Kidde ADS HFC-227ea Engineered Clean Agent Suppression System

Clean agent protection for larger hazard areas

The Kidde ADS with HFC-227ea is an engineered clean agent suppression system that Kidde Fire Systems developed for larger enclosures and longer agent flow distances. According to the manufacturer’s sell sheet, the Advanced Delivery System discharges at mass flow rates 2.5 to 3 times faster than a standard clean agent system, which allows longer pipe runs in complex layouts with smaller pipe sizes.

Technical specifications

What the sell sheet says about performance

The manufacturer highlights five points: increased agent flow rates and distances for larger hazard areas, smaller piping diameter that cuts installation cost, flexible design, higher cylinder fill capacity, and directional valves for protecting several enclosures from one agent supply. It describes clean agents as non-toxic when used in compliance with NFPA 2001, effective on Class A surface fires, Class B flammable liquids and Class C electrical fuels, and removed by ventilation afterwards.

This is a design-engineered system, not a catalogue item sold from a single part number. A supplier needs the room volume and temperature, enclosure integrity, the required design concentration, pipe layout and cylinder locations before cylinder quantity, fill weight, valves, nozzles and control equipment can be defined. The sell sheet lists the control unit, detection, cylinders, notification devices and manual pull stations as parts of the integrated system. Kidde panels such as the AEGIS-PHX and ARIES range are described in their own datasheets as controlling ADS clean agent systems.

A single sell sheet does not give nozzle data, flow calculation results or cylinder sizes, so this page is a system overview. Exact part numbers for cylinders, valves and nozzles must come from the manufacturer’s design documents. Installation, commissioning and room integrity testing are performed by a qualified fire contractor.

What to confirm before ordering

Send the protected volume, the number of enclosures, the agent required (HFC-227ea), the preferred approval basis such as UL, FM or USCG, and the project specification. For spares or recharge, the nameplate data and the fill weight are needed, as with the Kidde FM-200 200 lb cylinder listed on this site.
