Watchman SF6 Autofill - Monitor, Log, Report, Top Up, Maintain

Modtech, the inventor of the Watchman® line formerly sold by Solon Mfg., is now the direct supplier of the Watchman® products and services.

The Watchman® SF6 AutoFill continuously monitors and maintains SF6 gas density. Unlike any other device in the world, the AutoFill model combines patented technology and engineering expertise to safely and effectively replace SF6 gas while the breaker is energized. The Watchman® SF6 AutoFill extends the life of leaking assets by ensuring no outages due to loss of dielectric insulation.

The Watchman® SF6 Autofill may be connected to any high voltage switchgear or breaker to automatically and precisely monitor and maintain gas density thus eliminating expensive service calls and outages. A precise record of gas additions and losses is maintained and advance notice of changes in leakage rates is provided.
