WCT

SPECS OVERVIEW

• Cooling capacity range: 7750 kW to 11400 kW
• Counterflow centrifugal chillers with two stage compressor
• Two efficiency packages - Standard and Premium (0.648kW/ton and 0.616 kW/ton respectively)
• R-134a refrigerant

BENEFITS

• Chiller series counterflow arrangement provides the full load efficiency advantage of two separate chillers arranged for counter flow operation in a single compact unit. Also enabling each compressor to operate at lower head to increase the energy performance at full load
• Daikin precision engineered gear driven design allows for lighter components, less vibration and ability to select gear ratio to provide optimum impeller speed based on building demand
• *Evaporator water: 13.3/4.5°C – Condenser water: 35/40.5°C
• Ensuring the lowest total cost of ownership in district cooling or large size cooling plants applications
• The controls are pre-wired, adjusted and tested
• Positive Pressure Design

FEATURES

• 2 circuits arranged in series – counter flow (for each unit of the package)
• Unique innovative 'back-to-back' impeller design resulting in reduction of 67% trust load and improved reliability and bearing life
• Unique diffuser control to avoid surging resulting in 10% efficiency increase at part load versus hot gas bypass
• Flooded & shell tubes evaporator and condenser, including two separate refrigerant circuits
• BAS communication capability via LONMARK, Modbus or BACnet standard protocols for BAS manufacturers
• Low noise and vibration with Daikin gear drive technology
• Built-in redundancy with two of everything connected to the evaporator and condenser (2x drive lines, lubrication and control systems, expansion vales and economiser)
• Packaged solution, bolt-together construction on single and dual compressor chillers
• Optional factory disassembly to overcome site access restrictions
