Features and advantages
Quiet operation
■■ 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.
■■ Si mplified 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
Economical operation
■■ 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
Environmentally balanced
■■ 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
