Commonly referred to as "Incoloy" elements or
"Rod" elements, tubular sheathed elements have
a wide range of applications in both the domestic (oven
grill and bake elements, stove plates etc.) and industrial
(bakery, catering, airconditioning, industrial water boilers
etc.) sectors. Swift concentrates exclusively
on the industrial sector of the heating market and is
a leading supplier of tubular elements to SA industry.
|
TSE's have the distinct advantage of maleability allowing
infinite numbers of different designs from a single length
as well as over 60 locally stocked standard 220V tubes
of varying wattages, lengths and sheath materials to ensure
most local requirements can be accommodated within 5 days.
Special requirements are processed in +-20 working days.
|
|
TSE usage in the industrial sector can be categorised
into Air and Immersion Heating. Depending on the application
this will determine the intensity of heat in a square
area (Watt Density) and the Sheath materials used in the
manufacturing process. |
 |
Uses Stainless Steel 321 as the corrosive attributes of
normal air are very low. (Stable up to 650 - 700 °C).
Depending on air flow/rotation one can use elements from
as low as 3.1 Watts per Sq. Centimetre (Black Heat) up
to 5.5 Watts per Sq Centimetre (Red Heat) to suit time
periods and applications.
Fittings can be supplied to spec with the most common
air application fittings being
o 12mm x 25mm Mild Steel Crimp-on Bush
o 12mm x 25mm Brass Bush
o Mounting plate to suit machine/plate

Generally operate with high watt densities (5.5 - 15 Watts
per Sq centimetre) in order to give quick heat up times.
This is possible as the liquid dissipates heat quickly
and does not allow sheath temperature to rise above oxidisation
point (650 - 750 °C depending on Sheath material)
supplies all high Watt Density
tubes in a Incoloy 840 sheath as many immersion applications
have corrosive attributes and all Incoloy materials have
a significantly higher Nickel/Chrome content than Stainless
Steel. Incoloy was specially designed for the TSE market
as the higher Nickel/Chrome content gives a higher resistance
to oxidation under temperature (max 700 - 750 °C)
as well as superior resistance to corrosive substances.
|
Immersion elements can be placed into numerous housings
to suit your application.
o Individual Bushes in any material
o 1" 1.25" 1.5" 2" 2.25" and
2.5" bosses in Brass, Mild or Stainless Steel.
o Any size or material Flange
