Pre-Vacuum Unit
The Pre-Vacuum Unit is a critical component of the freeze-drying system, responsible for creating the required low-pressure environment in the drying chamber. It ensures efficient sublimation of ice into vapor during the primary and secondary drying phases, enabling superior product quality and process reliability.
