Medium Temperature Variable Capacity
Emerson Climate Technologies’ digital modulated variable capacity Copeland Scroll™ ZXD MT condensing unit is equipped with the 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 basic protection including high discharge temperature trip. The EC2 controller displays the suction pressure, saturated evaporating temperature based on the suction pressure, modulation rate and discharge line temperature. It has a manual and web-enabled interface for the initial set up of initial parameters.
 
Copeland Scroll ZXD range of digital modulated MT condensing units benefit from the patented digital scroll technology that allows a simple and reliable variable capacity system at MT envelope.
