Working Principle
Supply air and exhaust air flow perpendicular to each other across the heat exchange core.Heat transfers through partition plates without air mixing, recovering waste heat for fresh air preheating / precooling.
Main Features
Air flows cross at 90°, simple structure and easy installation
Moderate heat recovery efficiency: 50%–75%
Compact size, low cost, widely used in standard ventilation systems
No moving parts, low maintenance, long service life
Complete air isolation, no cross contamination.
Material Options
Aluminum alloy: standard HVAC ventilation, cost-effective
Stainless steel: industrial corrosive, high humidity environment
Plastic / polymer: lightweight, anti-corrosion for special air media
Application Scenarios
Residential & commercial ventilation HRV/ERV systems
Office buildings, shopping malls, hotel fresh air units
Industrial factory ventilation, exhaust heat recovery
Air handling units (AHU), rooftop air conditioners
Greenhouse, livestock farm energy-saving ventilation
