UK-based technology company Plumis is expanding U.S. access to its Automist residential fire sprinkler system, a move intended to grow its presence across the American market. The system uses a targeted water mist that the company states consumes up to 90% less water than traditional sprinkler systems.

Automist employs intelligent detection, combining early smoke sensing with thermal imaging to pinpoint a fire's source. According to Plumis, this allows for faster activation and deploys a fine water mist to suppress the fire, which can minimize the water damage often associated with conventional systems. The system has achieved third-party certification under UL 2167A.

Designed for modern homes, the wall-mounted units connect directly to a building's existing domestic water supply, requiring no separate tanks or major piping upgrades. Plumis is highlighting the system's suitability for a range of applications, including custom homes, accessory dwelling units (ADUs), renovations, and properties in areas with low water pressure or freezing conditions.

The company is supporting the U.S. expansion with a new dedicated website and an increased presence at industry events, starting with the 2026 NAHB International Builders’ Show.
