FOCS3-W-G05 0551 - 4752

Water cooled chiller 188 - 1693 kW

Indoor unit for the production of chilled water featuring semihermetic screw compressors optimized to operate with low compression ratio and R513A, electronic expansion valve, shell and tube condenser and shell and tube flooded evaporator. The unit results extremely compact, thanks to the peculiar construction layout, without base, frame, and panels. At the same time high efficiency is guaranteed by the innovative optimized compressors and high performing heat exchangers.

Features

HIGH EFFICIENCY

Very high efficiency at full and partial loads, at the highest market levels, thanks to the adopted technological solutions. These units ensure low operating costs and therefore a quick payback time.

ADAPTABILITY

Can adapt to the building’s cooling request thanks to the continuous capacity regulation, assured by the control's sophisticated logic.

MAXIMUM COMPACTNESS

Maximum compactness offers very high flexibility in the design process and installation operations, offering a premium solution in case of reduced clearances or when retrofitting existing installations.

AHRI CERTIFICATION

Certified in accordance with the AHRI Water-Cooled Water-Chilling and Heat Pump Water-Heating Packages Certification Program, which is based on AHRI Standard 550/590 (I-P). Certified units may be found in the AHRI Directory at www.ahridirectory.org

W3000TE

The W3000TE controller offers advanced functions and algorithms. The large format keyboard provides a complete overview of the unit's status. The controls and the complete LCD display favor an easy and safe access to the unit's setup. These resources provide assessment and intervention of the unit, by means of a multi-level menu, with multiple languages available. The LED icons immediately show the circuit's operating status, as well as the fans and the water pumps (if present). The touch screen interface: 7.0” WVGA color display with adjustable LED back-light and front USB port is available as an option. 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 are comprised of 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's performance. For the systems made up 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 to manage up to 8 units. The presence of the programmable timer allows for 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.
