TUBULAR & FLANGE HEATERS
Tubular & Flange Heaters
The building block of every electric heater — custom-formed tubular elements and flanged immersion banks built to your geometry.
OVERVIEW
What it is
A tubular element is a resistance coil inside a metal sheath, insulated with compacted magnesium oxide and formed into virtually any shape. Alone or assembled into flanged immersion banks, tubular heaters heat liquids, gases, molds and metal parts directly.
We manufacture to drawing: diameter, length, bend radii, sheath material (copper, SS304, SS321, Incoloy 800), watt density and terminal style are all matched to the medium and service life you need — the same elements we build our own heaters from.

APPLICATIONS
Where it works
02
Molds & platens
Cartridge-style and formed elements for hot plates, molds and dies.
03
OEM built-in heating
Custom elements engineered into your machine — one-off to series production.
04
Tanks, moulds and vessels
Direct electric heat for tanks, moulds and vessels where the mounting geometry is as important as the heat load.
SELECTION INPUT
What we need from you
Five inputs are usually enough for a preliminary selection and power estimate. You do not need a complete data sheet to start the conversation.Medium and required power / watt density
Geometry: length, bends, fixing method
Sheath material against corrosion and temperature
Termination and terminal box environment
Lifetime expectation vs. surface load
FAQ
Common questions
How do I choose the sheath material?
Water and mild liquids: SS304 is standard. Oils and mild acids: SS321 / SS316. High temperature or corrosive media: Incoloy 800. Tell us the medium and we confirm.
Can you reproduce an existing element?
Send the drawing or a sample with dimensions, power and terminal photos — we quote a like-for-like replacement, often with improved watt density margins.
What limits element lifetime?
Surface load (watt density) against the medium's heat-removal ability. Overloaded elements run hot internally and fail early — correct sizing doubles or triples life.
What information is needed for a custom element?
Please provide the medium, temperature, power, heated length, diameter, material, mounting method and electrical connection requirements.
