GENERAL INDEX
3-Pipe ECOi EX MF3 Series superior flexibility
Increased piping lengths and design flexibility
Adaptable to various building types and sizes. Actual
piping length: 200 m. Maximum piping length: 500 m.
Up to 40 m piping after first branch
Up to 52 units can be connected to one system. Flexible
piping layout makes it easier to design systems for
locations such as train stations, airports, schools and
hospitals.
Maximum height difference between
outdoor unit and indoor unit:
1)
50 m
Maximum height difference
between indoor units:
15 m

1) 40 m if the outdoor unit is below the indoor unit.
Excellent cost saving and smaller piping size
By using R410A with low pressure loss, pipe sizes for
discharge, suction and liquid are all reduced.
This makes it possible to aim for reduced piping space,
improved workability at the site, and reduction of the
piping material costs.
High external static pressure on condensers
With an efficient fan shape, fan guard, motor, and casing,
the models can be custom-installed on-site to provide up
to 80 Pa of external static pressure.
