1-2 Equipment Function
Sterling membrane mini dryers are designed to generate heated,
dehumidified air at carefully controlled temperatures for use in
plastic drying systems. Drying systems are sized to meet the
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.
Sterling dehumidifying dryers are used to generate very low dew
point air heated to a controlled temperature for drying plastic
pellets and regrind.
