This commercially orientated system is ideal for larger sites with the need 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
  • New By-pass Ventilation  - reduces cooling load, night purge & office cooling
  • CO2 density sensor

LOSSNAY Technology

  • Two paths ventilation - simultaneously 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.

Energy Saving by Weekly Timer

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