Features
The new Big DI inverter proposes an
alternative cost competitive solution for
medium size applications like shop and
small office buildings.
The big DI system is the ideal solution
in case of a large volume with single
temperature control as it allows
simultaneous operation of 2, 3 or up to 4
identical indoor units.
Toshiba concentrates a set of new high
technologies in one unit, to deliver a top
COP and EER* together with big capacity,
still offering a very compact and flexible
installation; through extensive piping
run and a wide range of indoor units
connection (please refer to page 32).
Thanks to an extended operation
range, the big DI allows comfortable
environment throughout the whole year.
