Daikin Europe N.V. has introduced its EWAD~CZ air-cooled inverter chiller range, claimed to have the highest ESEER in the market – up to 6 (with optional fan speed regulation).
The use of inverter driven screw compressors in the EWAD~CZ range allows units to achieve the highest partial load efficiency levels in their class, making them ideal for systems with variable load requirements such as comfort applications. The high partial load efficiency of these solutions allows substantially reduced CO2emissions and decreased annual operating costs with attendant reductions in payback times.
Inverter technology also contributes to quieter sound levels and precise chiller water temperatures, as well as lower starting current requirements, optimum power factors (always above 0.95), a reduction of water tanks for the hydraulic system and increased reliability due to fewer compressor start-ups and shut-downs.
Inverter control is complemented by a host of other advanced features such as a patented single screw compressor, and ultra efficient fans with a patented blade profile for quiet operation. Furthermore, the new Microtech III controller allows easy control of performance parameters, and a wide range of system integration solutions are supported including LonWorks and BACnet.
Daikin EWAD~CZ chiller units can operate in ambient temperatures from -18 deg C to +50 deg C, with leaving water temperatures from -8 deg C to +15 deg C and are available in standard, low and reduced sound models. An extensive list of options includes heat recovery and fan speed regulation.
The addition of the new range makes the Daikin Europe screw inverter chiller portfolio the largest in the market, EWAD~CZ units filling in the top of the sector with capacities from 635 kW to 1.800 kW, the highest cooling capacity available in this market today.
