Protect your building from fire with a water mist system

Waster mist solution

First appearing in the maritime industry, water mist solutions are now present in many land-based applications in both tertiary and industrial environments.

The systems are suitable for fast and effective equipment protection (transformers, generators, production machines, …), as well as whole buildings.

Preliminary qualification tests guarantee a performance at least equal to that of traditional sprinkler systems.

By diffusing very fine droplets of water at high pressure (above 50 bar), the Uxello water mist solution provides optimal protection against fire. The benefits : to absorb the maximum heat released by a fire in order to extinguish it, while also consuming less water.

A question of weight and size

The systems offer the advantage of being much more compact and lightweight than conventional sprinkler systems. The small diameter of the pipes (Ø40 mm vs Ø200 mm for example) allows the assembly of networks in small or tight spaces.

Similarly, the limited size of the components facilitates the positioning of the water source.

Fire protection that uses less water

Depending on the type of risk, water mist can control or extinguish a fire by consuming 2 to 10 times less water than a sprinkler system.

Extinguished water must be reprocessed. Less water means a lower processing cost. This is even more true in the case of sites using high risk substances (pharmaceutical, chemical, nuclear etc).

When to choose water mist fire protection system?

The water mist system must be adapted to the risk and protection required, to the expected performance objective and to the different constraints of the project.

Engineering developed by Uxello Special Risks makes it possible to optimize this solution.

Beyond water-related issues, some sectors benefit from having less cumbersome and heavy facilities.

For example :

  • hotel rooms with false ceilings and limited space.
  • buildings that have not been designed to allow fire protection installations (problems of space and / or structural integrity).
  • Renovation of historical monuments in which the discretion of the facility counts.

Advantages of fire protection for data centers

The entirety of a data center can be protected by a water mist system. A centralized water source will protect technical premises and computer rooms, including ventilated and / or permanently air-conditioned areas, from fire.  A single fire suppression system for the entire building facilitates maintenance and operation.

Flexible water mist systems adapt to the urbanization and the specific evolutions of data centers.

Data centers also have an obligation to continuously provide a service.  The data center remains functional even during the use of the mist system (with ventilation / cooling of the various processes in particular). The water mist solution has the advantage of being able to be put back into service quickly after tripping.

Well being at work

The necessary move took place due to the current site becoming too old and too small for the growing business unit.
At Hénin Beaumont, everything has been redesigned to offer the staff a more welcoming site, thus improving well-being at work. The new site offers as bright open spaces, designer furniture and green plants.
Encouraging a warmer and friendler place to exchange, the teams benefit from relaxation spaces, designed in tones of relaxing greens.

Uxello Services Ile-de-France sets up in the South-East of Paris

This coexistence will reinforce existing links with the VINCI Facilities teams, specialists in multi-technical and multi-service maintenance; the objective being to multiply common offers.

Being closer to its tertiary and industry customers in these departments, Uxello will be able to optimize its travel time and thus offer even more attractive rates.

The ambition of Uxello Services Ile-de-France is to gain new customers in the logistics and airport infrastructure sector, thanks to its success at Roissy airport.

The next step will be to open by 2021 a new company in South East of Paris.

Fire protection : The 3 benefits of the new APSAD R5 fire hose rule

Improved sizing of facilities

While the regulation provides that 2 fire hoses must be able to reach any point of a site, the simultaneous operation of 4 fire hoses was imposed. Today, the APSAD R5 standardizes its requirements and only the operation of 2 fire hoses is necessary. The speed of water circulation in the pipes has also been increased from 3m/sec to 6m/sec.

Benefits of these changes:

  • new installations will be smaller (pipe diameter, water source capacity, water reserve, etc.),
  •  installation and hardware costs will logically be lower,
  • the weight on ceilings will be lighter, a benefit in building design for example,
  • lighter installations generate less fatigue and musculoskeletal disorders for our assemblers

Improved Precision

The requirements related to the network support have been deepened and clarified, for example points of attachment and their spacing, quantity, dimensioning, mechanical resistance etc.

The APSAD R5 also goes into much more detail regarding requirements related to maintenance, in particular for parts, and is centered on the obligation of result more than on the means to be implemented.

Improved chance of obtaining the certificate of conformity

All premises in a building must previously have been protected by fire hoses. Under certain conditions, the new rule APSAD R5 allows for exceptions to smaller premises (electrical rooms for example) and premises made of fireproof materials.

It is also now possible to limit protection to certain buildings or premises on a site, for example those essential to the activity. These exceptions require a certificate of compliance, which was not the case before.

Released in September 2018, the APSAD R5 rule will be enforced on 1 June 2019. Uxello nevertheless encourages you to put into place this new regulation now! For more information, contact one of our experts.

Uxello protects the future Vinci head office

To protect the future VINCI headquarters, called the Archipel, Uxello will install 3 400 sprinklers spread over five underground levels, including four in the car park, a delivery area, the restaurant area and the auditorium.

Located in Nanterre, the future head office will bring together the VINCI Group’s different business divisions into five interconnected « islands ». The Archipelago will be a reflection of the Group’s dynamic, providing an information sharing environment between employees, partners and citizens alike.

Uxello Tertiaire Ile-de-France will carry out this project in BIM (digital 3D model). Construction begins in March 2019.

Supporting agri-food with our fire protection solutions

CFIA – an event not-to-be-missed for Uxello

Uxello will be at the CFIA trade fair in Rennes from 13 to 15 March 2018. Join our teams in hall 10, stand G44 / H43, alongside VINCI Energies companies, experts in the field of agri-food industry.

For more than 20 years, the CFIA has been the major event for agri-food industry in France. It includes 1,450 exhibitors offering Processing, Packaging and Ingredient Solutions.

Uxello brittany is APSAD I4-NF285 certified

Certification for your protection

In addition to the IF1, E1 (installation service, maintenance and periodic checks of sprinkler systems) and J5-F5 (installation, validation and maintenance of fire hoses) certifications already obtained by UXELLO, this certification should accelerate the development of its overall service offer.

Thanks to this certification, Uxello is now in the preferred company for all fire-fighting systems such as sprinklers, fire hoses, fire extinguishers, smoke extraction, BAES (emergency lighting unit) and fire doors.

The certification policy continues to encourage new challenges including moving towards the next step of implementing the APSAD N17 certification for natural smoke extraction.
