In the rare event that a burning ember is drawn into the fume extraction unit, there is the possibility that debris in the filters could ignite. Although any resultant fire would typically be retained within the fume extraction unit, this would cause significant damage and in extreme circumstances the risk may extend beyond the extraction unit. For processes where such risks have been identified, additional protection in the form of an in-line FireBOX is an additional precaution.
The built in temperature controller can be set so when a 10°C (18°F) temperature rise over the pre-set ambient temperature is detected, the FireBOX MA will activate the isolating valves and switch off the power to the extraction unit, suppressing the airflow to the FireBOX and reducing the fire. If this does not completely suppress the fire and the temperature rises another 10°C (18°F) then the fire extinguisher will be activated.
Independent tests by Ordnance Testing Solutions Ltd found the FireBOX MA is effective at containing and suppressing aluminium metal fires. It hosts all the same features and benefits as the FireBOX GA but has been designed specifically for metal-based applications. If you are not working with metal, please refer to the FireBOX GA or contact us to ensure you chose the right system.
