DC Compressor (24 &
30 HP Units) |
|
 |
| By using DC, the performance
is improved at around 30-40 Hz where the operation
time of the invertor compressor is longest. Also,
to suppress electromagnetic noise interference and
achieved low noise, the rotor has been divided into
two and the electric pole displaced. |

|
High-performance
Heat Exchanger |
|
|
| A new high-performance
heat exchanger has been developed with improved
piping arrangement . |
|
|
|
|
Self-diagnostic
System |
|
|
| The self-diagnosis
result is shown on a digital display via control
from either a remote control (relating to
indoor units) or one of the outdoor units.
This air conditioning system can be checked
for operation even through the printed circuit
board in the outdoor unit, allowing you to
carry out inspection work and/or take remedies
more quickly and correctly. |

|
|
Compact Size And
Lightweight |
|
|
| Outdoor units
have become even more compact and lightweight.
Outdoor units require a 33% smaller installation
space compared to conventional types and weigh
about 24% less (for 10FSG/FS3). They are easily
installed in cramped spaces and are small
enough to be carried by ordinary elevator
to the installation location. |
|
 |
|
| SET- FREE comes
with seven options of the indoor unit. you
are sure to find one made just for you, as
per your requirements of tonnage and aesthetics. |

The Quietest In
The Industry |
|
|
| A new stream fan
and enilarged bell-mouth is used in this series.
The fan rotatIon control has been changed
to PWM (Pulse Width Modulation type. These
improvements contribute to the quietest operation
(58 dB). Furthermore, specific attention is
paid to nighttime operation. If the outdoor
temperature does not exceed 30 degree Celsius
during cooling, this model will operate in
night-shlft mode by night-shift setting, enabling
it to run at low noise level of 53 dB. |

|
Environment Friendly |
|
|
| Hitachi has introduced
the FSG and FSGI series that has been specially
developed with the global need to help protect
the earth's environment by using non-Ozone
depleting refrigerant R-22. |
|
|
|
|
Energy Saving Control |
|
|
| The compressor
can be operated by optimizing control over
its service frequency depending on the capacity
of indoor units. Optimizing reduces the power
consumption, achieving 81% annually. |
|

|
|
Greater Flexibility
Of Installation |
|
|
| The actual piping
length has been extended from 100m to 120m.
The distance between the first branch unit
and terminal unit can be 40m. Hence, installation
is flexible. |
