Diameter 8mm
Wattage 750 to 2500watts
U Type Finned tubular electric duct heaters
Tubular finned heater element is 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 heat transfer to air, resulting in lower surface element temperatures.
