1. Features
Various selection
Three styles of panels to choose.
Flexible installation
Multi-refrigerant outlet pipe method: left\right\rear, more flexible for installation.
Flexsible piping connection
Refrigerant piping and condensate piping on the same side
High efficiency DC fan motor
The power consumption of DC driven VRF indoor units can be reduced up to 30% in comparison to
corresponding AC type.
Quiet operation
Adoption of the 2000 stages element positioning mechanical expansion valve, ensures precise flow control, as
well as lower modulation noise when EXV operating.
More smooth airflow with less turbulence. Owing to the multiple-blade fan and the air guide design, the airflow
is getting smoother and more comfortable.
