About COFINAIR by JACIR
With over 67 years of expertise, COFINAIR by JACIR has combined its know-how in aerodynamics, thermal engineering, and manufacturing materials to offer the market an exceptionally diverse range of water cooling solutions.
Our products, designed and manufactured in France, consistently anticipate environmental requirements by integrating noise constraints, various ventilation systems, and carefully selected materials and heat exchange components tailored to each industrial or tertiary application.
Most of the JACIR range is scalable and can later be equipped with plume abatement systems, as well as water- and energy-saving solutions and sound attenuation features.
- Open circuit cooling towers
- Closed circuit cooling towers
- Hybrid and low-noise cooling towers
- Adiabatic coolers
- Adiabatic condensers
COFINAIR by JACIR also supports each client with a full range of services dedicated to equipment monitoring and maintenance (refurbishment, spare parts, training, thermal diagnostics). A cooling tower rental service is also available, with installation carried out by experienced technicians in just one day.

Frequently Asked Questions
How does a cooling tower work?
The cooling tower works as a water-to-air heat exchanger in which the water mass is cooled by exchange with the ambient air.
In the case of cooling towers at open circuit, the direct encounter of air with process water allows a small amount of water to evaporate, and the remaining part to cool to a lower temperature, which will be recirculated in the industrial process.
In closed-circuit cooling towers, while still relying on the principle of evaporative cooling, process water remains inside a heat exchanger without coming into contact with ambient air, thus remaining free from possible contamination.
How to prevent Legionella in cooling towers?
By performing proper cleaning and maintenance of the cooling tower, the proliferation of bacteria, including Legionella, can be prevented. High water temperature inside the system and humidity can result in the proliferation of bacteria that are very dangerous to humans. Good maintenance and appropriate water treatment programs help preserve the cooling tower and keep it safe and efficient in performance.
Why is it important to use original replacement parts for cooling towers?
Choosing original components in cooling towers ensures the proper operation of the equipment over time, while ensuring the thermal performance provided at the design stage. Original spare parts make it possible to:
- Reduce the downtime of the cooling tower/evaporative condenser;
- Maintaining predetermined performance;
- Reliability and safety of equipment;
- Improved performance.
