PERMANENT MAGNET MOTORS: SAFE INSTALLATION, POWER CONSUMPTION AND MAINTENANCE COSTS REDUCTION

- Better power performance
- No more fan coupling and maintenance on cooling towers

The coupling system of motor to fan (belts and gear box) requires a drastic care for the good cooling of a process, particularly if they are located in the wet airflow.

The elimination of these critical parts decreases costs and maintenance operations while securing the reliability of the equipment.

Besides, this new generation of motors coupled with their frequency converters guarantees a much higher efficiency compared with asynchronous motors.

PLUME SUPPRESSION AND SOUND ATTENUATION

Plume : the plume is the condensation result of water vapour contained inside saturated air at the outlet of the cooling tower when mixing with outside colder temperature.

The plume is generally more visible during cold or wet ambient conditions. Plume suppression is realised by adding a finned tube coil at the outlet of the cooling tower to heat this wet saturated air, and to move it away from its saturation point and avoid water vapour condensation return at the atmosphere.


COOLING TOWER'S SOUNDPROOFING

Replacement or adaptation of sound attenuation casing on a centrifugal or axial fan :


For induced draft type, the sound level of a cooling tower already installed can be lowed thanks to sound attenuation casing placed at the top of the unit.

In case of blower fan (on the side) , sound attenuation is realised by a motor-fan group fan housing.

EFFI-SILENT Noise abatement specially designed for Cooling Towers basins : noise reduction from 3 to 4dBA according cooling tower type .
