For the drying of thermoplastic granules and regrind, independent of climate or ambient air conditions, before processing to remove all remaining moisture from the granules both inside and out.
Rugged, modular construction
Colortronic dry air dryers operate on the principle of absorption. Under this principle, the air is not heated, rather the moisture is absorbed and removed from it inside the drying hopper. Through this technology plastic granules can be dried to extremely low residual moisture levels (i.e. 0.002% with PET). Colortronic Dry-Flex S dry air dryers have 2 drying cells which continuously maintain a dew-point level of up to -60 °C. Because our air flow is constant, we maintain zero temperature change during the drying process.
Colortronic dry air dryers are virtually maintenance free. Only the air filters require routine cleaning or change out.
