MoJet®
Cut Costs & Reduce Energy Consumption for Tunnel Ventilation
Mosen Ltd has patented the unique MoJet® tunnel ventilation system, which has been adopted in a number of metro and road tunnels worldwide. This device can enhance the aerodynamic thrust delivered by jetfans by 20% to 60%. It does this by using convergent nozzles to accelerate the flow and turn it away from the tunnel soffit and walls, thus reducing friction between the jet and the tunnel surfaces. The reduction in aerodynamic friction leads to significantly improved energy efficiency, as well as fewer jetfans being required to provide tunnel ventilation.
Cabling costs can be reduced, since the MoJets® can be installed at the portals and arranged at a much closer longitudinal distance from each other. Smaller diameter fans can be selected for the same installed thrust as conventional jetfans (with about 20% less weight and 15% less installation height). MoJets® do not encroach upon the traffic envelope, and can be installed very close to tunnel walls and soffits, hence reducing space requirements.
