Quick Opening Differential System

NAFFCO HFC-227ea engineered fire extinguishing systems manufactured and designed by NAFFCO are developed as heavy duty, reliable equipment and easy to mount.

NAFFCO-227 360-psi Modular (Single Cylinder) Systems

A 360-psi modular system is a single cylinder system using welded cylinders from 67 to 592 lbs. pressurized with Nitrogen at 360 psi. It includes cylinder, dip tube, discharge valve with pressure gauge/switch, manual level release and the solenoid electrical actuator. The agent flows from the cylinder through a hose into the pipework, which ends with one or more nozzles.

NAFFCO-227 360-psi Centralized (Up to Three Cylinders) System

A 360-psi centralized system is a multiple cylinder system using welded cylinders from 67 lbs. to 590 lbs. pressurized with Nitrogen at 360 psi. For system using up to three cylinders, the first cylinder (master cylinder) is equipped with a manual level release and a solenoid electrical actuator and operates all the other (auxiliary) cylinders. All the cylinders must be filled with the same amount of agent. For centralized systems using cylinders of 190 lbs., 300 lbs., 430 lbs., and 590 lbs. the pressure in the master cylinder is directoed to the pneumatic head with rapture disc mounted on top of each auxiliary cylinder valve through a line of high-pressure hoses.

NAFFCO-227 360-psi Centralized (More Than Three Cylinders) System

A 360-psi centralized system with more than three cylinders is operated by a 3-liter pilot cylinder filled with Nitrogen pressurized at 1,450 psi. The pilot cylinder is equipped with both manual level release and solenoid electrical actuator. The pressure from the pilot cylinder is directed toward the auxiliary cylinder pneumatic heads through a line of hoses and bursts the discs of pneumatic cones. A single pilot cylinder can operated up to 40 cylinders.

NAFFCO-227 600-psi Modular (Single Cylinder) Systems

A 600-psi modular system is a single cylinder system using seamless cylinders from 12 lbs. to 300 bls. pressurized with Nitrogen at 600 psi. It inclused cylinder, dip tube, discharge valve with pressure gauge and switch, manual lever release and solenoid electrical actuator. The agent flows from the cylinder through a hose into the pipework, which ends with one or more nozzles.
