How fire dampers stop smoke from spreading during emergencies
When a fire starts, every second matters. The key to minimizing damage and saving lives is to prevent smoke from spreading. That’s where fire dampers prove to be effective – they automatically block the migration of smoke through ventilation systems.
How fire dampers fight smoke: working principles
But how exactly do these humble devices manage such an important task? It all comes down to simple mechanics. Fire dampers have thermosensitive elements that react to heat. When the temperature rises – usually above 72°C – they automatically shut off.
Let’s take the Vents KPDU, for example. This model can withstand up to 180 minutes of heat, with temperatures reaching 600°C. Even under extreme conditions, it still stands strong, sealing off the airflow and keeping the fire from spreading further.
Features of different types of dampers
Different buildings and systems call for different approaches, and that’s why you’ll find both mechanical and electric versions on the market.
Mechanical dampers, like the Vents KP-1, are the tried-and-true heroes of fire safety. They’re simple but reliable. The beauty of these devices is that they don’t need electricity. When the temperature crosses a threshold, a thermal fuse activates, triggering a spring to close the damper. It doesn’t matter if the building loses power – these dampers will still do their job.
Then there are the electric dampers, like the Vents PL-10. These are a bit more high-tech, offering remote control capabilities. The system allows building managers to close dampers from a central location – super convenient, especially in multi-floor facilities. Plus, they can easily integrate with other safety systems, giving you a fully automated approach to fire prevention. These dampers respond faster, which is critical in an emergency situation.
What’s actually important here?
Mechanical dampers:
- work independently of power supply;
- extremely reliable;
- easy to install, even for smaller projects.
Electric devices:
- can be controlled remotely;
- seamlessly integrate with other systems;
- respond quickly in emergencies.
Both types have their place, but choosing the right one really depends on the specific needs of your building. High-traffic areas, for example, might benefit from the more automated electric dampers, like the Vents KP-2, while smaller, simpler installations may require mechanical ones.
What to know about installation
If you don’t follow the installation guidelines, the system simply won’t work as it should. For instance, the Vents KP-1 dampers need a minimum of 200mm of space between each unit. Sounds simple, but if they’re too close together, problems may arise.
A quick checklist for installation:
- Stick to safety standards.
- Ensure the system is easy to maintain and access.
- Choose fire-resistant seals.
