compressed air dryer
2-2 General Description
Mini compressed air dryers are designed to generate heated, dehumidified air at carefully
controlled temperatures for use in plastic drying systems. Drying systems are sized to meet
specific requirements stated by the purchaser at the time of purchase.
Moisture removal from hygroscopic (moisture attracting) plastic pellets is an essential step
in the manufacture of high-quality plastic products. This dehumidifying dryer is used to
generate very low dew point air, heated to a controlled temperature for drying plastic
pellets and regrind.
Many variables were considered in the selection of your drying system, including type of
materials, residence time, throughput of the extruder or injection molding machine. Should
your operating environment change, the manufacturer can advise you on necessary
equipment and process time and temperature modifications required for your system.
