Claims Mosen’s tunnel jet ventilation system cuts installation costs and increases energy efficiency

Systemair has announced signing an exclusive licensing agreement for the production and marketing of a new type of tunnel ventilation system, developed by Dr Fathi Tarada, Managing Director of Mosen. The innovative ventilation system was developed in order to reduce the space requirements for fans and, thus, increase energy efficiency and reduce the number of required fans in tunnels, the announcement said.

According to Systemair, The set objectives have been achieved through the development of the MoJet, for which UK and International PCT (Patent Cooperation Treat) patent applications have already been filed. The innovation permits the aerodynamic thrust to be significantly enhanced, while simultaneously reducing power requirements, the announcement claimed.

In this context, Dr Fathi said that it was possible to increase the thrust by up to 20%, and depending upon the installation, the efficiency could be improved by up to 40%. He believed that a particular advantage was the reduced installation height, which could be reduced by up to 15%. This minimised place requirements while avoiding encroachment into the traffic space. This could be achieved with a smaller diameter and reduced fan weight of up to 20% than conventional jet fans, while still delivering the same thrust, Dr Fathi emphasised. The innovation would allow the fans to be installed closer to the tunnel walls and soffit and permitted lower installation and cabling costs (through reduced longitudinal distances between fans), the announcement said.
