The DEA Series is an air conditioning device that integrates with traditional radiant systems. Thanks to discreet and unobtrusive ventilation, it is able to quickly restore the desired level of climatic comfort to the rooms, especially in the summer season and in those rooms that connect the inside to the outside. When the thermo-hygrometric parameters in the room diverge from those demanded, the system is automatically activated to integrate with the radiant system and once the optimal conditions have been restored, the DEA Series limits itself to controlling the humidity, leaving the radiant system the task of maintaining the internal temperature. In this way, the inhabitants can use the building without being limited by the system, and are totally free to use all the rooms without having to compromise on the level of wellbeing.
