Over The Side
Immersion Heaters - All applications must consider the suitability
of the sheath material, the correct watt density, the mounting
method to fit into the tank, available length along the tank
bottom, the riser height, size of the tank opening and appropriate
terminal enclosure.

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
