Galletti presents VLE new range of air-cooled monobloc chillers and heat pumps with low environmental impact
Gamma VLE di Galletti: chiller e pompe di calore reversibili monoblocco condensate ad aria per installazione a esterno
The range VLE, Air-water unit with high seasonal efficiency and low-GWP R454B refrigerant, consists of 11 models with cooling capacities ranging from 150 to 570 kW, available in cooling only or reversible heat pump versions.
The range's main strength is its high seasonal efficiency, which is designed to permanently reduce annual energy consumption as well as meet the minimum efficiency requirements established by ErP 2021. In order to increase the efficiency at partial loads, all VLE models are provided with tandem or trio solutions (2 or 3 compressors on a single circuit) and equipped with electronic expansion valve as standard.
The use of top quality components at the cutting edge of technology in the cooling, hydraulic, and electrical systems makes VLE chillers state of the art in terms of efficiency, reliability, and operating limits. In fact, the ability to produce water from -10 °C to 55 °C and operate at full load with outdoor air temperatures from -15 °C to 46 °C is guaranteed.
The range provides high configurability from the point of view of acoustics, with a wide range of accessories designed to reduce noise emissions. Advanced control, which is always provided across the entire range, allows continuous monitoring of operating parameters, advanced regulation logics, and connectivity.
Lastly, the modular structure with V-shaped coils is designed to optimize heat exchange on the air side, guarantee structural strength with a reduced footprint, and maintain maximum accessibility of the key components.
