Dryers Brochure - Wittmann - #5

The DRYMAXED80 Series dry air dryers are equipped with two independent process blowers and desiccant beds, which upon demand can be operated in parallel to provide shortterm higher dry air performance.

In the single hopperversion two independent process blowers already permitvariable airdistribution (SmartFlow) based on the actual material flow.

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

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

Fortime optimized control ofthe regeneration and cooling ofthe desiccant beds.

Integrated dew point display with alarm function. For energy savings the dew point reading can be used to delay the bed switch-over until a user defined dew point level is reached.

Highest efficiency directly integrated into the filter housing and retrofittable without tools.

Dust separation efficiency of up to 99.9% for high process safety of materials with optical quality (on DRYMAXD60 and 100).
