LEYBOLD - Dry Fore Vacuum Systems

DRYVAC systems

For the use of the two to three-stage dry compressing "DS" and "RUTA" pump systems, we combine the DRYVAC backing pumps with RUVAC WA(U), WS(U), WH(U) and RA. A single flow layout can achieve pumping speeds of 250 to 16,000 m³/h. Higher pumping speeds can be achieved by arranging pumps in parallel. The achievable working pressures are defined by the number of pump stages or parallel pump systems.

DRYVAC PowerBoost

Like world-class sprinters, vacuum pumps often need to deliver powerful bursts of energy on demand. For applications like load lock for inline coaters, those peaks are traditionally covered by connecting several, less powerful pumps and running them at a constant speed – even during idle times. But what if load locks for inline coaters in the architectural glass, solar, display and other markets, could be made more efficient thanks to fewer, more powerful pumps that “knew” when to run hard and when to save energy? That, in a nutshell, is what motivated Leybold to create the world’s first intelligent vacuum pump: the DRYVAC PowerBoost system.
