The dew point control system

The dew point energy-saving programme delivers savings of up to 45%. There are two drying systems, which differ in terms of energy consumption:
On the one hand there is the energy-intensive system which switches in cycles, irrespective of the moisture in the drying container. This does not take into account whether dry or moist air is being used for the drying process. On the other hand there is the energy saving system; its operation depends on the dew point.

The KOCH dry air dryers take the dew point into consideration as they operate. They do not switch to the new desiccant container until the dew point has reached -30°C. The dryer always adjusts to the actual circumstances. For wet plastic material, the cycles are shorter; for dry materials, the cycle is accordingly longer.
The benefit is obvious: A lot of energy is saved in the regeneration and the quality of the end product remains consistent.
