Product Description

Description
Electric Finned Tubular Air Heater 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.

finned tubular heaters provide rapid heat transfer for natural convection or forced air space heating in industrial process air heating systems. Finned tubular heaters start out as a standard tubular heater with the fins being attached
on a custom built finning machine.
