LYOVAC ECO Mode

LYOVAC ECO Mode: a solution for tomorrow With a focus on saving both energy and media, GEA's new LYOVAC(R) ECO Mode combines dynamic condenser temperature control and mushroom (chamber/condenser) valve regulation to optimize the lyophilization process. Our new algorithm changes the set point of both the fluid condenser temperature and the position of the mushroom valve during drying. What this means is that there's no longer an actual fixed temperature for the condenser ... but it's optimally matched to the ongoing process and no colder than absolutely necessary. In addition, the mushroom valve opening position can optionally be used as an extra control mechanism ... as well as the nitrogen inflow rate. This allows the freeze dryer to reach the same chamber pressure, but with warmer condenser coils. As such, less nitrogen is needed to control the pressure. The system can also be augmented with a virtual sublimation sensor if required
