1-1 Models Covered
This manual provides instructions for installing and operating
Sterling SMD30 and SMD60 membrane dryers. The number
designation represents air flow capacity. SMD30 models have a 30
cfm air flow capacity, and SMD60 models have a 60 cfm capacity.
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.
