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 developed
 and introduced by SierraTherm in 1992.
