Ideal For Heating
Liquids, Gases,
Tanks and Pressure
Vessels Requiring
Higher Kilowatts
Watlow flange heaters are easy to install and maintain.
Designed for heating liquids and gases in tanks and pressure
vessels, flange immersion heaters are ideal for applications
requiring higher kilowatt output.
Watlow flange heaters are made with WATROD or
FIREBAR
®
tubular elements brazed or welded to a flange.
Stock flange heaters are equipped with a general purpose
(NEMA 1) terminal enclosure.
Flange heaters, with FIREBAR elements, also answer the
need for liquid immersion applications requiring high kilowatt
output in small tanks.The FIREBAR element's unique flat
surface geometry packs more power in a smaller bundle, with
lower watt density, making it especially well suited for
petroleum-based liquid heating applications.

Benefits
• Provide appropriate heater
size-to-application and fit
• Fits a wide range of industrial
needs
• Compatible with media being
heated
• Provide convenient temperature
sensor insertion and
replacement without draining the
fluid being heated
• Offers easy access to wiring
and ensures safety to user
• Provide proper element
spacing to maximize heater
performance and life
• Facilitates lifting of heavier units
• Ensures element-to-flange
pressure seals do not leak
• Pack more kilowatts in smaller
bundles—in liquid immersion
applications, a conventional
10-inch round tubular element
flange can be replaced with a
6-inch FIREBAR flange
• Maintains MgO density,
dielectric strength, heat transfer
and life
• Meets applicable safety codes
• Designed and built for safety
