Pipe Insert Heaters offer you the advantages of direct
immersion heat, and the ability to service the heater without
draining the tank.The Incoloy sheathed element inside the
pipe is carefully deigned for this application, and transfers
its heat to the inside pipe wall by convection and radiation.
The large surface area of the pipe in contact with your liquid
greatly reduces the watt density (watts/in
2
), making the
pipe insert heaters ideally suited for heating:
• very viscous materials like Bunker C Fuel Oil,
• temperature sensitive materials like glucose, liquid sugar
• bulk storage of corrosive material
Pipe inside the tank supplied by the tank manufacturer
Low Liquid Protection
To prevent Low Liquid failure, one of multiple heaters
should have a built-in thermocouple, series PFHK, and this
heater must be mounted slightly higher than other heaters
in the tank. When a Low Liquid event happens the air
temperature inside the pipe rises dramatically and the
thermocouple sends the temperature signal to your
remote mounted high limit control for shutdown.
