ABB Smoke Spill Motor

Overview

Smoke extraction motors play a critical role in keeping tunnels safe. In the event of a tunnel fire, lives depend on the ability of extraction fans – and the electric motors driving them – to disperse toxic fumes and smoke quickly and efficiently. Smoke extraction motors must be capable of withstanding the high temperatures generated in fire zones and continue to work reliably under these extreme circumstances. In normal daily operation, they are part of the comfort ventilation system, which maintains tunnel air quality. Ideally, the motors are controlled by variable speed drives (VSDs) to allow adjustable fan settings, saving energy.

Features

Smoke extraction motors are typically used in two types of applications – jet fans and axial fans – for both comfort ventilation and extreme cases during fires.
