VACUUBRAND VARIO chemistry pumping units control the vacuum level with pinpoint precision by adjusting the diaphragm pump’s motor speed continuously.
They enable automatic detection of vapour pressure and variable adjustment of the vacuum level to the process. The fast and precise adaptive control always adjusts the pumping speed to the optimal level, regardless of installation size or gas volume. Process times are shortened by the high evaporation rate.
Through constant evaporation, an optimal solvent recovery rate can be achieved. On the whole, the demand-oriented motor speed control reduces the workload of the vacuum pump significantly. This leads to unrivalled lifetimes for moving parts.
