Up to 13 kW per sq.ft. (Tubular)

Up to 15 kW per sq.ft. (Finned Tubular)

Heating elements not in direct contact with air

Element of U or W shape:

  • Tubular Elements:
    -Incoloy 840 (Nickel alloy)
    -Stainless Steel 316L (optional)
  • Finned Tubular Elements:
    -Steel tubes with Steel fins
    -Stainless Steel 316L tubes with Stainless Steel 304 fins (optional)

Integrated HEC controller


The Tubular and Finned Tubular heater type offers
an excellent mechanical resistance, suited for
demanding environments. These elements are less
sensitive to humid and dusty environments but offer
a slower response time.

Tubular vs Finned Tubular

Tubular Elements:
- Incoloy 840 (Nickel alloy)
- Stainless Steel (optional) tube with a diameter of 7/16"
(11mm) with heating coil in magnesium oxide powder

Finned Tubular Elements:
- Steel or stainless steel (optional) tubes, with fins installed on the tube to allow a higher heat dissipation capacity.
