Over the Side Heaters

 

immersion heaters Used in tanks where through-the-wall heaters cannot be installed, portability is required, or where heaters must be removed for cleaning without emptying the tank. Suitable for freeze protection, for heating viscous materials to improve flow, or most open tank applications with proper sheath and watt density selection.

Depending upon sheath material and watt density considerations, OT Immersion Heaters can be used to heat many various solutions.

Easily installed or removed for cleaning, inspection
or moved to improve heat distribution
Narrow profile to allow maximum work space in tank
Moisture/explosion resistant terminal enclosure
Optional cord and plug
Specify passivation or other external finishing if required
Items equivilant to Chromalox PTH and PTHT are
also available.
