KAYF- DN3.0

1. Features

New Panel

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

correspondingAC 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.
