Units include inverter fans to maximise EERs and COPs at all operating conditions. • Eurovent energy efficiency class A and B in cooling mode and A in heating mode (in accordance with EN14511-3: 2013) • Integrates the latest technologi­ al innovations: ozone-friendly refrigerant c R-410A, scroll compressors, low-noise fans made of a composite material, autoadaptive microprocessor control, electronic expansion valve and variablespeed pump (option). • Available static pressure of up to 240 Pa for sizes 039 to 050 and 080 to 120, and up to 180 Pa for sizes 060 to 078 and 140 to 160. • Low-noise scroll compressors with low vibration level. • Vertical air heat exchangers with protection grilles on anti-vibration mountings. • Low-noise Flying Bird IV fans, made of a composite material. Rigid fan installation for reduced start-up noise. • Small unit footprint and a low height (1330 mm), enclosed by easily removable panels. • Simplified electrical connections. • Systematic operation test before shipment and quick-test function for stepby-step verification of the instruments, electrical components and motors. • Several compressors connected in parallel. At part load, around 99% of the time, only the compressors that are necessary operate, ensuring increased energy efficiency. • The electronic expansion device (EXV) allows operation at a lower condensing pressure (EER and COP optimisation), and dynamic superheat management optimises the utilisation of the water heat exchanger surface. • Maintenance-free scroll compressors and fast diagnosis of possible incidents and their history via the Pro-Dialog+ control reduce maintenance costs. • Leak-tight refrigerant circuit. • Corrosion resistance tests, accelerated ageing test on compressor piping and fan supports and transport simulation test on a vibrating table in the laboratory. 90
