At K-2007, Wittmann unveiled a new dryer that combines the advantages of the twin bed desiccant dryer with those of the wheel dryer, thereby offering an alternative to a twin bed desiccant dryer.

The Drymax ER60 ROTO offers a constant dew point along with energy efficiency and the ability to change inexpensive desiccant without having to replace the entire wheel unit.

According to Wittmann, the regeneration heater in the Drymax heats the desiccant to 240 degrees C, the residual heat of the exhaust air is used in a heat exchanger to pre-heat the incoming air. A second segment cools the desiccant and a third segment is responsible for drying the process air. The entire cooling energy from the cooling process is fed back to the drying process, thereby resulting in an energy optimized and effective drying process.

The drying wheel uses a standard Type A Zeolite can be exchanged by the customer in their plant like a typical desiccant cartridge.

Additionally, according to Wittmann, the Drymax is not limited to only one type of desiccant, allowing for different fillings to be used.
