Immersion Heaters

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 be formed and shaped into various geometries. The heating elements are offered in a number of materials suited to a variety of fluid heating applications. Terminal housings are available for indoor, outdoor and hazardous environments. Many options are available including thermostats, high limit and process thermocouples or RTD sensors.
