SODECA PRESSURISATION CONTROL SYSTEMS
For staircases, lobbies and escape routes
SODECA pressurisation control systems have been designed in accordance with European standards:
EN 12101-6:2005
Standard for the design, installation, commissioning and maintenance of differential pressure systems, for protection against smoke in escape routes.
EN 12101-13:2022
Update of the previous standard EN 12101-6:2005 for the design, installation, commissioning and maintenance of differential pressure systems, for protection against smoke in escape routes. The use of one or the other standard for the design of a pressurisation system depends on the regulations in force in each country.
EN 12101-6:2022
Standard for testing the performance of the differential pressure kits used for protection against smoke in escape routes.
Smoke Control Method in the Event of a Fire
The overpressure smoke control method consists of pressurization by injecting air into spaces used as escape routes during a fire, such as staircases, lobbies, passageways, and lift shafts. This method is based on controlling smoke via the speed of the air and the artificial barrier created by an overpressure condition.
In accordance with the European standard on design, there are different classes of differential pressure systems in buildings, depending on their use and characteristics. Selecting and classifying the system for each specific case requires considering the building’s use, size, and established evacuation instructions in the event of fire. This choice will determine the necessary flow rate delivered by the pressurization equipment.
It is crucial to pay special attention to the choice of system, as different classes require different flow rates.
Response Time
The European standards of design and product of pressurisation systems require all systems be designed in a manner that the force to be applied on a door handle to open it does not exceed 100N and in a manner that makes it possible to respond in just a few seconds to the changing positions of the doors during an evacuation by increasing the supplied flow when a door is open and reducing it to limit overpressure inside the protected space when a door is closed.
SODECA systems are equipped with state-of-the-art, built-in
controls that meet the most stringent requirements and are extremely reliable in the face of changes in situation that may occur during a fire, and in “chaotic” evacuation situations in which doors between fire zones and in pressurised smoke-free areas are opened and closed at
random.
Our systems are capable of reacting quickly and accurately to
these changes, ensuring the required overpressure is always maintained (50 or 30 Pa depending on the standard of design that is used) in situations where doors are closed and maintain the required air speed in any open door situation.
This response capacity guarantees that the force used to open a door does not exceed 100N, as set out in European standards.

SODECA PRESSURISATION SYSTEMS FAQ's
Why are pressurization systems essential for staircases, lobbies, and lifts in smoke control?
Pressurization systems are crucial for preventing smoke from infiltrating escape routes such as staircases, lobbies, and lift shafts during a fire. By maintaining a higher air pressure in these areas compared to adjacent spaces, these systems ensure that smoke is kept out, allowing safe evacuation and access for emergency services.
How do pressurization systems work in staircases and lift lobbies during a fire?
In the event of a fire, pressurization systems activate to supply air into staircases, lift lobbies, and shafts, creating a positive pressure environment. This pressure differential prevents smoke from entering these critical areas, ensuring they remain clear for evacuation and rescue operations.
What specific challenges do lift shafts pose for smoke control, and how do pressurization systems address them?
Lift shafts can act as conduits for smoke spread between floors. Pressurization systems for lift shafts ensure that the air pressure inside the shaft is higher than in the surrounding spaces, which effectively prevents smoke from entering and spreading vertically through the building.
Are there different pressurization requirements for staircases, lobbies, and lift shafts?
Yes, the pressurization requirements vary based on the specific area and its function. Staircases typically require the highest pressure to ensure they remain smoke-free. Lobbies and lift shafts may have slightly lower pressure requirements, but all must be carefully balanced to prevent smoke ingress while allowing easy door operation.
What standards govern the design and installation of pressurization systems for staircases, lobbies, and lifts?
These systems must comply with standards like EN 12101-6, which provides guidelines for smoke control systems using pressure differentials. Additionally, local building codes, such as SANS 10400 in South Africa, specify the design, installation, and operational criteria to ensure effectiveness during an emergency.
Can pressurization systems be retrofitted into existing buildings?
Yes, pressurization systems can be retrofitted into existing buildings. However, this process requires careful planning and design to integrate the new system with the building’s existing architecture and fire safety features. Working with experienced engineers and compliance with relevant standards is essential for successful retrofitting.
How are pressurization systems for smoke control tested and maintained?
Regular testing and maintenance are essential to ensure these systems function correctly during a fire. Tests include measuring the pressure differentials across doors, checking the operation of fans and dampers, and ensuring that the system responds correctly when activated. Maintenance should be carried out according to a schedule that complies with local regulations and standards like EN 12101-6.
