QUATTRO EA

QUATTRO R454B is a multifunctional air-water units with axial fans and hermetic scroll compressor for associated systems with 4 pipes.‎ The four-pipe technology is considered the best energy efficient solution able to satisfy the complex needing of all those buildings where it is necessary to neutralize simultaneous opposite thermal loads.‎ QUATTRO, operating in total heat recovery mode, is able to satisfy the simultaneous demand of hot and cold water all over the year, simplifying the plant and reducing operating costs.‎ Available in two different efficiency levels: A.‎ STANDARD EFFICIENCY  B.‎ HIGH EFFICIENCY  Versions MA: Multifunctional air-cooled unit.‎ LN/SL: Acoustic versions.‎ B1/A1/B2/A2: Hydraulic versions evaporator side L1/H1/L2/H2: Hydraulic versions condenser side Advantages High energy efficiency assured by oversized heat exchange coils and high energetic performance fans.‎ EC Fans.‎ Due to the innovative profile, these fans ensure high efficiency by reducing power input and sound emissions.‎ Easy installation and maintenance.‎ Thermocold Adaptive Refrigerant System™: a proprietary technology, which automatically optimizes refrigerant charge and sub-cooling in each operating mode and varying temperature conditions, delivering additional performance and efficiency gains.‎ TER is the unique index officially recognised by Eurovent for measuring the performance of a multi-functional unit while it is working in simultaneous cooling and heating mode.‎ It is calculated as the ratio between the sum of the heating and cooling capacity supplied to the plant and electrical power input.‎ The TER reaches its maximum value when the two opposite loads are completely balanced.‎ The more balanced are the plant loads, the higher is the TER.‎ The multifunctional systems are the most powerful solution with low operating costs, both in terms of plant simplicity that the energy saving due to the total energy recovery.‎   Further info from manufacturer on QUATTRO EA Thermocold
