Features and advantages
Features
Easy and fast installation
The main features of this product range are:
■■ Integrated hydronic module (option)
-- Multi-speed centrifugal water pump, based on the
pressure loss of the hydronic installation.
-- Water filter protects the water pump against
circulating debris.
-- Pump protected against cavitation by a pressure
transducer that measures the entering water pressure.
-- Overpressure valve, set to 4 bar.
-- Thermal insulation and frost protection down to
-20°C, using an electric resistance heater (see table of
options).
■■ Physical features
-- The unit has a small footprint and a low height (1329
mm) 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 without neutral.
-- 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.
■■ 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
an optional hydronic module with a multi-speed pump.
■■ 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.
-- Intelligent unit control permits unit operation in extreme
conditions, minimising unit shut-down times.
-- Hot water production at 65°C is available
continuously.
HEATING
Carrier quality is your guarantee for the safety and durability
of the installation.
The AquaSnap high-temperature heat pumps incorporate 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 AquaSnap high-temperature heat pumps can be
equipped with a hydronic module that is integrated into the
heat pump chassis, limiting the installation to straight-forward
operations like the wiring and the connection of the hot water
supply and return piping.
Quiet operation
■■ 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, made of a
composite material (Carrier patent), are now even quieter
and do not generate intrusive low-frequency noise.
-- Rigid fan installation for reduced start-up noise
(Carrier patent).

Economical operation
■■ Increased energy efficiency
-- Eurovent energy efficiency class A (in accordance with
EN14511-3:2011).
-- 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.
Environmentally balanced
■■ 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 for increased leaktightness.
-- Reduction of leaks due to elimination of capillary
tubes (TXVs).
-- Verification of pressure transducers and temperature
sensors without transferring refrigerant charge.
