Kronos Titan, a manufacturer of titanium dioxide, took advantage of these benefits at its Nordenham plant. Quick action was called for after a screw compressor failure in the vacuum station because, with the remaining three compressors, a backup was no longer available. AIR delivered a type CVI 4400 rental unit at short notice. The installed Aerzener single-stage VML 60 screw compressor achieves a maximum flow rate of 73 m³/min in a vacuum environment of -700 mbar during vacuum operation. With this performance data, the unit offered enough capacity to replace two of the existing screw compressors. This simultaneously presented the possibility of inspecting the old compressors one by one. During the first inspection, however, the operator decided not to invest any more in the old compressors. AIR quickly supplied a second rental compressor so that the entire vacuum station was operated with both CVI-4400 rental compressors.
Both compressors were fitted with a process-controlled suction-pressure regulator, which made it possible for the system to deliver high load capacity results and a new vacuum station for the Nordenham plant could be planned.

"The hired compressors maintain our production and help us to establish high load capacity values for that station. In addition, AIR is very flexible and, if we need it, we have their immediate support."
