Mann and Hummel Filter Private Ltd manufacture Durable Booster. Mann and Hummel Filter Private Ltd is DIN ISO 9001 certified. This Durable Booster is used in the plastics-processing industry. A series of technical plastics [PET, PEK or PEEK, for instance] require the least-possible residual moisture for subsequent processing. Of equal significance is the guarantee of a constantly-high inlet temperature of the granules into the processing machine. However, since the oxidation which begins following a longer retention time leads to undesired changes in properties, not all plastic granules can be maintained at the drying temperature beyond the drying time. The durable Booster makes it possible to bring the material to the desired inlet temperature quickly and without risk of damage before the material is introduced into the processing machine.
