Air without idling

Supplier: BOGE Compressors (Australia)

New BOGE airtelligence plus controller for combined compressor systems helps save energy.

The newest member of the BOGE airtelligence product family places intelligent and consumption-dependent control of companies' compressed air production in the hands of the user - preventing expensive idle times. The resulting boost in production efficiency markedly reduces energy use and opens up a significant savings potential for businesses. 

BOGE airtelligence plus allows you to control any combination of up to six different compressor makes, models and performance classes in a combined compressor system.  A clear 4" colour display screen shows the operating states of the various compressors as well as important readings such as the system pressure and pressure switch points, and allows intuitive operation even of complex control processes.

Compressed air to order

Easy though it may be to operate, the processes which the controller regulates in the background during compressor operation are far from straightforward.  A pressure sensor detects whether, and how much, compressed air is needed.  The user can programme the control to turn on, or turn off, previously defined compressors if certain consumer load profiles are identified. This ensures that the most cost-effective compressors for the required amount of compressed air are invariably the ones in operation. So if a lower volume flow is required during fluctuating demand, the combined compressor system is parameterised so that a small variable-speed compressor is switched on. If a large quantity is required, for instance, if a large single consumer load with a steady level of consumption is switched on, a larger compressor with a fixed speed is given the go-ahead.  

This marked increase in efficiency has two clear benefits for users: energy costs sink - even though the quantity of compressed air supplied remains constant. And not only that, maintenance and servicing costs are reduced too – as airtelligence plus ensures that the various compressors are run at their most efficient duty point.

Easy installation
BOGE compressors can communicate directly with airtelligence plus using a standard RS 485/Modbus BUS interface. This helps when compressors are put on stream and is also an advantage when existing air compressors are upgraded. Previous generation controllers can benefit from interface modules which make it easier to link in the compressors.

Airtelligence plus is supplied ready-to-install in a metal cabinet for wall mounting; models are available for pressure ranges up to 16 bar and up to 50 bar. The 7 day timer provides 50 channels which allow the compressors' workload to be freely programmed.  This makes it possible to achieve not only base load switching but also, for example, to programme customised profiles for overnight switch-off times or weekend shifts with reduced compressed air demand.
