Vacuum centralization means to generate pneumatic energy with one source only, instead of several split rooms. This was the solution preferred by a renowned hollow glass manufacturer in Mexico, which decided to design its new glass plant right from the very beginning. The customer chose two Pneumofore UV100 vacuum pumps equipped with PLC and HMI. The machines have been successfully commissioned during the last weeks at full customer’s satisfaction. The Variable Speed operation of these large pumps allows to adapt – fast and precisely – to the vacuum demand coming from the production. Once the vacuum level is set, here at 350 mbar(a), the rotation speed of the machines changes according to the number of lines in operation. Furthermore, the vacuum flow requirements can change in case of a job change. The extraordinary capacity range goes from 1.900 m3/h up to 12.800 m3/h. Moreover, the indications provided by Pneumofore during the construction phase were completely followed by the local engineers resulting in a generous accessibility during the rare maintenance tasks, scheduled twice per year only.
