The CWW/CCY 4031÷11682 units, with R134a refrigerant and innovative technology, are the technologic and innovative heart of the most selective air conditioning and refrigeration systems. These units, provided with touch screen interface and featuring A CLASS energy efficiency, are designed especially for large size systems, intensively used throughout the year. The units, equipped with Inverter technology (optional), combined with the use of last generation Centrifugal compressors, reach outstanding EER and IPLV energy
coefficients: respectively up to 6,2 at full load and up to 10 at partial load. The extremely high reliability of the series is achieved through the careful control of power, even at partial loads, which minimizes the number of stops and starts and extends the useful life of the compressor. The solidity of the mechanical parts and the wide range of solutions in terms of accessories and system arrangements make the unit sturdy, but at the same time flexible, suitable for any type of application. In addition, the units are equipped with a WEB MONITORING system, for the monitoring and remote management of the units through the communication protocol GPRS/EDGE/3G/TCP-IP. Users enabled to the use of this service can, by using a specific webpage, have access to the Monitoring, Managing and Statistics activities.
