Faced with the many energy challenges but also the new regulations, the engineers of the group CETAB, responsible for the structure Design and amenities, control climate engineering and all fluids associated
This department uses several skills, from studying to innovation: HVAC, special fluids medical and industrial, plumbing, Fire Safety, smoke extraction, sprinklers, Fire hose cabinet…
We design complex installations with thermal comfort, air handling, depollution clean rooms, but also installations dedicated to renewable energy (Geothermal energy, solar energy, biomass boiler, heating network, CHP, wind power plants, heat pump with a ground coupled heat exchanger).
