The product has been designed with Energy Exchange System(same as mask works). The high efficiency shows up to the above amazing 96% of heat energy preservation ratio of our product has ever been recognized officially by ORTECH INT’L, Canada which is a R&D and Testing and Appraised Organization. While the products got approval of ‘High Efficiency Energy Certificates’ issued by KEMCO.



* E.R.V. (Energy Recovery Ventilation) System



- As the wheel with ‘Polyester Fiber’ begins to turn, the heat exchange core conveys heat.

- 90% of temperature is conveyed, and when cooling, the exhausting cool air cools and dries the inflowing air and when warming, the exhausting air warms and humidifies the inflowing air.



* Economic operation and Enjoy healthy life by high efficiency



- Warming and cooling cost is reduced thanks to conservation of indoor energy and ventilation maintaining 96% of indoor energy.

- It supply fresh air by exchanging 1 of supply of purified outdoor air to 1 of exhausting out of indoor air, Indoor humidity is kept constantly in spite of dry climate.



* By Pass system(for Spring/Fall seasons in a year)



- The machine has a by-pass function inflowing outdoor temperature to indoor with one touch button, which possible to operate in-direct cooling and warming in Spring/Fall.
