Wittig and Elmo Rietschle Vacuum Solutions by Gardner Denver

Producing glass, and especially hollow glass (i.e., bottles or other types of hollow containers), is a fairly complicated operation. This is why it is extremely important to use the right tools. Such as Wittig and Elmo Rietschle vacuum compressors from Gardner Denver, which are considered the world’s number one thanks to their robustness and reliability. These machines guarantee maximum performance combined with lower operating costs, thanks to their truly above-average mechanics and technology. Let’s take a closer look at how these wonderful vacuum pumps work. The rotary vane compressor consists of a single rotating component on which the aluminum vanes act by centrifugal force. The injection of lubricating oil ensures smooth running, sealing of the compression cycle, and protection against oxidation and wear. Excess oil in the compressed air can then be easily removed through an efficient coalescing oil separation system. Gardner Denver compressors and vacuum pumps, under the Wittig and Elmo Rietschle brands, truly represent the best on the market, both in terms of durability and reliability, but also and above all in terms of overall savings in consumables and all auxiliary services. This means not only electricity for powering the equipment, but also liquids such as cooling water, various lubricants, and inert waste such as bearings, gaskets, and filters. Gardner Denver is also synonymous with tradition: the first patent for rotary vane compressors was filed in 1908 and signed by Witting (now Gardner Denver). That patent still forms the basis for much of the technology used to generate vacuum or compress air in modern machines.
