Dryers Brochure - Wittmann - #6

The DRYMAXER60 segmented wheel dryer combines both the advantages ofa twin bed desiccant dryer with those ofa desiccant wheel dryer. The DRYMAXER60 offers a constant low dew point, extremely energy efficient operation and the easy exchange ofdesiccant without costly wheel replacement.

The thermal energy ofthe drying process exhaust air is recovered to reduce the total energy required. Thus, the dryer constantly saves energy during the drying process.

The regeneration temperature and revolution speed ofthe wheel are automatically adjusted to achieve the freely selectable constant dew point (dew point sensor optional) and thus, reduces energy consumption.

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

The integrated dew point display with alarm function offers energy savings as the dew point reading can be used to delay switchover ofthe bed until a user defined dew point level is reached.

Highest efficiency is 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).
