Busch developed a new concept: a central vacuum supply for all particle counters using two vacuum pumps, which operate according to the MINK claw vacuum principle. These are also equipped with an intelligent drive with a frequency converter, which enables the vacuum pumps to be regulated such that they permanently operate at the required performance, even if the process conditions change. In May 2014, two MINK MV 0040 D claw vacuum pumps were installed in the technical centre of the JCC and operated redundantly. This means that only one of the two vacuum pumps is in operation, while the other acts as a stand-by.
The two new vacuum pumps are programmed to maintain a precise standard flow of 28.3 litres per minute at the particle counters. Both vacuum pumps are connected to the building control system and constantly monitored, with any malfunctions immediately displayed. The vacuum system is in use around the clock, with the control system designed by the technical centre of the university hospital in such a way that the vacuum pumps operate alternately and therefore both spend the same amount of time in operation. In the event that one of the vacuum pumps malfunctioned, the control system would immediately ensure that the other pump springs into operation and the vacuum supply does not fail. A continuous and reliable measurement of the particles in the air in clean rooms at the Josè-Carreas centre for somatic cell therapy is imperative.
MINK vacuum system solution and its benefits for the customer
MINK claw vacuum pumps operate dry, meaning that they are free from operating fluids in the compression chamber and operate contact-free. Unlike dry-running rotary vane pumps, there is no wear, thanks to this method of contact-free operation. It is another reason why this type of vacuum pump permanently generates the required pumping speed. The operation without operating fluids and without wearing parts makes the MINK claw vacuum pump virtually maintenance-free. This new vacuum technology has been in operation at the José-Carreras Centre since May 2014, and so far, there have been no “flow alarms” in the clean room or any other malfunctions or disruptions to the vacuum supply. Furthermore, in the last 3 years since implementation of the MINK claw vacuum pumps no maintenance work has been required on the vacuum pumps.
