Heating and Ventilation

Heating and Ventilation

Whether in the form of centrifugal, axial or propeller fans, ventilation is present throughout the commercial and industrial sectors. The main applications, such as heating, drying, air treatment and safety ventilation, need optimised drive mechanisms which are suitable for very specific environments.

Wide choice of solutions
To tackle the problems that arise in centrifugal, axial and propeller ventilation, Nidec Leroy-Somer offers a very wide range of drive mechanisms which meet the specific requirements of applications: safety motors certified for use in potentially explosive atmospheres or for smoke extraction, high-temperature motors, drive mechanisms, such as for example motors with a large number of poles, which make appliances significantly quieter, etc. In addition to two-speed motors, Nidec Leroy-Somer also offers variable speed solutions to maximise energy savings.

Expertise and reference projects
In partnership with its customers, Nidec Leroy-Somer optimises motorised fan torque and develops compact, energy-saving solutions. A ventilation laboratory determines the characteristics, in terms of air flow and acoustics, of motorised fans with flow rates of up to 30,000 m3 per hour.

Our international references in this business are testament to our customers' satisfaction: metro systems in Istanbul, Algiers and Cairo, the Dubai hippodrome, the Stade de France, the Tour de la Défense, Athens Airport, etc.
