In scenarios with changing process parameters, we recommend vacuum pumps that can be controlled on a demand-driven basis and that either guarantee a consistent pumping speed or constantly maintain the required vacuum level.
For processes with constant vacuum demand, it is recommended to leave the vacuum pump running at constant speed.
For processes with changing vacuum demand over time, the pressure control mode is the ideal choice. In this case, the vacuum pump adjusts the rotational speed according to the required vacuum level. Once this vacuum level has been achieved, the vacuum pump continues to run at minimum speed, enabling it to respond to a sudden need for increased vacuum demand and leading to further energy savings.
