"Plug and play" electronics used on this new series of compact vacuum pump packages guarantees a vacuum level up to 5 mbar (absolute), and capacities up to 2,000 m3/h. This new series allows Pompetravaini to extend the range of vacuum from 33 mbar (absolute) to 5 mbar (absolute.)

The Hydrotwin system from Pompetravaini is a solution for the high vacuum world, not achieved before by liquid ring vacuum pumps. This package was developed in close co-operation with Bora Blowers. Sophisticated electronics couple the liquid ring vacuum pump and the booster to guarantee maximum performance in absolute safety. These electronics control booster operations which avoid the risk of seizure if conditions exceed allowable parameters.

The electronics in the DVD2 control are variable and optimized based on the needed working parameters. With "Hydrotwin" packages, it is possible to:

• decrease to aminimumthe absorbed power. The saving is considerable and can be in the range of 30 - 40%;

• set and maintain the desired vacuum level. This improving the quality and minimize scrap in those processes where maintaining the vacuum level stability is very important for the final result;

• give total protection from seizure due to overheating caused by operating outside the allowed limits.

Standard temperature sensors located in the discharge casing zone cannot show, in real time, any elevated temperature of the roots lobes, that firstly are subject to thermal expansion. Control of temperature is performed with a check on compression rates. Electronic control DVD2 works on the cause, and not on the effect.

Whatever your vacuum application – including pharmaceutical, chemical, plastics, food and pasta production, leather treatment, centralized vacuum systems, etc. – consider Pompetravaini and our commitment to always stay ahead.
