HIGH-TEMPERATURE TUBULAR HEATERS

IDEAL FOR PROCESS AIR HEATING APPLICATIONS REQUIRING HIGH TEMPERATURES

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 Alloy 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.

  • Alloy 600 sheath material and a special internal construction maximizes performance and corrosion protection in tough applications
  • Dual-ended termination Installs into flanges and screw plugs similarly to standard product configurations
  • Bendable in standard formations makes the heater easy to apply in a wide variety of applications
