Innovations are characterised also in vacuum technology by improving the degree of efficiency and savings in the energy consumption. Specially designed vacuum systems offer significant customer benefits, such as Oerlikon LEYBOLD vacuum on the occasion of the thermal process / METEC in Dusseldorf shows. The reliable generation of the required vacuum level has the top priority in vacuum pumps and systems for a smooth operation of the vacuum system is essential. The increasingly important requirement to conserve energy, may cause no restrictions in the productivity of the plant. Nevertheless, vacuum pumps and pumping systems to be interpreted are that they comply with the current standards of energy efficiency. The fight against global warming, the increase of greenhouse gases, as well as the limitation of CO2 emissions are the introduction of the European Directive 2005/32/EC by the European Commission based. These and other complementary policies form the consuming part of ecological design requirements relating to energy products, which a higher level of efficiency is required.

Several new or revised technical regulations are now taken into account in the development of new products. The influences of these developments have impacted recently also on the construction and the design of modern industrial furnaces. Modern vacuum furnaces with optimized vacuum systems work much more efficient when compared to older furnaces. More mechanical pumping systems instead of inside steam jet systems used in modern steel degassing systems. Here, too, modern vacuum pumps have proven themselves.

In the vacuum area, the usual high degree of reliability is achieved today primarily through the use of conventional technologies, such as oil-sealed lock slider or rotary vane pumps. In addition modern and highly reliable technologies have changed, such as proven dry compacting screw pumps, even under the harshest conditions. Screw pumps represent the current standard for dry-running pumps with variable rotor pitch. The continuous compression along the screw minimizes energy consumption.
