Fire Extinguisher Refilling Process

The Fire Extinguisher is manually discharged / fired and emptied.

The extinguisher is then dismantled completely; cylinder is de-stressed.

The cylinder then is made to undergo a Hydro Static Pressure Test at 30kgf cm sq for 2 minutes to check for leaks and the burst capacity.

New extinguishing agent (powder, gas, water or foam) is filled in the cylinder through a vacuum based process that fills the cylinder with exact quantity of extinguishing agent.

The cylinder then is made to undergo a Hydro Static Pressure Test at 30kgf cm sq for 2 minutes to check for leaks and the burst capacity.

New Discharge fitment mechanism including all new rubber seals, O rings, and hose pipe (EPDM with 50 kg burst capacity) are attached.

Fire extinguisher is charged (pressurized) with 99.99% pure nitrogen mixed with helium.

The Fire Extinguisher is then made to go through Leak tests. The first is an inverted beaker test in water. The extinguishers also undergo a Mass Spectro Meter Helium Leak Detection Test which is the most advanced leak detection technology available currently in the world.
