This commercially orientated system can be utilised virtually anywhere to extract stale air and then recover the heating or cooling energy to either warm or cool incoming fresh air.



  • New Hyper Eco Element Core - better energy conservation by improved total heat exchange efficiency
  • Extra Low Mode
  • New By-pass Ventilation  - reduces cooling load, night purge & office cooling
  • CO2 density sensor

LOSSNAY Technology

  • Two paths ventilation - simultaneoulsy intakes Fresh Air and exhausts Stale Air.
  • Total energy recovery - returns BOTH sensible heat and latent heat.
  • Hyper Eco Core - energy conservation performance has been improved by reducing the air conditioning load associated with ventilation and by facilitating humidity penetration.

Extra Low Mode

  • In addition to the conventional Extra High, High & Low modes, an Extra Low mode is added to provide a more dynamic range of air volume settings and versatility in a variety of installation environments, yielding much better energy conservation.

Energy Saving by Weekly Timer

  • Air volume level can be set hourly (max. 8 times) and weekly.
