One VRF system can provide air conditioning and air supply at the same time.

Outdoor Air Unit can be connected in a same VRF*1 system as one of indoor unit series and can create fresh and comfortable air supply together from our high advanced technology.

Make sure the connected capacity is within the range of 50% to 100% of the outdoor unit capacity. In addition, if there are mixed connections with indoor units, make the Outdoor Air Unit connection capacity 30% or less of the outdoor unit capacity.

High energy savings and flexible duct design by using DC motor

  • Greatly reduces electricity consumption by adopting permanent magnet compared to when using an AC motor.
  • Compared with AC motor,changing the speed makes it possible to respond flexibly to the external static pressure from 0.20 to 0.96 in. WG. (50Pa to 240Pa).Even if damper equipment is not used, static pressure can be adjusted and duct design is easy.
  • Static pressure can be set easily using wired remote controller.
