Features
• Twelve sizes with nominal cooling capacities from 38 to 149 kW and nominal
heating capacities from 42 to 158 kW.
• Aquasnap heat pumps for commercial or industrial applications.
• Increased energy efficiency at part load - Eurovent energy efficiency class C
and D (in accordance with EN14511-3:2013) in cooling mode and B and C in
heating mode.
• 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).
• Low-noise scroll compressors with low vibration level.
• Vertical air heat exchanger coils 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 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.
