iMist Fire Suppression System – STX12 & STX12-2 Overview
Both of the iMist systems are a pump based system comprising a pump unit, control system, water
supply connection, monitoring system, and closed head discharge nozzles. The Nozzles Spacings,
location and flow rates have all be approved and witnessed at the live fire full scale test scenarios.
iMist STX12 systems are an effective form of fire suppression working at a nominal pressure of 100
bar. The pressure, in combination with calibrated discharge nozzles produces extremely small
droplets which help attack all aspects of the fire triangle, thus leading to the suppression of a fire.
iMist use the same 57° Frangible bulbs as the traditional fire sprinkler systems, meaning that the
only way of activating the system is by concentrated heat, it won’t be set off by your burning the
The system is designed as a wet pipe system and so the pipe is normally charged with water at mains
incoming pressure. In the event of a nozzle operating, the flow is monitored and, after a short delay,
the pump started. Water is discharged as mist through the open nozzle.
More nozzles may operate over time dependant on the fire size, location and heat until the
maximum capacity of the system is reached.
