POMPE DE CALDURA, AER CONDITIONAT, CHILLER
TECS2 HFO 0351 – 1053
High efficiency chiller, air source for outdoor installation
Cooling capacity 339 – 1017 kW
Outdoor unit for the production of chilled water featuring oil-free centrifugal compressor, with refrigerant HFO (1234-ze), axial-flow fans, condensing coil with copper tubes and aluminium fins, shell and tube flooded evaporator and electronic regulation 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 together with the use of inverter technology. The compressor is radically innovative: magnetic bearings and digital rotor speed control allow partial load efficiency levels to be reached that were hither to impossible.
SL-CA-E – Super Low noise version, Premium efficiency, Class A enhanced (based on Eurovent classification)
- HFO REFRIGERANT
4th generation refrigerant HFO 1234ze, with zero impact on the ozone layer and negligible greenhouse effect in comparison with traditional HFC refrigerants (Global Warming Potential GWP of HFO 1234ze =7, GWP of R134a =1430).
- VERY HIGH EFFICIENCY
Very high efficiency at full and partial load, to top market levels, thanks to adopted technological solutions: large capacity modulation and expanded exchanger, offering minimum running costs of the unit in real working conditions.
- EXTREMELY SILENT OPERATION
The best compromise between silence and efficiency, as result of a sistematic design oriented to minimize the noise level.
- LOW INRUSH CURRENTS
Reduced breakaway starting currents thanks to the revolutionary centrifugal compressor.
- VPF (Variable Primary Flow) kit: variable flow pumps with on board regulation
- Hydronic group
- Set-up for remote connectivity with ModBus/Echelon protocol cards
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.
