SF6 gas service units

SF6 gas service units

SF6 gas maintenance equipment is manufactured acc. to state-of-the-art technology. All components used in SF6 circulation operate entirely without oil. The service units allow emission-free recovery, evacuation, purifying, storage and filling operations. Dependent on the model, SF6 gas can be recovered down to < 5 mbar or < 1 mbar and be stored either in gaseous or liquid form.

SF6 measuring devices

SF6 measuring devices

DILO’s range comprises measuring instruments that allow to confirm SF6 gas quality by monitoring the most important parameters such as decomposition products, SF6 concentration and dew point temperature.

Highly sensitive leak detectors allow quick tracing of even smallest SF6 leaks on SF6-filled components, and special room monitoring devices are available for permanent monitoring the air in SF6 indoor switch rooms.
