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.

Application

For evaporation, distillation, drying and all other processes that require precise vacuum control, stagelessly adjustable pumping speed or demand-oriented vacuum supply.

The Vacuum Controller CVC 3000 quickly determines the optimal vacuum level and adjusts it fully automatic to the process demands. It has an integrated capacitive pressure gauge made of alumina ceramic. Another feature of the CVC 3000 are the ten freely configurable programs, which can be edited and stored easily.

Even with gas ballast the chemistry pumping units reach excellent ultimate vacuum levels. This enables the easy evaporation of even high-boiling solvents.
