Travaini Hydrotwin liquid ring vacuum skid is the new series of compact high vacuum packages that guarantee a working vacuum level up to 5 mbar (absolute) and capacities up to 2500 m3/h. The package has been developed in close co-operation with Bora Blowers who specialises in manufacturing pressure and vacuum boosters. A sophisticated electronic control for booster operations has been developed to prevent risks of booster seizure in the event that operating conditions exceed allowable working parameters.
