Features and advantages
Compressors - Low-noise scroll or rotary compressors with low vibration levels - The compressor assembly is supported by antivibration mountings. Air heat exchanger section - Vertical air heat exchanger coils - The latest-generation low-noise fans are now even quieter and do not generate intrusive low-frequency noise - Rigid fan installation for reduced start-up noise. Simpliﬁed electrical connections - A single power supply point (power supply without neutral available as an option and in standard for units size 40kW) - Main disconnect switch with high trip capacity - Transformer for safe 24 V control circuit supply included Fast commissioning - Systematic factory operation test before shipment - Quick-test function for step-by-step veriﬁcation of the instruments, electrical components and motors.
Easy and fast installation
Integrated hydronic module - High-pressure centrifugal water pump - Water ﬁlter protecting the water pump against circulating debris - High-capacity membrane expansion tank ensures pressurisation of the water circuit - Overpressure valve, set to 4 bar - Pressure gauge to measure the system pressure. - Automatic purge valve positioned at the highest point of the hydronic module to remove air from the system. - Thermal insulation and frost protection down to -10°C, using an electric resistance heater and pump cycling. - Integrated water ﬁll system to ensure correct water pressure (option) Physical features - With its small footprint the unit blends in with any architectural styles. - The unit is enclosed by easily removable panels, covering all components (except air heat exchanger and fans).
Increased energy efﬁciency at part load - Eurovent energy efﬁciency class A and B (in accordance with EN14511-3:2013) in cooling and heating mode. The exceptionally high energy efﬁciency of the AquaSnap unit is the result of a long qualiﬁcation and optimisation process. Reduced maintenance costs - Maintenance-free scroll compressors - Fast diagnosis of possible incidents and their history via the Pro-Dialog+ control - R410A refrigerant is easier to use than other refrigerant blends
Non-ozone depleting R410A refrigerant - Chlorine-free refrigerant of the HFC group with zero ozone depletion potential - Very efﬁcient - gives an increased energy efﬁciency ratio (EER) Leak-tight refrigerant circuit - Brazed refrigerant connections for increased leaktightness - Veriﬁcation of pressure transducers and temperature sensors without transferring refrigerant charge
