Busch launches the new VacControl vacuum gauge for the measurement of vacuum directly within packaging.
The new VacControl vacuum gauge from Busch is a completely new way of measuring the vacuum
level directly within the vacuum packaging and of monitoring and documenting the measured data
online.
VacControl constantly checks packaging integrity and records and archives the results.
The VacControl gauge is simply placed in the packaging alongside the product contents prior to
processing. This is possible on all vacuum packing machines, without interrupting production. As
the air within the packaging is evacuated, the VacControl automatically records the pressure profile
with 1,500 individual values. During packaging, these values can be remotely transmitted to a
computer via Bluetooth and presented as a graph on the computer. The times between the
individual measurements can be varied and thus be optimally adapted to the packaging process.
1500 individual measurements can be spread out over a period of up to five hours, checked and
documented. Thereby even the smallest leaks in the packaging will be detected.
VacConnect software allows the pressure profile to be simply displayed graphically on a PC. These
graphs can be saved as Excel files and their presentation can be individually optimised using the
extended graphics features on VacConnect. Up to ten VacControl gauges can be separately
operated by one PC. The memory feature allows for the measured data of up to ten graphs to be
stored in VacControl and later transmitted to a PC.
The VacControl gauge is robust and withstands temperature and humidity. It fits into every vacuum
package thanks to its compact dimensions. With a measuring range of 1mbar(a) to atmospheric
pressure, VacControl covers the entire pressure range of the evacuation process during
packaging. Measurements can be made in millibar, Torr and PSI.
The units used can subsequently be changed on the PC using VacConnect.
VacControl's simple operation allows vacuum within packaging to be checked in short cycles and
therefore packaging quality is constantly monitored and documented.

The wind blows on the coast, the vacuum comes from Maulburg
Maulburg. Last year, Busch supplied a large number of vacuum systems for production of wind turbines worldwide. The call for environmentally-friendly energy production is becoming louder, and this in turn means that there are more and more wind energy farms everywhere. Above all, so-called offshore wind farms, with increasingly large turbine installations, are currently being built off sea coasts.
Manufacture of rotor blades requires vacuum pumps produced by Busch, based in Maulburg, Germany. The rotor blades for wind turbines are made of plastic. This plastic flows into the mould in liquid form under vacuum and then cures. The rotor blades, measuring up to 60 metres in length, require correspondingly dimensioned vacuum plants. Busch produces these plants individually and according to customer requirements.
In recent years, a number of firms have been established on the German North Sea and Baltic coasts that specialise in production of such offshore wind turbines. They all trust in the reliability of vacuum technology from Maulburg. The failure of a vacuum plant during the curing process, which lasts several hours, can cause a loss of several hundred thousand euros. The reason why all these companies have been established directly on the coast is obvious: due to their size, the up to 60 m long rotor blades cannot be transported on roads. They must be loaded from the production hall directly onto ships that bring them to the offshore wind farms. The plants are assembled directly on-site. Once the plants are assembled in the water, they have a height of up to 180 metres above the water level. Busch mainly delivers vacuum plants for these applications to Northern Europe, India, the Far East and North America. Busch engineers in the respective countries consult customers on site and provide technical support for the plants, and at the same time stay in close contact with the specialists in Maulburg.
