Dryers Brochure - Wittmann - #4

The DRYMAX Series dry air dryers are equipped with two desiccant beds to supply con­tinuous dry process airand constant quality for the perfect drying of plastic resin.

Operation withoutcompressed air lines and optimized control ofdrying and re­generation cycles in both desiccant beds.

Reduced energy costs through fastest dehumidification ofthe desiccant beds during the regeneration phase.

Avoids over-drying and thermal degradation ofthe plastic resin through short term lowering ofthe drying temperature during the production stoppages ofthe processing machine.

Dust separation efficiency of up to 99.9% for high process safety. _ SmartRegEnergySavingFunction

For the time optimized control of regeneration and cooling ofthe desiccant beds (on DRYMAXD60 and 100).

Automatic air distribution to adjust to different materials and fluctuating material demands (available on units with 2 drying hoppers).
