ARTICLE: Marioff HI-FOG® System Protects the Warsaw Spire Office Building Complex in Poland
25 August 2017

The Warsaw Spire is a three-building office complex in Poland, constructed by Belgian real estate developer, Ghelamco Group. With the main tower standing 220 meters tall, it is the second tallest building in Poland and the 14th tallest building in the European Union. Such an iconic building certainly needs a state-of-the-art fire suppression system, which is why the HI-FOG® water mist suppression system was chosen to help protect the Warsaw Spire.

HI-FOG uses up to 90% less water than traditional sprinkler systems without compromising firefighting effectiveness. Using high pressure and specialized sprinkler spray heads, HI-FOG converts water into small droplets, which increases the overall surface of the water. These small droplets absorb heat more quickly and cool the source of the fire more rapidly, preventing the fire from spreading. Most importantly, the quick control and suppression of the fire plays a large role in assisting a safe evacuation.

The pump unit provides pressurized water from the lower levels of the building to the top floor, the 49th story, with no intermediate pumping stations. Water is fed to the system from two tanks equipped with automatic refill, ensuring the 60 minute discharge duration required by NFPA.

Poland’s fire safety regulations contain extensive requirements for passive fire protection in high-rise buildings. Installing an active fire protection system made it possible to compensate certain structural requirements without compromising safety. Through a consultant, simulations showed that the capabilities of a HI-FOG system, allow great cost savings in passive protection. More specifically, the structure fire rating of over-ground levels, in both the building shell and core, could be reduced by 25% compared to the requirements applicable for traditional sprinkler protection.

“As the General Contractor, we appreciate HI-FOG’s flexibility, smaller dimensions and ease of adaptation,” said Arnold Neuville, General Technical Director of Ghelamco Poland. “HI-FOG provides key advantages, such as minimal damages in the event of a fire and the ability to use the system in IT rooms.”
