Mosen teams up with Systemair to develop tunnel jet ventilation system

Fire engineering firm Mosen signed an agreement with German manufacturer Systemair last week to produce its new tunnel jet ventilation system called Mojet which reduces the number of fans required in a tunnel.

Systemair’s specialist subsidiary for fans and ventilation technology based in Windischbuch, Germany has signed an exclusive licensing agreement for the production and marketing of a new type of tunnel ventilation system.

Mosen managing director Fathi Tarada developed the technology, MoJet, to meet the objectives of reducing the space requirements for fans, to increase energy efficiency and to reduce the number of required fans in tunnels.

“It is possible to increase the thrust by up to 20%, and depending upon the installation, the efficiency can be improved by up to 40%”, said Tarada.

The new system uses jet fans with a smaller diameter and reduced fan weight of up to 20% compared to traditional jet fans whilst still delivering the same thrust. This reduction allows fans to be installed closer to the tunnel walls and reduces possible encroachment into the traffic space.

“This licence agreement represents a further step for Systemair into the future, since it will enable us to win additional market share in the area of tunnel ventilation and to differentiate its products from those offered by the competition,” said Systemair managing director Kurt Maurer.
