Features and advantages
The main features of this product range are: Energy savings The 61AF range is certiﬁed to the Eurovent energy efﬁciency class A with a coefﬁcient of performance (COP) of over 4. This complies with the COP required by the Ecolabel certiﬁcation. Ease-of-installation The high-temperature AquaSnap heat pumps incorporate a hydronic module with a variable speed pump, in option. Easy integration The low noise levels of the 61AF heat pump and its very compact chassis reduce the noise disturbance from the unit. Application ﬂexibility The operating range allows outside temperatures down to -20°C and leaving water temperatures up to 65°C for domestic hot water applications. Availability - Intelligent unit control permits unit operation in extreme conditions, minimising unit shut-down times. - Hot water production at 65°C is available continuously.
Easy and fast installation
Integrated hydronic module (option) - Variable speed water pump, based on the pressure loss of the hydronic installation. - Water ﬁlter protects the water pump against circulating debris (option). - Overpressure valve, set to 3 bar for the 61AF 014 and to 4 bar for the 61AF 019. - Thermal insulation and frost protection down to -20°C, using an electric resistance heater. Physical features - The unit has a small footprint and a low height (1103 mm for the 61AF 014 and 1550 mm for the 61AF 019), allowing it to blend in with any architectural styles. - The unit is enclosed by easily removable panels, covering all components (except condensers and fans). Simpliﬁed electrical connections - Single power supply point with neutral. - Main disconnect switch with high trip capacity (standard only for 61AF 019). - 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.
Carrier quality is your guarantee for the safety and durability of the installation. The high-temperature heat pump range incorporates the latest technological features: - scroll compressors with vapour injection - low-noise fans made of a composite material - auto-adaptative microprocessor control - electronic expansion valve - multi-speed pump. The high-temperature AquaSnap heat pumps can be equipped with a hydronic module that is integrated into the heat pump chassis, limiting the installation to straightforward operations like the wiring and the connection of the hot water supply and return piping.
Increased energy efﬁciency - The exceptional energy efﬁciency level (COP) of the high-temperature AquaSnap heat pumps in the heating mode is the result of a long qualiﬁcation and optimisation process. - The electronic expansion device (EXV) allows operation at a lower condensing pressure (COP optimisation). - Dynamic superheat management for better utilisation of the condenser surface. Reduced maintenance costs - Maintenance-free scroll compressors with vapour injection. - Pro-Dialog+ control offers fast diagnosis of possible incidents and their history.
Compressors - Low-noise scroll compressors with low vibration level. - The compressor assembly is installed on an independent chassis and supported by anti-vibration mountings. - Dynamic suction and discharge piping supports, minimising vibration transmission (Carrier patent). Evaporator section - Vertical evaporator coils - Protection grilles on anti-vibration mountings to protect the heat exchanger against possible shocks. - Latest-generation low-noise Flying Bird fans are now even quieter and do not generate intrusive lowfrequency noise. - Rigid fan installation for reduced start-up noise.
Non-ozone depleting R-407C refrigerant - Chlorine-free refrigerant of the HFC group with zero ozone depletion potential. - Very efﬁcient - ensures an increased energy efﬁciency ratio (COP). Leak-tight refrigerant circuit - Brazed refrigerant connections
