compressed air is the most expensive form of energy in production plants! many companies are not aware of the fact that the generation and treatment of compressed air accounts for up to 20% of their overall energy costs. continuous monitoring reduces on-going operation costs, cuts investment costs for new compressors and ensures availability round-the-clock.

» To ensure efficiency

Youcanpermanentlyrecord,monitorandoptimizetheeffectivenessandefficiencyofyour compressed air generation and treatment processes.

» Din en50001

The DIN EN50001 power management system requires » increased energy efficiency and reduced energy consumption » the use of compressed air monitoring when used in heating, ventilation and

air conditioning applications, as well as documentation in production lines and processes The Austrian Energy Agency estimates average potential energy savings of 10 - 20% following certificationtoDINEN50001.

» To DeTecT leaks

25 – 40% of the compressed air generated is lost through leaks. Consumption of compressed air in a system that is switched off is a clear indication that there is a leak. A hole with a diameter of 3 mm (0,12“) produces annual costs of around € 3,000.- ($ 4,250,-), at7bar(102 psi) for example.
