VRF SYSTEMS INDEX
Superior quality, reliability and durability
Two independently controlled Inverter compressors achieve high efficiency. Redesigned components
in the body provide performance improvement especially in the rated cooling condition and EER
performance.
High safety operation in case of breakdown!
Automatic Back-Up operation. Ensures heating and
cooling.
It is possible for the system to keep working, even if the
compressors, fan motor and the temperature sensor are
damaged (even when a compressor fails in single unit with
2 compressors inside).
The system will still operate with only 25% of the
connected indoor units.
System will not stop when only 25% of indoor units have
power supply and breakdown on other indoor units.

Extended compressor life by uniform compressor
operation time
The total run-time of compressors are monitored by a
built-in microcomputer, which ensures that operation
times of all compressors within the same refrigerant
circuit are balanced.
Compressors with histories showing shorter run times are
selected first, ensuring equal wear and tear across all
units and extending the working life of the system.

* Depend on accumulated operation time of each compressors.
* Compressor priority has possibility to be changed.
(e.g) Case 1: A>C>B>D, Case 2: C>A>D>B, Case 3: A>C>D>B, Case 4: C>A>B>D
* Also other cases available.
A large number of indoor unit models can be connected.
