Profile: PSB-UK Ltd. is a supplier of ventilation systems. We design, manufacture and install smoke control systems for tunnels, commercial and industrial buildings. We develop fire detection and smoke control systems. We also offer technical advice on the optimum positioning of ventilation systems. We specialize in developing impulse ventilation systems for above ground and below ground applications. Our products include the axial type of impulse fan and the centrifugal type of induction fan. These two fans influence the direction of airflow within the environment to ensure that all areas are efficiently ventilated. They also induce air turbulence during daily ventilation to ensure efficient mixing and dilution of pollutant gases with fresh air. They are also designed to manage the flow of hot smoky gases in the event of fire.
