The flanged immersion heater contains a circular or flat tubular heater that is fixed to a flange wit, four or six studs and terminals for connecting wiring. Flanged heaters are bolted directly to an associated flange fixed to the wall of the tank or to a nozzle. This makes changing easy, as you only need to unbolt the heater and mount a new one, and helps minimize maintenance downtime.
Circulation, or in-line heaters are ideal for processing fluids that require intermediate heating while maintaining a flow rate. They are self-contained units, with the heater wrapped in an insulated tank. These heaters have inlet pipes and outlet pipes allowing the fluid to flow through the tank until it has been heated to the required temperature.
This type of immersion heater is extremely responsive and provides an even distribution of heat. It is also easy to install, maintain, and is compatible with the majority of the current standard industrial piping.
