  • format_align_leftDescription
    Outdoor unit for the production of chilled water, equipped with semi-hermetic screw compressors, R134a refrigerant, axial-fans, condensing coil with copper tubes and aluminum fins, evaporative cooling system,shell and tube evaporator single pass and electronic expansion valve. Base, supporting structure and panels are of galvanized epoxy powder coated steel. The unit is supplied with anti-freeze oil and refrigerant and has been factory tested. These chillers, fitted with free-cooling coils and evaporative cooling system, are used when the cooling load is constant all-year-round. 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 evaporative cooling system is made of treated cellulose pads and a water circulator that keeps the pads wet. It lowers the air temperature before it reaches unit’s coils, thus increasing mechanical cooling efficiency and allowing free-cooling benefits to begin at higher outdoor temperatures. The NG configuration complies with applications where it is not allowed or desired the use of ethylene glycol.

    Versions

    • - - Basic
    • SL - Super-low noise version

    Configurations

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

    Features

    • EXTENSION OF FREE-COOLING TEMPERATURE RANGE
      Thanks to the evaporative cooling system that decreases the outdoor air temperature, the unit can take full advantage of the free-cooling benefit also in climatic conditions that normally don't permit it.
    • ENERGY SAVING
      Energy saving guaranteed by free-cooling, which exploits the low external air temperatures; free-cooling control with optional modulating valve.
    • WIDE RANGE
      Extended capacity range.
    • UNIQUE PROPOSAL - PATENT PENDING
      Booster function to increase chiller efficiency
    • INTEGRATED HYDRONIC GROUP
      The built-in hydronic group (optional) includes the main water circuit components. The 2 pumps are in twin configuration and available with 2 or 4-pole motor, fixed or variable speed, high or low head, to satisfy the different installation requirements.

    Accessories

    • EC fans with electronic DC brushless motor
    • 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

    Control

    • Electronic control W3000 TE
      W3000TE features a large keyboard and wide LCD display for an easy and safe access to the machine setup and a complete view of unit's status. The assessment and intervention on the unit is managed through a multi-level menu, with selectable user’s language. 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. Complete alarm management system is available, with the “black-box” and the alarm history display functions. 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 and supervision can be developed via proprietary devices or the integration in third party systems by means of the most common protocols ModBus, Bacnet, Bacnet-over-IP, LonWorks. Compatibility with remote keyboard (up to 8 units). The programmable timer allows the creation of an operating profile up to 4 typical days and 10 time bands. Continuous modulation of the unit capacity, based on PID algorithms and referring to the water delivery temperature.
