Ventilation system guarantees sterility in the cleanroom
No germs are allowed to enter the cleanroom. Air flows and air exchange rates are strictly regulated. A ventilation system ensures a constant positive pressure in the room so that it remains sterile even when doors are opened. If the power, and therefore the ventilation system, fails for just a few seconds, sterility in the room can no longer be guaranteed. "Then we would have to dispose of the batches of medication that we are currently filling," explains Kai Schumacher.
The 30-something has been with Vetter for six years and is rarely seen in the cleanroom. His home is a few stairs away in the company's "technical cellar". This is where he has once again had mtu Kinetic PowerPacks installed. "Because they simply work well," he says.
mtu Kinetic PowerPacks: Kinetic mass storage ensures constant availability
What makes them special is that they are immediately ready for use even without a battery and can compensate for the smallest irregularities in the power grid. For this purpose, mtu Kinetic PowerPacks have a constantly rotating kinetic mass storage unit. This is coupled with an mtu combustion engine and a synchronous generator which, depending on the operating mode, is also motor-driven and thus compensates for the power factor of different consumers.
As long as the public power grid is running, the kinetic mass storage device - in this case a flywheel - is driven by the generator, which works as an electric motor in this operating state. The heavy kinetic mass storage serves as an "energy battery" that stores the energy and then makes it available when the power fails.
