Circulation Heaters
A circulation heater is designed to heat liquids or gases as
they pass though the unit. Similar to a heat exchanger,
except this unit generates its’ own heat. An electric fired
circulation heater covers a broad range of heating
applications. A screw plug heater is installed into a pipe
body and multiple units can be series connected to give
you any kilowatt size.
