About us

In 1951 the development of a metal-to-metal sealing principle without any intermediate seal compound for high pressure tube unions laid the ground for a modern and innovative company. DILO is the leading manufacturer of SF6 gas handling equipment looking back on a 50 years’ experience. Recently added to DILO’s product range have been units for the handling of alternative gas mixtures. Today, switchgear manufacturers and energy utilities worldwide rely on DILO as a major technology partner in gas handling.

Technology and environment in harmony is the clear commitment of DILO towards customers and partners all over the world. This demand for ecological responsibility is also guaranteed by our product strategy with in-house production and quality “Made in Germany”.

A network of approx. 65 agents worldwide provides our customers with advice and technical support on site.

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.

SF6 gas valves and fittings

SF6 gas valves and fittings

Whether for medium or high voltage switchgear or gas-insulated lines (GIL): Our products always meet customers’ requirements. The DILO sealing principle prevents the loss of SF6 gas and moisture from penetrating the SF6 gas system. DILO couplings will eliminate the loss of SF6 gas by incorrect gas handling. Thanks to their reliability, quality and durability DILO couplings are the world‘s most widely used connecting system for SF6 switchgear.
