VARIO® Chemistry Pumping Units offer all the advantages of modern control technology and provide excellent possibilities for solvent recovery. They attain an ultimate vacuum down to 0.6mbar. They are exceptionally quiet in operation and entirely oil-free. Inside the pump, vapours and gases only come into contact with fluoroplastics of optimum chemical resistance. VARIO® Chemistry Pumping Units provide vacuum control by adaptation of motor speed. This has clear advantages compared to even the best of two-point control systems. The vacuum is continuously adjusted to actual process requirements, irrespective of apparatus size and vapour volume. Process times are typically shortened by 30%. Solvent recovery next to 100% is supported through continuous evaporation. All VARIO® Chemistry Pumping Units include a chemistry diaphragm vacuum pump and an integrated vacuum controller with display and vacuum sensor.
