Air Conditioners with Filter and Thermostat Controller

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 after removal of the cover panel, or for devices equipped with a display, from the outside.

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.

Thermostat controller system: A capillary themostat controls the compressor and the external fan (for small air conditioners directly, for larger units via a contactor). The switching hysteresis is about 6 K.

For devices of 1000 W or more, the condensation is drained off directly via a discharge nozzle in the bottom panel.

Power connection via a power cord fed through the rear panel of the device.
