Efficiency and power

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.

Replacement of gear box or belts by a permanent‐magnet motor reduces significantly maintenance costs and handling operations.

Besides, this new generation of motors coupled with their frequency converters guarantees a much higher efficiency compared with asynchronous motors (minimum 3 %).



Evaporative cooling remains the most ecological and economical technology: offering high-energy performance and competitiveness whilst respecting the Environment.

Totally dedicated to customers’ requirements and ahead of Legislation, Jacir has has perpetually improved its products to ease operation and maintenance equipment.

  • Improving thermal performances: Water flow, power, cold temperature
  • Adapting equipment to comply with new environmental standards:
