Press Control Systems feature vacuum and blow pumps.April 8, 2010 -
PVBS 3 control systems and decentralized modules use compressed air-driven technology that enables recovery of up to 75% of energy used to power units. Decentralized system, which includes regulators for each unit on vacuum and blow pump module, enables printer to set pump values so they fit actual print job. Able to be fitted beneath press or catwalk, system is monitored via touchscreen operator terminals and program recipes for different printing assignments can be saved in control unit.

Eco-Friendly Vacuum and Blow Pumps with Control System: Boosting Productivity and Operational Reliability for the Graphics Industry
PIAB's new generation of control systems and decentralized modules - known as PVBS 3 - featuring vacuum and blow pumps, reduce energy consumption and boost profitability for the graphics industry.
"It's energy-efficient, reliable and almost maintenance-free. There's no better solution for the printing industry," says Armin Steger at PIAB's Application Center Graphic in Butzbach, Germany.
By using compressed air-driven technology - which makes it possible to recover up to 75 % of the energy used to power the units - instead of traditional electromechanical vacuum pumps, energy consumption is reduced, which means lower electricity costs and reduced carbon emissions.
The decentralized system includes regulators for each unit on the vacuum and blow pump module, guaranteeing that a minimum of compressed air is used. It enables the printer to set the pump values so they fit the actual print job.
The units are so compact that they can be fitted beneath the press or catwalk where they are most needed. That means more working space in the press hall, while loss of blow or suction power in the short hoses is much less than for longer vacuum and blow hoses.
PIAB's solution produces a lower temperature in the press hall - and therefore a significantly better climate for printing - than electromechanical pumps that generate heat.
"The air compressor unit is located in a room next to the press hall, so heat is generated there instead of around the press. If you install a heat recovery system you can supply heating or hot water to offices or other areas and thus reduce energy costs," explains Armin Steger.
By equipping all of the pumps with vacuum filters, the already small need for maintenance is reduced to almost nothing, while operational reliability improves significantly. In addition, there is a 5-year warranty for the vacuum and blow pumps.
The system is monitored safely and conveniently via one or two operator terminals with touch screens. You can use the touch screen to set the required vacuum and blow pressure for the pump modules.
Program recipes for different printing assignments can be saved in the control unit, which shortens start-up times on future print jobs and thus further boosts productivity.
PVBS 3 uses 15-30 % less energy compared with the previous PVBS generation. The system is equipped with the latest electronics and other finesses, but the price remains unchanged.
The PVBS 3 interface is specially designed for presses from manroland, KBA and Komori. "But the electronic bus interface is so open that it can be made compatible with most printing presses on the market," explains Armin Steger.
The control system can be installed on both new and old printing presses, and be combined with modules of vacuum and blow pumps. For existing presses a retrofit is required so that electronics and modules are configured to meet requirements.
PVBS 3 will be launched in the middle of March.
