Tubular Heaters

Tubular heaters are used across a wide range of industries, in many different process heating applications, as they can be configured into almost any size or shape. Tubular heaters work on any of th ethree principles of heating- conduction, convection, or radiation. A tubular heater produces heat within a confined area. The result is heat directly radiated into the material, conducted via a suitable liquid or convected via a force air system.

Features
1.
UL & CSA Recognition.
2.
Incoloy 840 sheath standard on all items-allows for the widest coverage of applications and temperatures, plus gives a margin of safety should there by any unknown corrosives or contaminants in the application.
3.
High purity MgO powder compacted to provide maximum heat conductivity and optimum dielectric strength.
4.
Type ‘A’ 80/20 resistance wire sized to provide lowest wire watt density for maximum life.
5.
Fusion welded junction between pinlresistance wire to provide a 360° circumferential joint, giving superior strength and life
6.
Choice of end seals for a variety of applications. See item 2, adjacent column.
7.
Integral cold pins centered in compacted MgO of nickel plated steel to provide optimum in current carrying capacity.
