Minimax MX 200 HFC-227ea Fire Extinguishing Systems

Clean agent protection for rooms with electrical and electronic equipment

Minimax MX 200 fire extinguishing systems use the clean agent HFC-227ea. Minimax describes it as particularly suitable for spaces with electronic and electrical equipment and as an economical solution for small and medium-sized rooms. The 50-bar technology of the system makes use of the characteristics of the agent.

HFC-227ea reduces the heat of the fire and stops the combustion reaction. It is stored as a liquid and becomes gas only at the nozzles, so it usually reaches concealed fire sources at once. It is neither corrosive nor electrically conductive, leaves no residue and is removed from the room by ventilation. Minimax notes that at its design concentration it presents no health hazard, which is why MX 200 installations also suit areas with high human activity.

50 bar technology and typical applications

In addition to the conventional 25 and 42 bar, the 50 bar configuration allows longer and more complex piping within the 10 second flooding limit. The agent can then be stored outside the protected room, so the room space stays usable for its purpose, for example for more server cabinets, and the agent stock can be serviced without entering sensitive areas.

Multi-zone systems share one stock for several rooms and release only into the affected zone through selector valves. The quantity is calculated for the largest protected space, and a reserve remains after a release.

What to confirm before ordering

Each system is designed for the project with DesignManager, so the quotation needs room dimensions and height, leakage and ventilation data, the number of zones, pipe routing and the control panel. If you replace an older system, give the agent and pressure of the existing one. The Minimax HELIOS AMX5000 aspirating smoke detector is one detection option on the same Minimax range.

Documents and quotation

The Minimax brochure PB12Ce (print run 05.15) is attached with single-zone, multi-zone and design details. Seven Star LLC is an independent supplier in Muscat; the brochure is an older print run, so current data is checked with Minimax during quotation. See Fire Fighting.
