Watlow manufactures high-temperature tubular heaters to bridge the
gap between standard tubular heaters and Watlow MULTICELL™ heaters. This
high temperature heater is well suited for process air heating
applications in excess of 1300˚F (704˚C), resulting in a maximum sheath
temperature of 1800˚F (983˚C). Controlled lab testing between the new
design and current tubular designs shows an increase in life of
approximately 50 percent.
The high-temperature heaters consist of an engineered tubing with an
outer sheath of Inconel® 600 and a special internal construction. The
outer sheath offers high temperature capabilities, reduced oxidation as
well as corrosion resistance.
The tubular heater offering is available in 0.430 and 0.375 inch
diameters that are configurable either as formed tubulars or process
heaters. The tubular heaters can also be welded to flanges and plates
for mounting purposes. Maximum sheath length available is 275 inches for
the 0.430 inch and 0.375 inch diameters. The factory should be
contacted for longer sheath lengths.
