  • General characteristics

    k.Air is the ready-to-use solution for managing air handling and ventilation units.

    k.Air is a preprogrammed and fully-configurable controller, designed to reduce times and costs, from design right through to commissioning. It offers considerable flexibility, so as manage as many applications as possible, from the simplest to the most complex unit.

    The distinctive feature of k.Air is the result of CAREL's extensive experience in air handling unit and humidification management applications. Its intelligent control logic in fact ensures comfort, indoor air quality and a healthy environment, always with the lowest energy consumption, through hygienic and efficient operation of all of the components of the air handling unit.

    k.Air offers an advanced user experience: simplified access to information for users and service via an integrated web interface. A set of graphic pages with unit dashboards are available from first start-up, ready to be used with the new pGDx family of touchscreen displays.
