ABB has launched a new range of motors for smoke venting applications, designed to mitigate the development of fires in industrial and public buildings, tunnels and other locations.

ABB has launched a new range of motors for smoke venting applications, designed to mitigate the development of fires in industrial and public buildings, tunnels and other locations.

The motors have dual-purpose certification and can also be used for standard ventilation.

They are tested to withstand temperatures up to 400deg C for two hours.

ABB's smoke venting motors comply with the new European standard EN 12101-3, which will become mandatory in new installations from April 1, 2005.

Smoke venting motors are used in emergency ventilation to create smoke-free areas for rescue and fire fighting operations, as well as help reduce the spread of smoke and fire to other areas.

The new European standard determines the safety requirements to be fulfilled by motors intended for ventilation systems in closed or underground public spaces.

ABB's smoke venting motors range from 0.55 to 560 kW, IEC frame sizes 80 to 400.

Two-pole motors are available up to frame size 250 and 4-12 pole up to 400 frame size, single or two-speed, in aluminium or cast iron.

Pad mounting is available from size 280 and above.

Motors 160-400 frame size suitable for use on VSD supply (maximum rotational speed 1800rpm).

Maximum frequency on DOL or VSD equals 60HZ.
