Chromalox ARTM0-1XX 089CP Immersion Heater

Chromalox ARTM0-1XX 089CP Immersion Heater delivers direct, compact heat for liquids in small tanks at 120 V and 535 W. This screw-plug immersion heater threads through a tank wall so the heated element is in direct contact with the liquid, making it well suited for heating water, mildly corrosive solutions, and light oils in small vessels. It is part of Chromalox’s ARTM/ARTMO screw-plug family, featuring a tubular heating element welded or brazed to a threaded hex plug for uniform heat distribution and longer element life. Many ARTM configurations include a welded thermowell that enables thermostat sensing element replacement without draining the tank. Standard NPT plug sizes in this family range from 1/2" to 2-1/2" (with common increments around 1/2" to 2"). In models within the ARTM/ARTMO line, thermostat options exist with ranges such as 60–187 °F (T4), 60–240 °F (T5), or 0–127 °F (T8), depending on the version. The CP suffix on this variant typically denotes copper sheath construction, aligning with copper-sheathed ARTM models.
