High Energy Efficiency
Hitachi conforms to the
2002/31/EC Directive – 92/75/EEC
“Energy labelling Directive (ELD)” ,
which is applicable from June 2004
on all air conditioning products up
to 12Kw cooling capacity. The DC
inverter PAM technology helps us
to achieve the ‘A’ class, the highest
level of energy efficiency which is
clearly indicated on the standard
labelling system.

The variable speed compressor
(inverter) enables the system to
rapidly reach the desired room
temperature setting. Once the
desired room temperature has been
achieved the compressor rotation
speed is reduced, saving up to 30%
in energy usage (when compared to
conventional systems) without
compromising comfort levels.

The inclusion of a DC driven motor
delivers an enhanced performance
over standard AC motor driven
systems. This enhanced performance
can be as much as 10%!

Hitachi’s PAM (Power Active Module)
control system mirrors the current
pulse waveform to avoid distortion
and therefore achieve almost
100% power factor to enhance
power efficiency. This cutting edge
device is employed in all Hitachi
Mono/Multizone products for your
comfort and energy saving for our
environment. It ensures the efficient
use of input power and minimises
loss to less than 1%. The PAM
range boasts an industry leading
COP of more than 4.0.
All DC Inverter
As you would expect from an
Industry leader such as Hitachi,
we have been at the forefront of
technological development and
advancement. As the pioneer
of ‘DC’ Inverter driven Room
Air Conditioners, our units boast
the significant advantage of all
DC Inverter driven compressors
and fans. Enhanced inverter
performance and system
performance are achieved by
the addition of a ‘DC’ drive.
