Daikin has upgraded its Rebel Applied rooftop system with enVerid Sorbent Ventilation Technology (SVT), creating a packaged total air-quality system that combines sorbent media with a configurable rooftop unit. The system removes CO2 in buildings, volatile organic compounds (VOCs), and other contaminants using sorbent filtration that captures pollutants while allowing oxygen and water to pass through. The system provides greater humidity control while cutting operating expenses by up to 30 per cent.
