 Over The Side Immersion Heaters
Over The Side Immersion Heaters come in a wide variety of configurations, styles, and shapes. Our goal is create a simple yet effective design to solve any fluid-heating environment you have. By selecting the best sheath material, choosing the optimum fitting method and manufacturing the elements to any desired watt density you can expect the optimum engineered heating solution for your requirements.
Fast delivery gets you this perfect heater almost immediately.
Over The Side Immersion Heaters
- Used when an immersion heater cannot be installed into a tank fitting or
- When heater removal without draining the tank is vital
- These heaters are lowered into the liquid from the top
- Can have very long vertical risers for power connections to be made at the
top of the tank, heaters with a 45 foot vertical risers have been installed
- There is no heat generated in the vertical riser
- General purpose terminal enclosure (NEMA 1), weather resistant terminal enclosure (NEMA 4), and hazardous location terminal enclosure (NEMA 7), available
- Thermocouples, thermostats, and high limit controls can be built-in
