Nano-Titanium Filter (Air Exchanger range only)
In our new Air Exchanger models we
have introduced the Hitachi state
of the art Nano-Titanium Catalyst
which dramatically improves the
functions of deodourisation, bacteria
elimination and anti-bacterial
measures. Titanium Oxide has been
used as a photocatalyst for many
years but Hitachi have now enhanced
it by reducing its size to a nanometer
– over 1000 times smaller than
ordinary bacteria agent.
This ultrafine catalyst can therefore
catch smaller microbes or bacteria
which may escape from other filters
leading to higher air quality circulating
around the room.
Automatic Operational Control
Auto restart
If the auto start mode is selected at
the ON/OFF switch, then the unit
automatically resumes operation in the
mode that was in use before it was
switched off. This saves time for the
user on start up and setting selection.
Auto changeover
The built-in microcomputer
continuously selects the best
operating mode to achieve the
required heating and cooling
temperature. The sensor checks
the operating mode periodically
to provide maximum comfort
for the user. (Applicable to all DC
Inverter models.)
The comparison table easily shows
the size of the Nano Titanium
Catalyst in relation to other
ordinary anti bacterial agents
and also details the size of some
common bacteria in relation to
the size of the filter and showing
what does get through.
The Nano-Titanium does not
deteriorate or run out as particles
and dead fungi do not accumulate
on the surface, so it can be used
semi-permanently.
Both the SPX-CFH15 and
SPX-NFH1 filters are included.
Easy to use remote control
All units come with a standard easy to use wireless or wired remote control,
equipped with 24hr timer. All commands are shown on the liquid crystal
display while convenient, frequently-used functions (sleep mode timer,
fan speed and louver control) can be operated with one touch buttons.
