    Roof-Mounted Air Conditioner with Filter and Compact Controller

    Key Features

    • Compact design
    • High cooling capacity
    • Protection class: IP54
    • Resistant
    • Approval: CE

    Product Description

    häwa air conditioners can be us as independent devices up to an ambient temperature of max. 50/55 °C. They have two separate IP54-sealed air circuits, equipped with 1 fan each.

    Heat transfer from the inside of the cabinet to the outside takes place through active cooling (refrigerating unit).

    This allows to cool down the temperature in the cabinet below the ambient temperature. häwa air conditioners operate with the CFC-free, ozone-friendly refrigerant R134a.


    External fan operates only when cooling, which avoids unnecessary noise and pollution.

    The temperature is set at the factory to +35 °C. It can be field-adjusted from the outside at the controller display.

    A control line for the door switch, separately connected for units with a cooling capacity of 800 W or more, permits remote ON/OFF switching of the unit without power disconnect. General fault signal as potential-free changeover contact fed out in the control line.

    Free from silicone compounds, PCB, PCT, formaldehyde and cadmium.

    Standard controller KR-HS: Circuit board with one temperature gauge integrated in the device.

    Display controller KR-HD: Circuit board with 4 temperature gauges integrated in the device and control unit KR-B built into the front panel of the device. The internal fan is controlled via the door switch.

    The condensation is drained off directly via a discharge nozzle in the rear panel of the device.

    Power connection via a power cord fed through the air inlet.
