Copeland
The ZXD range of Digital modulated medium temperature units benefit from patented Digital scroll technology. This allows a simple and very reliable variable capacity system. The digital modulated variable capacity ZXD medium temperature unit comes with Copeland Climate Technologies proven EC2-552 controller. The EC2 controller provides real time load estimation and controls the delivered capacity by changing the digital modulation rate. The controller also provides the basic protection including the high discharge temperature trip. The controller also displays the suction pressure, saturated evaporating temperature based on the suction pressure, modulation rate and discharge line temperature.
