Residential chillers and heat pumps

Climaveneta > Commercial and industrial chillers

FOCS2/CA 1502 – 6603

High efficiency chiller, air source for outdoor installation
Cooling capacity 307 – 1543 kW

NECS 0202T - 0612T
Outdoor unit for the production of chilled water with semi-hermetic screw compressors optimized for R134a, axial-flow fans, condensing coil with copper tubes and aluminium fins, single step shell and tubes evaporator designed by Climaveneta and electronic expansion valve. Base and supporting structure and panels are of galvanized epoxy powder coated steel with increased thickness. Flexible and reliable unit; it easily adapts itself to different thermal load conditions thanks to the precise thermoregulation. The high performance’s level is achieved thanks to the accurate sizing of all internal components.


CA – Class A of efficiency
SL-CA – Super Low noise version, Class A of efficiency
CA-E – Premium efficiency version: Class A enhanced
SL-CA-E – Super Low noise version, Premium efficiency, Class A enhanced



Basic function
D – Partial condensing heat recovery function
R – Total condensing heat recovery function


    Unit in Class A as per Eurovent. High efficiency for low energy consumption during the operating hours
    The version ´CA-E´ is characterized by efficiency beyond the ´Class A´ for Eurovent. The technological choices adopted assure the minimization of operating costs and therefore a quick payback time.
    As the result of a systematic design oriented to minimize the noise level, the silenced version units give the best combination of quietness and efficiency on the market.
    Flexibility in the applications thanks to the many configurations and versions available.
    These units are compliant with the performance standard contained in the protocol of sustainability LEED
    Extensive range of operation with external air temperature up to 46°C at full load; with total heat recovery, hot water can be produced up to a temperature of 55°C


  • Hydronic group
  • VPF (Variable Primary Flow) kit: variable flow pumps with on board regulation
  • NOISE REDUCER (only on no silenced versions)
  • Compressor power factor correction
  • Soft start
  • EC fans with electronic DC brushless motor
  • Compressor enclosure (standard on silenced versions)
  • KIT HT to increase the unit operating conditions range
  • Set-up for remote connectivity with ModBus/Echelon protocol cards
  • Remote control keyboard (distance to 200m and to 500m)


  • W3000SE Large
    The W3000 SE Large controller offers advanced functions and algorithms. The keypad is generously sized with full operating status display. The commands and detailed LCD display make access to the unit’s settings easy and safe. These resources allow to consult and intervene on the unit by means of a multi-level menu, with selectable language setting. It´s available as option the touch screen interface: WVGA 7´´ colour display with LED adjustable back lighting. The touch screen technology allows an intuitive navigation, ensure a safety data access through 3 different password levels and permits to visualize in diagrams some monitored quantities trend. The diagnostics includes a complete alarm management, with the „black-box” and alarm logging functions for enhanced analysis of the unit operation. For multiple units’ systems, the regulation of the resources, via optional proprietary devices, can be implemented. Energy metering, for both consumption and capacity, can also be developed. 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, Bacnet-over-IP, Echelon LonWorks. Compatibility with the remote keyboard managing up to 10 units. Availability of an internal real time clock for operation scheduling (4-day profiles with 10 hour belts). The regulation features the continuous modulation of capacity, based on a dynamic dead band and referring to the leaving water temperature. As alternative, step-wise regulation is also available, referred to the return water temperature with selectable proportional- or proportional-integral logic. As option (VPF package), the modulation of capacity is integrated with the modulation of the water flow, by means of inverter and dedicated resources for the hydraulic circuit.
