. Bolt the flange to the top of containers. Heaters make direct liquid contact for fast and efficient heating. The heating element is 304 stainless steel for good resistance to harsh chemicals.
Heaters without temperature control require a temperature switch or controller (sold separately) to regulate heat output.
Heaters 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 digital keypad.
Optional 329° F fuse (sold separately) cuts off power if the heating element reaches 329° F.
Note: Immerse the heating element in liquid up to at least the minimum coverage level to prevent heater failure.

Low-Profile Enclosure Heaters
Radiate heat inside narrow spaces to keep equipment warm and dry. These slim heaters fit where standard ones don’t. They protect equipment from premature failure caused by cold, condensation, and humidity.
Heaters with a thermostat automatically turn on and off to maintain the set temperature range. Heaters with a nonadjustable thermostat have a set range that you cannot adjust.
