Busch launch new VacControl vacuum gauge for the measurement of vacuum directly within packaging

Worldwide first from Busch: VacControl is the first vacuum gauge to measure the pressure within packaging and transfer the measured data directly to a PC via Bluetooth.

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

 

New generation of vacuum pumps

Busch has launched a completely revamped new generation of rotary vane vacuum pumps in the R 5 series. Three pump sizes with a suction capacity of 10, 16 or 21 cubic metres per hour produce an ultimate pressure of 0.5, 1 or 20 hPa (mbar), depending on the version. All sizes and versions offer stable performance characteristics, i.e. a high suction capacity is guaranteed even in the working pressure range. Thanks to their extremely compact design, these vacuum pumps are suitable for an installation in very confined spaces. A standard non-return valve in the suction pipe prevents ventilation of the recipient if the vacuum pump is turned off. The new R 5 rotary vane vacuum pumps are each driven by directly flanged standard motors. The main fields of application are vacuum packing machines, food processing machines, transportation and lifting devices and the plastics industry.

 

Busch R 5 rotary vane vacuum pumps are available with a large range of volume flow rates from 6 to 1,600 cubic metres per hour. The proven vane principle has been standard in numerous industrial sectors for many years. R 5 rotary vane vacuum pumps are very rugged, operationally reliable and have a high maximum tolerable water vapour inlet pressure thanks to the integrated oil circuit. All R 5 vacuum pumps are equipped with an oil separator as standard. This is fitted with air de-oiling elements that were especially developed for these vacuum pumps. This guarantees clean exhaust air.

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.
