Diverse design capabilities while upholding the highest level of fire protection engineering principles is what separates janus from our competition.
There shall be sufficient high expansion foam concentrate and water to allow continuous operation of the system at the design density for 25 minutes or to generate 4 times the submergence volume whichever is less but in no case less than enough for a 15 minute discharge.
Foam is a soft substance that is added to the water with a percentage of 3 to 6 this substance separates the surface of the fire from the air and thus reduces the oxygen level by 15 and then the fire is extinguished.
