REVERSIBLE AIR-TO-WATER HEAT PUMPS 30AWH 004-015
■■ Advanced technology providing maximum energy-efficiency
with high capacity available at peak conditions and
optimised efficiency at low and mid compressor
speeds. The AquaSnap PLUS heat pump DC inverter
uses Intelligent Power Drive Unit (IPDU) hybrid inverter
technology, combining two electronic management
logics: Pulse Amplitude Modulation (PAM) and Pulse
Width Modulation (PWM) for optimised compressor
operation in all conditions, minimised temperature
fluctuations, and providing perfect individual comfort
control with significantly reduced energy consumption:
-- PAM: pulse amplitude modulation of the direct current
controls the compressor at maximum load conditions
(start-up and peak load), increasing the voltage at
fixed frequency. The compressor works at high speed
to rapidly achieve the desired temperature.
-- PWM: pulse width modulation of the direct current
controls the compressor at partial load conditions,
adjusting the frequency at fixed voltage. The
compressor speed is fine-tuned and the system
provides high-level comfort (no temperature fluctuations)
at exceptionally efficient working conditions.
■■ Exceptional endurance tests
-- Third-party testing and certification - all performances
are certified by Eurovent and unit safety is certified by
IMQ.
-- All units are tested at various stages on the production
line for circuit leakage, electrical compliance, water
and refrigerant pressures.
-- End-of-line test of all unit operating parameters.
-- Corrosion resistance test.
-- Accelerated ageing test on critical components and
complete assembled units, simulating thousands of
hours of continuous operation
-- Packaging crash test to ensure that the units are
adequately protected against accidental shocks.
-- Extensive field and site testing.

Economical operation
■■ Increased energy efficiency at part load
-- The exceptionally high energy efficiency of the
AquaSnap PLUS heat pumps is the result of a long
qualification and optimisation process.
-- Use of ambient air as primary source of energy in
domestic heating applications significantly reduces
the overall energy consumption and minimises CO2
emissions.
-- Night mode operation at reduced compressor speed,
resulting in low-noise operation and a significant
reduction in energy consumption.
-- Easy-to-set and economical silent mode, reducing the
compressor speed.
-- R410A refrigerant is easier to use than other
refrigerant blends.

CONTROLS
■■ Compressor frequency is increased continuously up to
the maximum level. This ensures that there are no current
draw peaks in the start-up phase and safe connection
to a single-phase power supply even in large-capacity
systems. The maximum operating current of AquaSnap
PLUS systems is below 7.2 A (systems up to 4 kW) and
below 23 A for larger systems (12 kW). Inverter rampup speed makes soft starts unnecessary and ensures
immediate maximum power.
■■ The two rotary compression cylinders, offset from each
other by 180°, and the DC brushless motor with the shaft
in perfect balance ensure reduced vibration and noise,
even at very low operating speeds. This results in an
extremely wide range between minimum and maximum
capacity with con- tinuous operation, guaranteeing that
the system is always optimised and provides maximum
comfort at exceptionally high efficiency levels.
■■ Twin-rotary cylinders, low vibrations and low load to the
shaft ensure highest compressor reliability and a long
trouble-free operating life.
■■ All DC brushless twin-rotary compressors are equipped
with crankcase heaters as standard.
■■ A double compressor shield for acoustic insulation further
reduces noise levels.
