OPTI-DRY® PC/PLC Control
Laboratory Freeze Dryer comes complete with PLC controls and a PC for programming and data collection. Our easy-to-use software, Opti-Dry, provides automatic freeze-drying, defrost, and system test. Data can be printed either numerically or graphically. This same control system can be used on industrial dryers, allowing scaling to production. An interactive maintenance screen simplifies component servicing.
OPTI-DRY uses an ethernet platform for hardware connectivity making data transmission extremely fast. It also provides web connectivity for those who want remote access to their systems.
