Compressed Air Dryer Chapter 2: Functional Description 9 of 31Chapter 2: Functional Description2-1 Models Covered in This ManualThis manual provides instructions for installing and operating your 5, 10 or 15 cfmcompressed air dryer.2-2 General DescriptionMini compressed air dryers are designed to generate heated, dehumidified air at carefullycontrolled temperatures for use in plastic drying systems. Drying systems are sized to meetspecific requirements stated by the purchaser at the time of purchase.Moisture removal from hygroscopic (moisture attracting) plastic pellets is an essential step inthe manufacture of high-quality plastic products. This dehumidifying dryer is used togenerate very low dew point air, heated to a controlled temperature for drying plastic pelletsand regrind.Many variables were considered in the selection of your drying system, including type ofmaterials, residence time, throughput of the extruder or injection molding machine. Shouldyour operating environment change, the manufacturer can advise you on necessary equipmentand process time and temperature modifications required for your system.2-3 Typical Features and Components· Electrical solenoid valve· Compressed air filter, regulator, and gauge· Drying temperature range of 120ºF to 400ºF· Display of process temperature set point and actual settings· Process thermocouple located in the process air stream just before the hopper inlet· Nema 1 control enclosure:a.
