Chapter 2: General Information

2-1 Models Covered

This manual provides instructions for installing and operating 90, 100, 150, and 225 CFM cabinet-style dehumidifying dryers.

2-2 Equipment Function

Our dehumidifying dryers are designed to generate heated, dehumidified air at carefully controlled temperatures for use in closed-loop plastic drying systems. Moisture removal from hygroscopic (moisture attracting) plastic pellets is an essential step in the manufacture of high- quality plastic products. Our dehumidifying dryers are used to generate very low dew point air heated to a controlled temperature for drying plastic pellets and regrind.
