A safer tomorrow starts with SEM-SAFE®

It is crucial that high-rise buildings are fully and properly equipped to handle a fire situation. In high-rise buildings, the access for the fire fighting crew can be very difficult, especially on the last levels of the buildings. Also evacuating people presents challenges and limitations.

Having a fixed high-pressure water mist system installed in high-rise buildings can make the fight against fire more efficient, with the ultimate goal of saving lives and limiting property damage.

Imagine a fire fighting system that can put out the fire in seconds, with minimal consumption of water, giving the best possible protection.

With SEM-SAFE® – the unique high-pressure water mist system from Danfoss
– that is what you get.

By using pure water, the high-pressure water mist technology used by the SEM-SAFE® system is harmless to humans and environmentally friendly. Its reliability and efficiency has been successfully proven in rigorous fire tests. 

The intelligent use of water

How does it work

For a fire to survive, it relies on the presence of the three elements of the ‘fire triangle’: oxygen, heat and combustible material.

The removal of any one of these elements will extinguish a fire.

The SEM-SAFE® high-pressure water mist system goes further. It attacks two elements of the fire triangle: oxygen and heat.

The uniqueness of high-pressure water mist is that it combines the suppression effect of gas and sprinkler systems. As well as removing the oxygen like a gas a gas system it simultaneously cools the fire like a traditional sprinkler. The cooling effect additionally lowers the risk of re-ignition.

A unique fire fighting system

The SEM-SAFE® high-pressure water mist system is a unique fire fighting system. When water is forced through nozzles, at high-pressure, a super-fine mist is formed that has a two-fold extinguishing effect. As well as cooling the fire like a traditional sprinkler, it simultaneously starves the fire of oxygen like gas systems. When the mist comes into contact with flames, it evaporates and expands minimum 1,700 times. The dense vapour created displaces the flames and quickly extinguishes the fire.
