Vinzenz Murr relies on Vacuum 4.0 technology from Busch

Vinzenz Murr GmbH has been producing meat and sausage products for 120 years and is now one of the largest butchers in Munich and southern Bavaria. Since 2004 it has been supplying a centralised vacuum system from Busch Vacuum Solutions all packaging machines in the butcher's shop in Obersendling with vacuum. It consisted of a vacuum system with three R5 rotary vane vacuum pumps and a total of three vacuum boosters. The vacuum system was previously operated with a cascade control system, meaning that only as many vacuum pumps were working as were required for the current operation. 

With the relocation of the vacuum system to another room, Managing Director Alexander Brandl has decided to replace the rotary vane vacuum pumps equipped with standard motors by frequency-controlled rotary vane vacuum pumps, to be able to adjust the performance of the vacuum system more precisely to the actual requirements. This is because the packaging machines Products ranging from several kilos in weight to small portion packs for the self-service area. This means that packaging is carried out with very different moulds and therefore the volumes of the packaging chambers vary considerably. Due to relatively small quantities, the total volume of all packaging machines changes frequently and, as a result, so does the power requirement of the vacuum system.
