Benefits of Batch Ovens, Smokehouses, Chillers & Industrial Dehydrators

Marlen’s innovative batch thermal processing technology delivers the uniformity and efficiency no other batch oven can match.

  • Uniform Processing Conditions.
    Permanent air balance of supply and return air results in full control of the all-important “breakpoint” – the physical point at which the high velocity air mass collides with the low velocity air mass. This ensures that the breakpoint stays where it’s supposed to be which is essential for repeatable process and quality, uniform product.
  • Breakpoint on Demand. Programmable encoder enables control (pause, stop, or accelerate) over rotating dampers for precise control of breakpoint.
  • Ease of Operation and Maintenance. Efficient air handling system eliminates need for balancing or adjustment of any kind while control is made easy with Powis Corporation technology, the most responsive and intelligent computer control system in the industry. Generous service access area enables change-out of wet bulb wicks while the oven is loaded with product.
  • Less Energy Consumption. Unique design requires 20-25% less horsepower to deliver the same air flow as other single fan ovens and up to 50% less horsepower than multi-fan ovens.
