Full cone nozzles with protection cap, series 400/401

Full cone nozzles with protection cap

Series 400/401

Particularly uniform full cone atomization. The nozzle outlet is protected by a cap against dirt and minor damage. This falls off at a corresponding water pressure and releases the nozzle opening. The protection cap can be optionally secured to prevent loss.

Applications: Fire protection applications in hatch covers and preventive fire protection in cargo holds.

Deflector-plate nozzle, series 500.393

Deflector-plate nozzle

Series 500.393

Application: Deflector plate nozzles for fire protection on lifeboats.

The nozzle was designed to protect the outer shell of lifeboats against heat and fire. The water film is sprayed backwards so that the shell of the lifeboat is completely wetted and cooled with water. It eliminates the need for complex piping and a large number of nozzles.

Pop-up foam extinguishing nozzles, series 500.447

Pop-up foam extinguishing nozzles

Series 500.447

Application: Fire protection on landing decks.

The pop-up foam extinguishing nozzle and the rotating pop-up foam extinguishing nozzle meet customer-specific requirements for fire protection on landing decks. The inexpensive alternative with simplified construction (e.g. for hangars) dispenses with the rotation of the three central extinguishing jets.

The rotating pop-up foam extinguishing nozzle is increasing in importance due to the fact that crew levels on ships and unmanned offshore platforms are continuously falling. Specific applications: Helicopter landing platforms on ships (cargo, passenger, navy, yachts), offshore platforms, hospitals. Aircraft hangars, tank farms, special tank cleaning applications.
