POMPE DE CALDURA, AER CONDITIONAT, CHILLER
FOCS2/K 1502 – 8404
Chiller, air source for outdoor installation
Cooling capacity 295 – 1818 kW
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 and thermostatic 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. This unit has been designed to optimize the costs – performances ratio.
K – Key efficiency, compact version
SL-K – Super Low noise, Key efficiency and compact version
D – Partial condensing heat recovery function
R – Total condensing heat recovery function
- THE BEST COMPROMISE PRICE – PERFORMANCE
This line has been conceived to optimize costs maintaining the units in class B or C as per Eurovent.
Flexibility in applications thanks to the many available functions and versions
Adaptability at the building’s cooling request thanks to the continuous capacity regulation, assured by sophisticated control’s logic.
- LEED RELEVANT PRODUCT
These units are compliant with the performance standard contained in the protocol of sustainability LEED
- WIDE OPERATING RANGE
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.
- Soft start
- NOISE REDUCER (only on no silenced versions)
- Compressor power factor correction
- VPF (Variable Primary Flow) kit: variable flow pumps with on board regulation
- Hydronic group
- Variable speed condensation control (standard on silenced versions)
- 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.
