High efficiency air cooled chiller with free-cooling
302 - 1693 kW

Outdoor unit for the production of chilled water, equipped with oil-free centrifugal compressors, R134a refrigerant, axial EC fans, condensing coil with copper tubes and aluminum fins, shell and tube flooded evaporator and electronic expansion valve. Base, supporting structure and panels are of galvanized epoxy powder coated steel. The unit is supplied with refrigerant and has been factory tested. On-site installation therefore just involves making connections to the mains power and water supplies. The rotor speed digital control allows an accurate and efficient thermoregulation in every operating condition. The economizer improves the refrigerant circuit efficiency (not present in sizes 0211 and 0452). These chillers, fitted with free-cooling coils, are used in IT-cooling, industrial and civil applications, when the cooling load is constant all-year-round or the outdoor air temperature is lower than the temperature of the liquid return line. In free cooling mode, the liquid is cooled by outdoor air, thus lowering the load of the compressors until it is reduced to zero. The NG configuration complies with applications where it is not allowed or desired the use of ethylene glycol.

Version

  • K - Key efficiency, compact version
  • CA - High energy efficiency units

Configurations

  • - - Basic function
  • NG - Function for free-cooling without use of glycole

Features

  • ENERGY SAVING
    Energy saving guaranteed by free-cooling, which exploits the low external air temperatures; free-cooling control with optional modulating valve.
  • VERY HIGH EFFICIENCY
    Top-level seasonal efficiency thanks to technlogical solutions at the forefront: magnetic levitation centrifugal compressors, flooded evaporator, EC fans and advanced control algorithms.
  • WIDE RANGE
    Extended capacity range.
  • LOW INRUSH CURRENTS
    Reduced breakaway starting currents thanks to the revolutionary centrifugal compressor.
  • EXTREMELY SILENT OPERATION
    Extremely silent operation in line with the best on the market, and highly reduced vibrations
  • INTEGRATED HYDRONIC GROUP
    It consists of 2 pumps with 4-pole motor, fixed or variable speed, with high or low head options to satisfy different industrial or IT-cooling applications and demands for comfort.

Accessory

  • Modulating valve for water temperature control in Free-Cooling mode
  • Hydronic group
  • VPF (Variable Primary Flow) kit: variable flow pumps with on board regulation
  • Fast restart
  • Double power supply with automatic changeover (ATS) or motorized changeover
  • Compressor power factor correction
  • Set-up for remote connectivity with ModBus/Echelon protocol cards
  • Touch Screen visual display
  • Remote control keyboard (distance to 200m and to 500m)

Controls

Electronic control W3000 TE
The brand new W3000TE controller offers advanced functions and algorithms. The large format keyboard and the wide LCD display favour an easy and safe access to the machine setup and a complete view of unit's staus. The assessment and intervention on the unit is managed through a multi-level menu, with selectable user’s language. The led icons immediately show the operating status of the circuits, as well as of the fans and of the water pumps (if present). An optional extra is the touch screen interface: 7.0” WVGA colour display with adjustable LED backlight and front USB port. The touch screen technology allows intuitive navigation between the various screens, safe access to the data with a three-level password protection as well as the graphic display of the performance of some monitored measurements. The diagnostics comprises a complete alarm management system, with “black box” (via PC) and alarm log functions (via display or also PC) for a better analysis of the unit performance. For the systems made of several units, the adjustment of the resources is performed by optional proprietary devices. Consumption metering and performance measurement are possible as well. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet-over-IP, Echelon LonWorks, Bacnet MS/TP protocols. Compatibility with the remote keyboard managing up to 8 units. The presence of the programmable timer allows the creation of an operating profile containing up to 4 typical days and 10 time bands. The control is characterized by the continuous modulation of the unit capacity, based on PID algorithms and referring to the water delivery temperature. Optionally (VPF package), capacity modulation can be integrated with hydraulic flow modulation, thanks to inverter-driven pumps and to specific resources for the hydraulic circuit.
