Building on the proven success of the Wizard Control System, Wizard 2.0 again exceeds the control power and user-friendliness of any other embedded microprocessor control system. With complete recipe management and full alarming, it provides full process automation for the VirTis freeze dryer line, including AdVantage, Genesis, and Ultra Lyophilizers.

Wizard 2.0 handles single or multiple refrigeration compressor applications and boasts a long schedule of options. Its powerful microprocessor is fast enough to accommodate multiple temperature transducers, while providing instantaneous alarming for out-of-designed-cycle conditions.

Select any of 16 recipes and a new, larger center-stage LCD display precisely plots the profile of the directed shelf temperature, while providing a cycle progress bar graph. The display continually scans all configured transducers. if an alarm occurs, the display indicates the out-of-tolerance condition.

To minimize warming during the condenser and vacuum phases, the Wizard 2.0 control can be configured in a special freeze assist mode. Once configured, the control can keep the product at the obtained freeze temperature until primary drying conditions are achieved.

Two Methods of Control The Wizard 2.0 unique configuration and validatable software allows the freeze-drying cycle to be either shelf-driven or product-driven, depending on which best suits the application.

In the product-driven mode, Wizard 2.0 uses the product temperature average to determine if freeze conditions have been achieved and when to advance from primary to secondary drying. When shelf-driven, the Wizard 2.0 directs drying through a shelf temperature profile. Product temperature probes can be utilized to monitor cycle conditions.
