Water-cooled chillers
Water cooled chiller 124-401 kW
FX-W 0551 - 1752

Indoor unit for the production of chilled water featuring semihermetic screw compressors optimized to operate with low compression ratio and R134a, shell and tubes evaporator designed by Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A. and shell and tube condenser and electronic expansion valve.

Base and supporting structure is made of polyester painted galvanized steel. Eurovent certification. The unit results extremely compact, thanks to the peculiar construction layout, without base frame and panels, and extremely flexible to 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.


Electronic control W3000TE
The brand new W3000TE controller offers advanced functions and algorithms. The LARGE keyboard with a large format and the wide LCD display favour an easy and safe access to the machine setup and a complete view of unit's status. 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. In addition to or as an alternative at Large Keyboard, the KIPlink - Keyboard In Your Pocket - is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the smartphone or tablet.

The diagnostics comprises a complete alarm management system, with “black box” (via PC) and alarm log functions (via display or also PC) for enhanced analysis of the unit operation.

Optional proprietary devices can perform the adjustment of the resources in systems made of several units. 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, Bacnet-over-IP, LonWorks.

Compatibility with the remote keyboard managing up to 8 units. The programmable timer manages a weekly schedule organised into time bands to optimise unit performance by minimising power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points. The regulation operates on the water circuits featuring the step-wise regulation referred to the return water temperature with proportional logic. 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.

Thanks to the high level of efficiency at part load, the unit can meet and exceed the minimum energy efficiency threshold rated by the Seasonal Energy Efficiency Ratio SEER, in accordance with the eco-sustainable design requirements for all products using energy. For this reason, the unit represents the best choice for all the hydronic installations on the residential and commercial air conditioning systems.


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


The electronic expansion valve brings several benefits especially in case of variable thermal load conditions and source temperature. It improves the efficiency of the unit and reduces power consumption, and allows a faster ramp-up time and wider operating limits.


Adaptability at the building’s cooling request thanks to the continuous capacity regulation, assured by sophisticated control’s logic.
