Water Cooled Series
The new water cooled outdoor unit offers a greater efficiency with a higher COP compared to our YGM
conventional model.
System Pipe Lengths
*1 When the outdoor unit is installed below the indoor unit, top-bottom differential is 40m
[131ft].
*1 When the outdoor unit is installed below the indoor unit, top-bottom differential is 40m
[131ft].

COP comparison (energy efficiency)
Downsized by approximately
57%*, the new models enable
an effective use of space.

Compact design
Weight reduction
The reduction in weight leads to easy transportation and installation.
