One-of-a-kind, and fitted with integrated systems for dust reduction, MB`s range permit crushing operations to be carried out in enclosed spaces and areas with limited ventilation. Tunnel digs, underground systems and industrial warehouses are no longer a limit for on-site recycling. The efficiency of the entire MB`s range is constant both for indoor and outdoor use. A clear advantage, confirming the versatility of the range.
In some countries they do not allow tunnel atmosphere monitors to be mounted on the tunnel wall; also, where there is a single bore it is very difficult to gain access for maintenance purposes. The TunnelTech 400 series are extractive gaseous pollutant and visibility monitors and extract a gas and dust sample from the tunnel bore and carry to a remote analyser. This allows maintenance to take place without affecting tunnel traffic flow.
Tunnel ventilation systems are designed to enable a sufficient throughput of air to be maintained to ensure a safe operating environment for users. These systems consume large amounts of power and need to be operated as efficiently as possible. To do this it is necessary to know the effectiveness of the system in terms of air flow and direction developed within the tunnel. The TunnelTech 301 is a single point ultrasonic flow monitor that is unaffected by traffic flow and sound reflections. It is designed to...
CODEL`s road tunnel monitors are designed exclusively for road tunnel applications. It offers a family of tunnel sensors that provide all the essential measurements necessary to monitor the tunnel atmosphere.
According to the International Committee on Illumination CIE recommendations, luminance should be monitored as the luminance contained within in a conical field of view, subtending an angle of 20º. It is recommended that a luminance photometer is mounted in the tunnel approach road approximately 120 - 200 metres from the portal, depending on the approach speed of the vehicles and their stopping distance. The purpose of monitoring the luminance at the portal is to adjust the level of light intensity inside...
The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it is...
The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.
Modern intelligent traffic systems are designed to move traffic in an efficient manner as well as reduce the environmental impact of traffic on nearby populations. This includes the effects of noise, particle pollution and gases.
Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.
Conventional methods of firefighting have their limits when it comes to extinguishing fires in tunnels and underground railway shafts. The build-up of smoke and soot is an enormous hindrance to firefighting. Then there is the intense heat and the low concentration of oxygen because of the inertization process. In most cases the extinguisher jet cannot reach every part of the source of the fire.
