Electric Circulation heaters are used in direct heating applications of fluids either water, oil, F.O etc. The processed fluid is being circulated directly through the heater. The reason you would choose a circulation heater over an immersion heater directly installed in the tank, is either due to space limitations or due to watt density limitations requiring high fluid velocity over the elements to increase heat transfer.

Furthermore, if the circulation heater is piped and valve properly, the heater may be serviced without draining the tank. Circulation Heaters can be manufactured in all dimensions and electric requirements upon request.
