Cost saving

In Germany 60,000 compressed air plants use 14,000,000,000 kWh

electrical energy per year. 15 to 20% could be easily saved

(Peter Radgen, Fraunhofer Institut, Karlsruhe). Most of these costs

are caused by leakages in the compressed air system. The air

"escapes" unused. 1 leak with a diameter of 1 mm causes costs

of approximately 270 EUR/year

The leak detector LD 300 (please see page 40) will be payed off

after 4 leakages
