  • format_align_leftDescription
    Outdoor unit for the production of high temperature chilled water equipped with scroll compressors, R410A refrigerant, axial-fans, micro-channel full-aluminum condensing coils, shell and tube evaporator, and electronic expansion valves. Base, supporting structure, and panels are of galvanized epoxy powder coated steel. The free-cooling system chills the water exploiting the outdoor air cold temperatures. It consists of additional water coils, made of copper tubes and aluminum fins, and a devoted hydraulic valve system. The NG configuration complies with applications where it is not allowed or desired the use of ethylene glycol.

    Versions

    • K - Standard efficiency
    • SL-K - Super low noise, standard efficiency
    • A - High efficiency
    • SL-A - Super low noise, high efficiency

    Configurations

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

    Features

    • HIGH TEMPERATURE OF CHILLED WATER
      Designed for the production of chilled water with high temperature and high delta T, this unit is the ideal solution for the modern IT-cooling systems, where this optimization allows great energy savings.
    • FREE-COOLING
      The generous size of the free-cooling coils allows to produce the nominal cooling capacity without the use of the compressors for many hours per year, thus cutting the annual energy consuption.
    • GROUP CONTROLS WITH DYNAMIC MASTER
      Load sharing, sequencing, active redundancy, priority of resource activation, alarm management, theese are only some of the LAN functions that the unit is able to manage when connected to a group of chillers. Besides, the system's stability is ensured even in case of alarm or malfunctioning thanks to the Dynamic Master logic.
    • ADAPTIVE SET-POINT
      This function connects the indoor units (close control) with the external group of chillers. An advanced algorithm instantaneously detects the actual indoor thermal load and conveys this information to the chillers, thus optimizing the operation of the whole system.
    • INTEGRATED HYDRONIC GROUP
      The optional built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line, for achieving both low or high head.
    • VARIABLE PRIMARY FLOW
      Energy saving due to variable pump speed management based on load demand and the variable flow assures the functioning of the units also with critical working conditions.

    Control

    • Electronic control W3000+
      The W3000+ controller offers proprietary functions and algorithms. The thermoregulation features the capacity modulation based on PID algorithms with dynamic neutral zone related to the leaving water temperature. Diagnostics include complete alarm management, with “blackbox” functions (via PC) and alarm log (display or PC). W3000+ includes group regulation logics (LAN) with Dynamic master management, developed to maximize energy efficiency and reliability in multi-unit systems. Supervision is possible using proprietary devices or third-party systems through the most common communication protocols. Compatibility with the remote keyboard (up to 8 units). Consumption metering and performance measurement are possible as well. KIPlink - Keyboard In Your Pocket - is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the smartphone or tablet. Using KIPlink, it is possible to turn the unit on and off, adjust the set-point, plot the main operating variables, monitor in detail the status of the refrigerant circuits and the main components, and display and reset the possible alarms. In addition to or as an alternative, the Touch interface, with a 7” WVGA colour display and a front USB port, or the Large keyboard, with a wide LCD display and led icons, are available.
