THE NEW CHILLER AND HEAT PUMP RANGE FOR THE GREENEST COMFORT
Hybrid falling film evaporator
By combining brilliant efficiencies and reduced refrigerant charge, the new hybrid falling film evaporator used in i-FX2-W-G04 is at the forefront of green innovation, fully developed and manufactured by MEHITS, it is characterized by:
- Top-level approach aligned with the best flooded technologies
- Very low pressure drops across all the range thanks to the optimized design
- Down to -50% refrigerant charge reduction compared to a traditional flooded evaporator
- Application flexibility thanks to its configurability
VSD Screw compressors
VSD screw compressors optimized for water source applications, with integrated frequency converter and Variable Vi technology.
2 independent refrigerant circuits on all sizes to ensure total reliability, very low continuous minimum capacity ratio and easy maintenance.
All-round Sustainability
Advanced technologies smartly combined with the green R1234ze HFO:
the perfect match for offering the highest efficiency levels.
Features
HFO 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 INDEPENDENT
2 completely independent 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 technological 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, these 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.
