TX-W 1A00 - 6D00

High efficiency water cooled chiller 246 - 4549 kW

Indoor unit for the production of chilled water featuring centrifugal oil-free compressors, with R134a, electronic regulation valve, shell and tube condenser and shell and tube flooded evaporator. Base and supporting structure and panels are made 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.

Features

NO COMPROMISE

Variety of compressor combinations (up to 6 compressors on the same unit), plus the flexibility to choose the heat exchangers that can satisfy each specific installation and design requirements: the highest full load efficiency, the best initial investment, an unrivaled seasonal efficiency, an operating range suitable for applications in systems operating at high or low condensation (dry coolers or cooling towers).

VERY HIGH EFFICIENCY

Very high efficiency at full and partial loads, at top market levels, thanks to the technological solutions adopted: large capacity modulation and expanded exchanger, offering minimal running costs of the unit in real working conditions.

FLEXIBLE COMPOSITION

Choice between horizontal or diagonal arrangement of the heat exchangers, with dimensions that favor the compact overall dimensions in height or footprint, water connections to the evaporator and condenser that can be deployed on the right or left, to fit any application.

ADAPTABILITY

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

LOW INRUSH CURRENTS

Reduced breakaway starting currents thanks to the revolutionary centrifugal compressor.

EXTREMELY SILENT OPERATION

Extremely silent operation in line with the best on the market, and highly reduced vibrations

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.
