Leakage
LD 300 leak detector
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 theses costs are caused by leakages in the
compressed air system. The air "escapes" unused. 1 leak with a diameter
of 1 mm = 270 EUR/year. The LD 300 will be payed off after 4 leakages.
