SierraTherm 4500 Series

Conveyor Dryers & Curing Ovens

The SierraTherm 4500 Series Conveyorized Drying Ovens are available as free standing units or they can be attached in-line to a high temperature series furnace for pre-dry before firing. The 4500 series are rated for temperatures to 300° C for applications such as Thick Film Ink drying, Epoxy Curing, and any other low temperature process.

Advantages

  • Super efficient power-saving insulation reduces energy bills.
  • Innovative atmosphere distribution and management eliminates thermal shock.
  • Vigorous extraction of burn-off effluents across entire chamber width improves yields.
  • Integrated burn-off condensate entrapment/collector inhibits process contamination.
  • Stable, unsurpassed temperature uniformity control ensures consistent "firing" results.
  • Air or Nitrogen atmospheres.

Included as standard equipment on the 4500 Series is the powerful and convenient Windows-based MicroTherm PC Control, Profiling, and Monitoring System, first developedand introduced by SierraTherm in 1992.
