The overpressure ventilation technology
was invented during the eighties as an
appropriate element within fire protection
concepts for skyscrapers. The manufacturer
Systemair was instrumental in pushing the
development of an important improvement:
the electronic control for pressurisation
ventilation fans. This system provides higher
security for selfrescue and especially for the
fire brigade.

Important for save live and for a fast fire fighting
In the case of fire, it is not just for the people fleeing that
smoke gases present the greatest threat. It also puts the
rescue service personnel at risk and hinders their work.
Therefore, electronically-controlled overpressure systems
bring a new dimension to fire protection. With a simple
switch, the fire services can switch the supply air fans
to maximum power, limiting the need for mobile fans to
be used, or even making them unnecessary. This means
that electronic overpressure systems do not just support
self-rescue, but also provide additional protection against
smoke gases for the firefighting personnel, even at
high fire temperatures. They provide clear visibility and
generally make it possible to reach the source of the fire
more quickly.
Systemair is the leading company when it comes to
combining EC motor technology and frequency converter
control technology. An airtight building with low leakage
places higher demands on the planning and implementation of smoke extraction concepts. When designing an
overpressure system, the smoke extraction fans required
for smoke extraction in internal shafts play a significant
role. Uniting both systems – smoke extraction and the
overpressure system – into a functioning overall concept
is the latest development from Systemair.
The electronic control technology
Design example
The pressure differential system MUB-EC by Systemair
and its AC version needs no pressure relief unit due to
its control characteristics. It offers a complete solution
with fewer components and actuators for the pressure
differential ventilation in stairways and escape tunnels
as conventional systems. The system is also available
with smoke extraction function* in EC and AC design.
The complete system as well as its components meets
the requirements according to EN 12101-6 (Smoke and
heat control systems – part 6: specification for pressure
differential systems). The adjusted EC motor/AC motor
regulation unit guarantees a standardised regulation performance plus very low energy consumption
during the ventilation process.
Our MUB-EC centrifugal fan unit is used for residential
buildings up to eight floors. The capacity can be increased by parallel operation of two or more units. Higher
buildings normally require several supply air units installed at different positions in the stairway. The selfregulating EC control panel is connected to the fan unit
via a 0-10V-signal. There is just one standard 230 V cable
necessary for the control unit. The optional on/off switch
of the MUB-EC ventilation unit can be directly wired to
the 400 V power supply. Systemair‘s complete solution
includes periferic controls like, connections for smoke
detectors, manual call points and a fire indicator panel.
*Smoke extraction
Optional smoke extract fan certified to EN 12101-3 (Smoke- and heat
control systems – part 3: Specification for powered smoke and heat
exhaust fans).
Systemair will come up with individual solutions for
your applications.
Principle Pressure Differential Systems
Ten benefits of electronic overpressure systems
1. Faster self rescue
Fire escape stairways are recommended even if
other arrangements are permitted for escape and
rescue routes. People evacuation is faster through
smoke-free stairways
or stairways with less smoke – the panic risk can
be reduced.
2. Faster rescue by others
On electronic overpressure systems, the air supply
of the fans can be switched to the maximum air volume by a firefighter‘s switch. This enables pushing
back and leading smoke away, even at high fire
temperatures. The pressure in the stairway exceeds
the standards limitation, and a time-consuming
installation of mobile fans, allowing a clear view, in
many cases is unnecessary.
3. More flexibility during fire-fighting operations
Mobile fans placed in the building entry can become
a „tripping hazard“ for emergency task forces. With
the Systemair Pressure Differential System those
fans are not needed.
4. Higher security for emergency task forces
High air velocities combined with electronically
controlled ventilation reduces the concentration of
flammable gases and hot air in the zone on fire. This
reduces the risk of backdrafts and delays flashover.
5. Higher building protection
With the possibility of overriding the set pressure
with the electronic overpressure system a faster access for the firefighters is enabled. This reduces fire
damages which can be honoured by the assurance in
certain cases.
6. Reliability
Electronic overpressure systems are not affected by
wind loads, snow coverings or pressure changes due
to cold or warm supply air.
7. Reduction of construction costs
Openings for air outlets are not required. Control
dampers and additional weather protection equipment are usually not necessary.
8. Reduction of operating costs
No complex adjusting or cleaning of mechanical
control dampers.
9. Steady precision during life cycle
Electronic overpressure systems automatically compensate potential leakages due to normal wear and
tear of the building.
10. Architectural freedom
Huge air terminal devices or high roof fans are not
required.

Multibox EC
Thanks to a special control system, we are able to realise
a constant differential pressure in stairwells, using EC
fans. The constantly-measured differential pressure is
evaluated in the control system in real-time and compared
with corresponding setpoint values. The speed of the EC
fans is adjusted by the control system so that the setpoint values are adhered to in the stairwell. This prevents
the forces required to open the doors from getting too
high (max. 100 N). By selectively controlling the outflows

in the individual storeys, e.g. windows, the necessary
airspeed (at least 0.75 m/s, or 2 m/s) – depending on the
stairwell – is achieved by the open door between the
stairwell and the rooms on the individual storeys. The
light dome also serves to constantly exchange the air in
the stairwell and can also be used for daily ventilation as
required. Another option is to couple a smoke gas extraction fan to the system. The extract air fan is needed if
the outflow openings on the individual storeys lead to an
extract air shaft/duct which has too high a pressure loss.

Functional principle of IHS
|
New ideas and approaches when the physics offers almost no way out.
Depending on the stairwell, an air speed of 0.75 or 2 m/s
must be maintained at the open door to the room with
the fire. When the entry door is opened for people to
escape, the appropriate amount of air flows out of the
stairwell. This volume must be added once more. If the
flow is reduced, the fans, and above all the duct system,
can be designed with significantly smaller dimensions.
This reduces the cost and takes up less space.
This is where the induction thrust fan IHS is applied. It
is installed above the entry door and reduces thanks to
the generated air curtain the flow volume through the
opened entrance.
