Tyre recycling in Qatar

Rubber consumption has been seen climbing as tire demand grows. According to a report from Southeast Asian research for LMC International, global rubber consumption will grow an average of 3.5 percent a year through 2018 as demand increases for replacement tires, supporting prices of the commodity.

  • MRT

    Metro and Rail Ventilation

    Underground transport and rail systems become more and more frequent as they allow rapid transit times while transporting a large number of users. The network of high speed trains and also standard rails are more and more transferred to underground tunnels in order to mitigate the environmental impact.

    Both applications need ventilation rates. In Metros the influx of a large number of people and the presence of moving trains generate a reduction of oxygen and an increase in heat and pollutant. Mechanical ventilation is then required to achieve the necessary air exchange and grant users of the underground train systems comfortable conditions.

    Ventilation systems have a second and even more important purpose. That is to guarantee safety in case of fire emergency. In order to create a safe and clean environment for escaping mechanical ventilation both in tunnels and in the stations is activated. In rails the ventilation of tunnels is mainly dedicated to fire emergencies where it is vital to keep under control the smoke propagation and create safe areas and clear environment for the users.

  • Drilling

    Tunnel Drilling Ventilation

    Ventilation during tunnel construction is needed so to provide the external air required to dilute the pollutants produced by the machines used during the different stages of the manufacturing. The working squads a safe environment.

    Our wide product range ensures you the most suitable solution for ventilation in the construction phase of the tunnel. We can size the systems in accordance with the enforced laws. The product range consists of axial fans single or multi staging to achieve the required system pressure for any tunnel length. High-tensile ventilation ducts, efficient inverters and reliable dedusters complement our system.

  • Road Tunnel

    Road Tunnel Ventilation

    In road tunnels ventilation rates are needed to dilute the pollutant emissions from vehicles - like Carbon Monoxide (CO), Nitrogen Oxides (NOx) and soot (particles matter) - in order to keep acceptable air quality for the users.

    Just as important is controlling the effects of a fire in tunnels. The ventilation system needs to be designed and sized to provide sufficient velocity and direction for controlling the spread of smoke and heat in the event of fire.

    The ventilation systems can be configured depending on different key elements such as: length, traffic direction, gradient, flow rates, fire size and scenario etc.

    Systemair provides technical expertise for the design of the ventilation systems, supplies state of the art products and gives support for the installation, commissioning and operation of the delivered systems.
