WY Series

The CITY MULTI VRF air conditioning system with a unit that
can be cooled by using water, enabling flexibility in the installation.
The unit can be installed even inside buildings or enclosed spaces.

Water Cooled

The Water-Cooled innovation that switches from cooling with air to cooling with water has resulted in better cooling efficiency and higher levels of energy saving. It combines the strengths of both the CITY MULTI system and the Water-Cooled system in one.

Self-cooling Device

Self-cooling without depending on ventilation system. Installation can be anywhere, even in closed areas.


Operational efficiency is on average 28% higher than air cooling models.

Water Flow Rate Control

The WY Series has a function that can send signals to the Control Valve to reduce or increase the water flow rate based on the load at that time, which helps to save energy even further.
