Helps Shortest Route Design Free Branching |
|
| |
| Combination of line and branching pipe connection makes the shortest design route possible, thereby saving on installation time and cost. |

Simple Wiring |
|
| |
| Multiplex communication system makes it possible to connect multiple indoor units to one outdoor unit with a 2-core wire, thus simplifing the wiring operation. |

High Lift Design |
|
| |
| 175 m Equivalent length and 50m Height difference is allowed in ETA GREE GMY. Level difference between indoor units of 15m makes the location of the system more flexible. |

Energy Saving |
|
| |
Each room can be controlled individually, so that only those rooms requiring air conditioning are cooled or heated.lnaddition,thanks to the stepless regulation technology of ETA GREE and EXV (Electronic Expansion) applied in both indoor and outdoor units. The temperature of each room can be precisely controlled. High IPLV is achieved by employing cutting-edge technology, and contributing to smooth and economical operation. The highest IPLV value 4.6 W/W (15.69 BTU/W-hr) ,compared with the conventional chillerfan coil system, a large energy saving can be realized |

Compact Design |
|
| |
We offer a wide range of outdoor and indoor units to meet the needs of building size and interior design. Long refrigerant pipe is applicable to ensure better flexibility.
In most situation, no special cranes or conveyer is needed to lift the outdoor unit to the roof as it can be carried by elevator in the building thanks to compact design.
Compact connection refrigerant piping system ensures GMV with great advantage of saving ceiling space, especially in low profile buildings. |

Intelligent Control |
|
| |
ETA GREE GMV intelligent controls and modulating valves deliver the required capacity, according to the load variation from 10% to 100%. The intelligent controls and modulating valves limit or increase the cooling capacity dynamically, so humidity and temperature are kept in the comfort range.
Electronic expansion valves respond to the changes in load of indoor units and continually control the flow rate of refrigerant. In this way, we can get a nearly constant room temperature with the GMV system without common temperature fluctuation that occurs with a conventional ON/OFF control system. The precise PID controls maintain the room temperature within ±O.soC of the set temperature. |

Wide Control Application |
|
| |
- Intelligence Network system
- Central control available ( provided with weekly timer function)
- Network monitoring system available
- Wireless remote controller or wired controller of indoor units
- Diagnostic software for service purpose is known as Debugger S/w
- Region wise wired controller i.e. Smart Zone controller

Larger capacity |
|
| |
Rm series and Pdm series are modular design. Maximum 4 basic modules can be freely combined together to achieve max. Capacity of 180kW. (64 Hp) With advanced controls, the outdoor modules have no differences & there is no need |
|
| |
DC Inverter fan |
|
| |
Thanks to high-efficiency DC inverter fan motor, the outdoor units are high efficiency and low noise; the ESP(external static pressure) is up to 50Pa, that ducting installation for hot air exhaust can be satisfied. |
