SIEX SMS (small spaces)

The SIEX HC clean agent system is adapted for small enclosures. Specifically designed to protect small spaces such as vehicles, buses, waste disposal trucks, electrical panels and telecommunication servers. There is a growing trend to install this type of device in order to minimize any fire damage without the need for large extinguishing equipment.

SIEX-SMS uses FM-200® and HFC-125 gases as extinguishing agents. Both gases are suitable for class A, class B and class C or A+ fires. It is stored as a compressed liquefied gas in small pressurized cylinders and can be installed in almost any location. The cylinder is connected to a very simple distribution network. Manual activation can be local or remote.

The release can be activated by anyone operating the machinery or using the protected enclosure. Remote activation is by a push button associated with the panel which controls the extinguishing system. The system complies with ISO 14520, UNE 23573 and NFPA 2001 standards.
