Precision dryers aimed at medical, other apps

A new range of plastics dryers is targeting processors’ increasing desire for auxiliary equipment able to help them process low-throughput, high-end materials. Called Precision Micro dryers and made and marketed by Dri-Air Industries (East Windsor, CT), these dessicant dryers are able to process from two pellets to 20 lb/hr, with drying temperatures from 70–400°F. No cooling water or after coolers are needed. A continuous stream of –49°F dew point air is generated regardless of the ambient conditions in a facility.

A range of configurations are available for these dryers, including compact all-in-one drying systems that can fit on small extruders or molding machines, to separate systems with 2-oz hoppers and standalone dryer packages. They can also be configured to use nitrogen when oxygen-free drying is required. Standard on these is the manufacturer’s UDC controller, with its ADC controller as an option. The ADC control includes a –49°F dew point monitor, 7-day timer, and temperature set-back to prevent over drying. Both the UDC and ADC controller can be calibrated for ISO 9000 and 9002. —mpweditorial@cancom.com
