Backer finned tubular heaters feature mechanically-bonded continuous fin which assures excellent heat transfer and helps prevent fin vibration at high air velocities.  We offer several standard formations and have a variety of mounting bushings available.  Our standard fin is high temperature painted steel with steel sheaths.  Optional stainless steel fin in stainless steel or incoloy sheath for corrosion resistance.  120v, 208v, 480v are available  and maximum sheath temperature range from 750°F (400°C – Steel) and 900°F (480°C – ST.ST./INCOLY).  Backer finned tubular heaters are made in the USA.
