Extra Large R&D Freeze Dryer – QualiRFD™ 15S
Food Freeze Dryer projects often start in R&D, where you lock down a repeatable lyophilization cycle before scale-up. QualiRFD™ 15S is an R&D Freeze Dryer platform stoppering configuration, built for vial-based drying and small-scale production work.
The model is presented for bioproduct research, in-vitro diagnostic reagents, and similar lab-to-pilot workflows. It also supports drying of bulk materials such as liquids, pastes, and solids when your process allows. Stoppering after drying helps reduce moisture reabsorption and supports long storage.
QualiRFD™ 15S uses an in-situ, dual-chamber layout with a drying chamber and a cold trap to support automated freeze-drying runs. The controller is described as PLC-based with PID temperature regulation for stable shelf control.
Each shelf layer includes independent sample temperature probes to help you track product temperature during development. A nitrogen backfill function is listed for inert-gas handling at the end of a cycle. The control system is described with a large touchscreen and the ability to store many programs with multi-segment temperature steps.
