The metal sheath isolates and protects the
resistor wire from the environment. At the
same time it maximizes heat transfer capability
to the work. Fintube® elements can be bent to
put the heat where it works best.
Fins greatly increase surface area and permit
faster heat transfer to the air, resulting in
lower element surface temperatures. High watt
density permits use of fewer elements and
a higher concentration of installed kW for a
Fintube® heaters are ideal for both comfort
and industrial process air applications.
Best suited for the following applications
where space is limited.
- Heat Treating
- Load Banks
- Curing Ovens, Dryers, Ducts, etc.
Type 3 Terminals — Standard. Integral parts of the element are of high strength to resist bending during tightening of the wiring connections. Type 3 terminal is a threaded extension welded to the cold pin. See standard terminal detail in the FT Series Overview.
Work Temperatures — See Allowable Watt Density & Heater Selection Graphs G-151 through G-156 in Technical section of this catalog.
Bending — Customer’s minimum bending radius, see Factory and Customer Bending Table in the FT Series Overview.
Stainless Steel Sheath — Optional. Contact your Local Chromalox Sales office.
Special Features — Sheath material, threaded fittings, length, volts, watts, brackets, etc. Contact your Local Chromalox Sales office for price and availability.
