The HAD series of PLASTIC SYSTEMS hot air dryers are specifically designed for the drying of non-hygroscopic thermoplastic granular materials.

Non-hygroscopic materials are polymers which do not adsorb moisture within the granules, but hold the moisture on the granule surface, trapping a relatively small amount of humidity.

The processing of plastic materials with the presence of water moisture, however, may seriously affect the process and therefore the quality of the final product.

A HAD unit has a blower that sucks up ambient air and blows it into a process heating chamber to heat it up to a set working temperature.
