The Hitachi Multizone range was the worlds first all DC Inverter Multisplit
system with zone by zone cooling or heating for up to four rooms.
Hitachi DC scroll and DC twin-rotary compressor, together with award-
winning DC inverter PAM technology, aid the achievement of a system
power factor of almost 100%, thus providing unparalleled performance
and efficiency. The all DC Inverter system ensures extremely sensitive
and accurate temperature control through fuzzy logic and offers
remarkably low sound levels.
The wide range of units have been designed for cooling operation under
low temperatures, down to -10°C. This feature enables cooling to be
obtained even in winter on buildings with high internal heat gains due to
lighting, people and machines, particularly in areas such as shops and
lecture rooms. The heating operation under low temperature, down to
-15°C can also be performed.
The recent integration of Multizone and Monozone employing R410A
refrigerant provides a comprehensive selection of DC inverter PAM mono
and multi split systems, maintaining full compatibility of indoor unit
throughout the range.
Monozone/Multizone compatible indoor unit range caters for all requirements
offering wall mounted, floor standing, 60cm x 60cm cassettes, and in the
ceiling duct units, designed to offer elegance and comfort to any application.

You can choose and connect freely from different types of indoor and outdoor
units depending on the number of rooms, width and shape of the room.
The single Monozone outdoor units work on a 20m to 30m maximum
length of piping, and are made in four different capacities.
Multizone outdoor units can have a maximum chargeless piping length
up to 70m when one outdoor unit is used with four indoor units in various
locations. A maximum combination of indoor units can provide a wide
selection of 6.5kW to 12.0kW.
