Dryers Brochure - Wittmann - #8

The DRYMAX battery dryer series are equipped with two desiccant beds and therefore provide continuous process airand constant dry air quality for the perfect drying of plastic resin.

The switchovervalves provide optimized control ofdrying and regeneration cycles in both desiccant beds.

Reduces 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 production stoppages ofthe processing machine.

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

Time-optimized control ofthe regeneration and cooling ofthe desiccant beds.

For separate process and regeneration blowers in order to guarantee constant air flow even during fluctuating pressure conditions.
