TEMPCO - SERIES KRD Vitreous Silica Quartz Tube Radiant Heater

Product Description

Tempco KRD radiant quartz heaters are one of the most efficient sources of radiant energy.  They are ideally suited for processes that require wavelengths in the medium 4.0 - 2.4 micron band for efficient operation.  These heaters are capable of generating full heat output in 80 - 100 seconds with a cool-down range of 180 - 225 seconds depending on the mass of the resistance coil and power density level.

They offer excellent life when used in either rapid cycling or continuous radiant heating applications, and operate with a surface watt density range of 35 - 40 watts per square inch. 

Specifications:

  • Voltage: 120V - 480V
  • Wattage: 480W - 3475W
  • Maximum Amperage: 20A
  • Temperature Range: 700 °F (371 °C) - 1715 °F (935 °C)
  • Wavelength Range: Between 2.4 and 4.0 microns (μm).
  • Maximum Watt Density: 40 w/in2
  • Diameters: ø 3/8", ø 1/2", and ø 5/8"
  • Maximum Length: 50" for ø 3/8", 100" for ø 1/2", and 100" for ø 1/2"

Design Features:

  • The heater consists of a helically wound resistance wire coil enclosed in a pure vitreous silica fused quartz tube with a translucent (semi-opaque) surface. 

  • The tubing is terminated at the ends with specially designed ceramic caps securely fastened with high temperature ceramic cement providing support for the field wiring screw terminals used for power connections. 
  • The diffusion effect of the opaque quartz tube surface broadens the emitted wavelength range without creating objectionable glare due to emissions in the visible spectrum. 
  • Optimum design provides a clear red color on the translucent tube surface when operating at full line voltage. The emitted wavelength band is almost completely absorbed by the process and considered best for most industrial radiant applications.
  • See reference page 7-70 for additional features and specifications, mounting clamp specifications, and Type ARK Vitreous Silica Quartz Tube Panel Arrays.
  • See reference page 7-71 for standard sizes, electrical terminations, and ordering information.
  • See reference page 7-71 for standard sizes, electrical terminations, and ordering information.
