For safer indoor air quality. HVAC equipment is part of an overall approach to helping maintain indoor air quality standards and protect against the spread of diseases.
Indoor air quality has now become a key challenge for building owners and managers. Our indoor environment must be preserved, protected, and made reliable. Together, we share the same ambition, helping to support the health and well-being of others. We call our approach #CIAT4life.

#CIAT4life : 4 foundational pillars



At the centre of our relationship, to guarantee that your result is optimal and lasting.


Expert solutions that meet the demands specific to your sites.


Providing effective help at each stage, whatever your project.


Reliable and efficient technology and commissioning that have repeatedly proven themselves.

IAQ experts

To ensure you are provided with the right solutions, CIAT experts will work alongside you from conception and throughout the implementation of your project.

They will analyse your specifications, and thanks to their expertise and specific software designed by our engineers, they will provide you with the optimum solution to meet your requirements.
