How to ensure certification and maximum efficiency in fire protection for fire frames

SCENARIO FOR THE SECTOR
Fire protection within companies

The sector is concerned with fire safety for companies, with particular attention to protection against industrial fires.

In this context, the focus is on the need to ensure an effective system of water blades that wet a fire cloth in case of fire, with the specific requirement to keep the cloth constantly wet to prevent the spread of flames.

Fire prevention in the company not only preserves material and financial resources, but above all protects the safety of workers, promoting a safe and sustainable work environment that is crucial for the success and continuity of business.

THE PROBLEM

A manufacturer of fire protection systems is faced with the challenge of certifying a new product: a fire protection cloth designed to withstand fires and prevent the spread of flames.

The certification test requires that the fireproof cloth is constantly wetted by a water blade with a spillage of 6 liters per square meter per minute with nozzles at a distance of 0.8 m and a pressure of 2.2 bar.

PNR ITALIA SOLUTION

PNR Italia proposes an effective solution to face this challenge.
The proposal consists of the use of KHW nozzles in AISI 316L steel.

To ensure adequate coverage of the fire curtain size 3×3 meters, PNR Italia designs a system that includes a pipe positioned 30 cm above the cloth, equipped with 4 KHW nozzles and ZPM clamps to ensure a uniform distribution of water.
Considering that the angle of the spray is about 130°, by making them spray vertically and fixing them with a pitch of 80 cm, we derive that after 20 cm of fall overlap with a significant increase in the amount of water spilled on the surface to be wet.
