Each module is provided with two high-efficiency inverter scroll compressors developed by Mitsubishi Electric and can operate optimally according to the load. This improves the high energy saving performance. 

High EER, High COP 

• The air suction area is expanded to maximize the performance of the air heat exchanger. 
• Two independent refrigerant circuits are provided in the module to cool and heat water in two stages in series to improve EER and COP.

High SEER 

• Achieved the same SEER from 30 to 180 HP.

Suppression of heating capacity drop at low outside temperatures  

• A heat pump technology captures heat from the outdoor air. The heating performance decrease which occurs with a decrease in outdoor air temperature has been made up for by installing a larger number of units. This disadvantage has been eliminated with the e-series by increasing the heating performance in the low outdoor air temperature range. This allows the user to reduce the required number of units.

High Efficiency Inverter Compressor  

DC inverter scroll compressor is incorporated. Two compressors each are incorporated to increase efficiency.  

Two refrigerating cycles  

A configuration of two independent refrigerant circuits and the series connection of water-side heat exchangers increases the performance (two-stage cooling). 

U-shaped High Performance Compact Air Heat Exchanger  

U-shaped air heat exchangers are used. Installing them in a row makes the system thinner. Weather resistant coating is provided for the heat transfer plate fin as standard.  

Inflexed Fan  

Adoption of a fan with improved ventilation characteristics and a newly designed trailing edge that suppresses wind turbulence raises fan operation efficiency. 

Fan Inverter Control 

Air blower fans are also equipped with an inverter to save energy. 

The total capacity can be increased to up to 30HP × 6 modules = 180HP. Because modules can be installed horizontally in a row. Installation in narrow places such as along building walls is possible.
