The total heat exchanger unit (HRV/ERV) is an advanced ventilation system that efficiently exchanges both heat and moisture between incoming fresh air and outgoing exhaust air. This energy recovery technology significantly reduces HVAC energy consumption while maintaining excellent indoor air quality.
Our HRV/ERV units feature high-efficiency cross counter flow heat recovery cores that achieve 70-80% heat exchange efficiency. The system comes with PM2.5 filtration to ensure clean, fresh air supply while removing pollutants from outdoor air. The ultra-thin design allows flexible installation without compromising interior space.
The units utilize premium brushless DC motors that operate quietly while saving over 50% energy compared to conventional AC motors. Optional features include CO2 sensor control (up to 5000ppm detection), bypass function for cold climates, and LCD display for easy operation monitoring.
Applications include office buildings, meeting rooms, computer rooms, restaurants, shopping malls, gyms, hospitals and other commercial spaces requiring efficient ventilation with energy recovery.
