U Shape Stainless Steel Finned Tubular Air Heaters
Product Description
Finned tubular air heating elements are constructed like basic
tubular elements with the addition of continuous spiral fins, 4-5
per inch permanently furnace brazed to the sheath. Fins greatly
increase surface area and permit faster hear transfer to air,
resulting in lower surface element temperatures.
Heater Element for Air is the most versatile and the best suited
solutions to a large number of applications. In applications where
tubular heaters are exposed to forced convection, placing fins
around tubular heaters increases their surface area and thus
improves their heat transferring capacity. Heater Element for Air,
compared to regular tubular heaters ,run at lower surface
temperatures for the same watt densities when placed in identical
air streams. These heating elements have a strong outer sheath to
help protect the heater from physical stress and uses high quality
alloys to allow efficient heat transfer from resistance coil to
your heating medium.
Specification
Finned Tubular Air Heaters Construction
1. Nickel-chromium resistance wire is uniformly stretched and
imbedded into magnesium-oxide powder.
2. Resistance wire is accurately centered within a copper, steel or
alloy sheath.
3. Terminal pins are attached to the resistance coil at each end to
create an unheated zone near the terminals.
