RM AirSeT uses pure air yet retains or advances the functions and advantages of traditional SF6 GIS MV equipment. This SF6-free technology enables grid decarbonisation, helping hit sustainability targets. Pure air has no global warming potential and produces zero toxic by-products in breaking. It also reduces the potential impact of more stringent future regulations. RM AirSeT has received the Green Premium eco-label.

24/7 connectivity boosts GIS uptime, while the optional Easergy T300 RTU enables smart grid monitoring and control. Built tough, the SF6-free RMU uses high-performance components such as the CompoDrive operating mechanism and is sealed-for-life to preserve live parts from ambient conditions. Additionally, the MV switchgear offers scalable architectures, plug-and-play motorisation, and familiar operation, keeping the traditional 3-position switch and switch-fuse.

RM AirSeT offers a wide range of functions, including a switch, vacuum CB, and a compact switch-fuse – a first for an SF6-free GIS MV switchgear – in a compact footprint. These functions can be mixed and matched on order. Optimised for operation and maintenance, the smart RMU offers 24/7 asset health visibility, with thermal and environmental monitoring, plug-and-play motorisation, and end-of-life peace of mind with no gas recycling required.
