Climascience accompanies its customers beyond the commissioning of their systems. Over the years and projects, we have developed expertise and strong experience in preventive maintenance and MOC (maintenance in operational condition). We take great care in the recruitment of our technicians and their training in complex and critical systems.

Thirty people, who are specialised in sensitive sites, work in our Maintenance Department. Our teams provide preventive maintenance on air handling systems. They also provide multi-technical maintenance for sites requiring a high level of technicality: research sites, military sites, industrial sites, university sites, etc.

Climascience has also developed its in-house capabilities to provide Maintenance in Operational Condition (MOC) of its customers’ systems exposed to health risks in the event of a failure of systems and engineers specialising in risk management and industrial safety have joined Climascience’s teams.
