Gas Fire Suppression Systems
MPH Systems
Novec 1230, HFC-125, FM-200, HFC-318
Automatic Gas Fire Suppression Systems featuring MPH cylinders are designed for extinguishing Classes A, B, C fire as well as live electrical equipment.
Gaseous extinguishing agents are used in MPH cylinders: Novec 1230 (FK-5-1-12), Halons (HFC-125, FM-200, HFC-318).
Agents is stored in cylinders under pressure of replacement gas – nitrogen.
MPH cylinders have two modes:
- Stand-by (storing agent)
- Active (releasing agent)
When in stand-by mode cylinder is filled with agents and connected to automatic monitoring and control system
In active mode after receiving an initiating impulse from pneumatic or manual actuator locking device opens releasing agent into distribution pipeline, and agent discharges into the protected room through the nozzles.
The following types of MPH cylinders are manufactured:
