Cooling capacity ranges
Running current comparison.
The cooling & heating capacities at the maximum operating
speed have also been improved by up to 33% compared
to the current model.
Operation is now possible at lower speeds, thus cutting
energy losses produced by the repeated on/off operation
of non-inverter models. Comfort is improved while power
consumption is reduced.
Higher Cooling & Heating Power Wider Performance Range
3 phase power supply
"Power Inverter"
(RP100 - 250YHA)
The other features;
*
Replace filter equipped (to Reuse the existing pipe works)
*
High efficiency operation
*
Silent operation (Only 52dB in silent mode: 20.0kW)
Compact top flow models
(20 & 25kW Power Inverter)
By additional filling with refrigerant, it is now possible to
have pipes up to 120 metres long, making it easier to
select a layout to install the unit.
Dramatic reduction of running current is realized by 3
phase power supply. The special technology is installed in
the outdoor unit to comply with the Electro Magnetic
Compatibility in Europe.
Harmonics Filter Technology
We have successfully complied with
the EMC regulations (EN61000-3-
2,Class-A) first in the industry in the
category of 3 phase inverter driven
air conditioners requiring less than
16A current input.
Less than half in the running current and the breaker size !!
