i-FX2-W-G04 0402 - 1242
Indoor unit for the production of chilled water, with high efficiency variable speed (Inverter Driven) screw compressors optimized for low compression ratios and specifically designed for near zero GWP HFO R1234ze refrigerant. All the sizes are designed with two completely indipendent refrigerant circuits, electronic expansion valves, high performing shell and tube condenser and shell and tube hybrid (flooded/falling film) evaporator with low refrigerant charge technology and high heat transfer coefficiecents, both designed and manufactured by Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A. These advanced solutions allows the unit to achieve high efficiencies with low refrigerant charge.

Product features
Features
LOW GWP REFRIGERANT
4th generation refrigerant HFO 1234ze, with negligible greenhouse effect in comparison with traditional HFC refrigerants (Global Warming Potential GWP of HFO 1234ze < 1, GWP of R134a = 1300 as per IPCC rev. 5th) and zero impact on the ozone layer.
HYBRID FLOODED/FALLING FILM HEAT EXCHANGER
The hybrid flooded/falling film evaporator, designed and manufactured by Mitsubishi Electric Hydronics and TI Cooling Systems, enables low refrigerant charge and high heat transfer coefficients.
2 REFRIGERANT CIRCUITS COMPLETELY INDIPENDENT
2 completely indipendent refrigerant circuits each equipped with a VSD screw compressor to ensure a perfect balance of the cooling capacity produced
WIDE OPERATING RANGE
VSD compressors and kit HWT allow unit to reach condenser high temperature. Standard unit can produce hot water up to 52°C while exploiting HWT kit it is possible to reach condenser water temperature up to 72°C.
SILENT OPERATION
Extremely silent operation thanks to the unit's accurate design. Optional integral acoustic enclosure, further reduces the sound level beyond the best on market
HIGH EFFICIENCY AT PARTIAL LOAD
Top-level partial load efficiency thanks to technlogical solutions at the forefront: VSD screw compressors, hybrid flooded/falling film evaporator and advanced control algorithms.
GROUP CONTROLS WITH DYNAMIC MASTER
Load sharing, sequencing, active redundancy, priority of resource activation, alarm management, theese are only some of the LAN functions that the unit is able to manage when connected to a group of chillers. Besides, the system's stability is ensured even in case of alarm or malfunctioning thanks to the Dynamic Master logic.
VARIABLE PRIMARY FLOW
Energy savings due to variable pump speed management based on load demand and the variable flow ensures the units also function in critical working conditions.

Electronic control W3000+
W3000+ features an easy-to-use interface and a complete LCD display that allows one to consult and intervene by means of a multi-language menu (19 languages are available). The diagnostics includes a complete alarm management, with the “black-box” and the alarm history display for enhanced analysis of the unit operation. The programmable timer manages a weekly schedule organized into time bands to optimize unit performance by minimizing power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points. As option, KIPlink is available - Keyboard In Your Pocket. KIPlink is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the smartphone or tablet.
The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimize performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available.
Optional proprietary devices can perform the adjustment of 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-over-IP, Bacnet MS/TP RS485, Konnex, ModBus TCP/IP, SNMP. Compatibility with the remote keyboard (up to 8 units).
