The FTS series has been discontinued. Please contact our Temperature Engineering department for a viable replacement.
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.

* The overall length of A will be slightly less than one-half the original sheath length,
depending on bending radius.
** The overall length of A will be approximately 3.8 cm (11/2") longer than one-fourth of the
original sheath length depending on the bending radius R.
Note: the start of any bends should be no closer than 8.7 cm (37/16") for 1.2 cm (0.475") dia.
or 9.2 cm (35/8") for 0.8 cm (0.315") elements, from the end of the sheath to prevent the
heating element/cold pin junction from being located in the bend. |
