• insulating gas valves couplings – Synergy Power Systems

    When using the DILO coupling system a leak rate of better than 1 x 10-8 mbar l/sec. is achieved corresponding to less than 1 cm³ in 3 years. The DILO seal principle prevents the loss of gaz sf6 gas and moisture from penetrating the Sulfr hexafluoride gas system. DILO couplings will eliminate the loss of sf 6 gas by incorrect gas handling.
