DX-A series air-cooled heat pump chillers are widely used in newly built and rebuilt large and small industrial and civil building air-conditioning projects, such as hotels, apartments, hotels, office buildings, shopping malls, theaters, factories, hospitals, etc. Especially for projects that have high requirements on noise and surrounding environment, and it is inconvenient to install boilers and cooling towers or cooling water pumps, it is an ideal choice.
Adopt Taiwan Hanbell/German Bitzer screw compressor, or Japan Daikin scroll compressor;
heat exchanger adopts imported high-efficiency heat exchanger;
automatic temperature control is intelligent; the
most reliable unit protection;
users only need to configure external Connect the pipeline to the unit and connect the electrical silk circuit to put it into use.
