Volatile Trap
For materials that give off plasticizer residue when dried, an optional Volatile Trap is recommended to demist the volatiles from the hopper’s return air and collect them prior to the air entering the desiccant. Volatile traps extend desiccant life and reduce maintenance and include a convenient drain spigot.
Precooler
For drying temperatures below 150°F {65 150°C}, an optional Precooler is required to remove the internal heat of the dryer for low temperature drying. Precooler water connections match those of the standard aftercooler as listed in the specifications section.
Process filter check
To conveniently monitor air flow critical for drying, the Process Filter Check option provides an alarm when the resin drying air filter is blinded, jeopardiz- ing effective drying. Process Filter Check provides essential guidance to maintenance intervals.
Communications
When connected to a network the controller on the network may read actual temperatures, change setpoints, read dryer status, and process and display this information at a central location. Ethernet communications are available.
Drying Monitor
Save time and money from the aggravation of improperly dried material. The Drying Monitor automatically monitors the heat profile inside your drying hopper with a 6-zone temperature probe, to protect resin from over or under-drying. A control alarm and a light tower alert if proper drying is in jeopardy. Advanced notice provides time to correct issues instead of wasted drying and product defects from common issues
