Vacuum distillations with high-boiling solvents in most cases need a specific vacuum pressure while the temperature can be kept variable. Vacuubrand's attemp to increase evaporation rates keeps the vacuum nearly constant at the vacuum set point using a solenoid-operated vacuum valve. The company says that thereby even solvent mixtures can be separated sufficiently in reduced process time. The vacuum control packages can be used for small flange connection KF DN 16 or KF DN 25 with single- and double-stage rotary vane pumps. Pumping speeds can vary according to the customer's individual requirements. The packages include all required components (except the pump itself): the vacuum controller CVC3000, a vacuum sensor and the solenoid valve.
