CENTRALISED SYSTEMS BECKER

VARIAIR Systems (VAS) are intelligent pneumatic systems for entire production processes.

The VAS can be set up directly next to a machine or installed in a separate room. As a result, the pumps no longer have to be situated directly next to the various machines and can instead be installed in a sound-insulated cabinet. In printing plants, the VAS is the first system that makes it possible to combine the controller system for the vacuum and blast air supplies directly with the machine controller. The various air parameters can be set easily from the control panel of the printing machine. Instead of having to adjust each of the machine valves separately as was previously done, it now suffices to merely press a button on the control panel of the printing press.

All of the settings are stored and can be retrieved from the database for each new job:

  • No spoilage
  • Increased printing speed
  • Practically maintenance-free
  • Time and energy savings
  • Automatic settings for every printing material
  • No noise, no overheating

Central systems with a promise of success.

The VARIAIR Central System (VACS) from Becker provides a compact solution for supplying air to one or more production systems. This method of supplying suction and blast air supply is employed in a wide range of different places.

Whether in small businesses or for specific stages of production in large companies, the energy-saving VARIAIR Central System delivers suction and blast air that’s matched to demand. VACS ideally complements subsequent finishing operations in printing shops equipped with the VARIAIR System (VAS), e.g. on assembling, folding and inserting machines, etc.

VACS cuts noise in the work environment and reduces operating personnel exposure to high temperatures through the absence of direct heat sources. This is where VACS offers the major advantage of Becker’s modular control system VACON. It manages as many as four different pressure levels with no more than seven pump units each. The VARIAIR Central System obviates the need for additional pump rooms. Affording a high degree of flexibility, VACS uses short connection lines and costs little to install. All connected equipment is provided with a built-on frequency converter.

VACS is based on four different basic units with a wide range of accessories integrated in a cabinet. Of modular design, these cabinets can be extended at any time to ensure flexibility in accommodating growing production requirements.

Centralised Systems

Becker provides intelligent pneumatic solutions for one or several production machines.

In central pneumatic systems, multiple single pumps on separate production machines are replaced by just a few larger vacuum pumps and/or compressors in a separate room (control room, basement etc.). The units are connected to the production machines via pipes.

Central pneumatic systems provide your machines with on-demand vacuum and blast air, which means energy savings. Noise levels are drastically reduced in employee work areas.

Each pneumatic supply in a centralised system is equipped with its own frequency converter. Thus, the pneumatic requirements of each production machine can be continuously adapted for any given operating point. By average, frequency-controlled units operate at a relative speed of approx. 65%. Overall, this leads to significant energy savings over separate units and devices without speed controlling.

Our central pneumatic systems are always optimised for your specific requirements. Each system is designed and configured especially for the requirements of the given application.

Advantages:

No heat or noise emission in production area

In production facilities, workplaces are being subjected to ever more stringent noise and heat emission regulations. In centralised pneumatic systems, there is no longer a need for separate vacuum pumps and compressors. Employees are subjected to minimum levels of heat, noise and oil mist.

Lower energy requirements for air conditioning systems

Eliminating the many separate pumps leads to a significant reduction in convection heat. Thus, air conditioning systems are subjected to lower loads and consume less energy. By removing the exhaust outlets (and the accompanying oil mist) from the production area, the air quality is greatly improved in the production area.

Energy savings using VACON4/xxx controller

The central systems are controlled using the VACON4/xxx controller. The VACON4/xxx controller monitors and controls up to 4 different pressure or vacuum levels.

  • Installed into a control panel
  • No need for mechanical pressure switches
  • No need for reserve containers/vessels
  • Even pressure flow
  • Very low energy requirements
  • Automatic switchover of basic load
  • Even distribution of operating hours of units in central system
  • Central data access

Central maintenance area

In centralised pneumatic systems, you can inspect and service the pneumatic supplies at a single location. It is much easier to access and inspect these units than to having to travel to each single supply unit for this purpose.

Lower maintenance requirements

Plants without a centralised pneumatic supply system typically have multiple vacuum pumps and compressors from multiple manufacturers in production. The many different replacement and wear parts required for each separate system results in drastically increased logistics and becomes expensive for the plant operator. Generally speaking, vacuum pumps and compressors in centralised pneumatic systems are low maintenance and utilise many of the same parts and materials. This restricts the range of required parts to an absolute minimum.
