Cooling is efficient even in winter when
indoor temperatures are higher than those
outside, such as in underground public
spaces or offices with many computers.
Depth of 71F, 100F, 100K-160K are
standardised as 320 mm. Horizontal
continuous mounting is available.

Additional refrigerant charging is required if the
refrigerant pipe is longer than the length.
If refrigerant piping length does not exceed
30 m, there is no need for on-site gas
charging.
Designed for lightness, carry in is easy
Succeeds in trimming 27 kg off weight of
previous equipment
(Applicable to RZQ100K–160K outdoor units)
A pump-down switch is provided to make it
easier to collect refrigerant if the unit is to
be moved or layout modified.
Facilitates pump down
(Refrigerant recovery function)
Effective gas monitoring reduces the labor
required for operation, maintenance, and
repairs.
Low gas level detection function
Operation range
Suited for year-round cooling
applications
Reduced installation work thanks to light,
compact outdoor unit.
Space saving
Compact design with reduced height
Complies with MEPS
The maximum capacity is maintained
within a set level of power consumption,
which makes it possible to keep comfort
and effective demand control.
The outer panel for the piping connection
part of the front, right side and backside
can be removed
and is easier for
post-installation
piping work.

Fittings can be mounted on the four
locations, right/ left on front and back side
of the outdoor unit.
Reinforcing wire fittings
(option) are available
Safety
As the bottom frame is
subject to corrosion,
corrosion-proof galvarium
steel plate is adopted to
enhance the durability.

These two features work to significantly reduce
noise. Guides are added to the bell mouth intake
to reduce turbulence in the airflow generated by
fan suction. The Aero Spiral Fan features fan
blades with the bent blade edges, further reducing
turbulence.

Refined ventilation mechanism enables further reduction in required fan
power.
Escaping eddies are sucked in by
the bent blade edges, reducing
overall turbulence.
A collection of cutting-edge technologies
acheives efficient and quiet operation.

Sine wave DC inverter
>> Smooth sine wave DC inverter
Use of an optimised sine wave
smoothes motor rotation, further
improving operating efficiency.
Use of neodymium magnets in the motor
enables efficient generation of high torque,
reducing the size of the compressor.
>> Powerful magnets
Changes to the shape of the spiral and volume
ratio result in optimal refrigerant layout.
>> Optimal refrigerant configuration
The strength of the casing has been increased
by boosting the internal dome pressure.
>> Stronger materials
Sucked gas is compressed in the
scrolling part before the heated motor,
so that the machine compress
the non-expanded gas, resulting
high efficiency compression.
>> The structural scroll
Energy savings is
realised, eliminating
the friction and the
leakage of
refrigerant gas.
>> Swing compressor
Overheating losses are reduced by pressurising the area
around the motor, energy saving performance in conjunction
with other features.

Neodymium magnets are
much more powerful than
the commonly used ferrite
magnets.

By introducing high pressure oil, the
reactive force from the fixed scroll is added
to the internal force, thereby reducing
thrust losses. This results in improved
efficiency and suppressed sound levels.
