The new DWDC C series is the next generation water cooled chiller incorporates brand new features in a unique design for every component manufactured by Daikin.
This product relaunches the consolidated fame of the Daikin centrifugal chiller series in a brand new design specifically developed to satisfy the European and Middle East markets.
Available in a wide choice of cooling capacities and component combinations, the range has been developed to optimize energy efficiency and reduce operating costs. Maximizing performance at both full- and part-loads, the new Dual compressor chillers are available with R-134a or R-513A or R-1234ze, in single refrigerant circuit design.
As part of a building system, centrifugal compressor chillers represent a significant investment. Suitable for new build or retrofit, the new chiller range delivers real benefits for the bottom line.
The dual compressor DWDC C chillers offer many benefits, including outstanding part-load efficiency, and system redundancy similar to two separate chillers, with a lower total installed cost. The DWDC C can be equipped with Variable Speed Drive, for which Daikin has introduced a brand new and enhanced solution with this latest product series.
Daikin DWDC C dual centrifugal compressor chiller range offers a choice of cooling capacity from 2100kW (600RT) up to 9000kW (2500RT) with both R-134a and R-513A & cooling capacity from 1500kW (450RT) up to 6700kW (1900RT) with R-1234ze at nominal AHRI conditions.
All models are fitted with a single refrigerant circuit.
‘Right-sizing’ chiller selection offers reduced installation costs from the outset: DWDC C series allows virtually infinite combinations of heat exchangers, gears, and semi-hermetic motors to provide the exact required capacity, minimizing the need for a costly step up to a larger-size chiller package.
The Redundancy Feature
Daikin DWDC C dual centrifugal compressor chillers have two of everything connected to the evaporator and condenser – two compressors, two lubrication systems, two control systems, and two starters.If any component on a compressor system fails, the component can be removed or repaired without shutting down the other compressor; providing an automatic back-up with at least 60 percent of the chiller design capacity available on DWDC units.
Redundancy is also built into the distributed control system, which consists of a unit controller, a compressor controller for each compressor and an operator interface touch screen. The chiller will operate normally without the touch screen being functional. If a compressor controller is unavailable, the other compressor will operate normally and handle as much of the load as possible.
