The YORK EcoAdvance module captures and removes molecular contaminants from indoor air while intelligently managing the flow of outside air into a building. This process reduces HVAC peak loads by more than 40 percent, resulting in an average of 20-percent to 40-percent annual energy-cost savings. YORK EcoAdvance is easy to install in conjunction with air-handling units, energy-recovery ventilators, or rooftop units. It minimizes the amount of outside air necessary to maintain air quality while meeting and exceeding requirements of ANSI/ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality. Its intelligent, self-cleaning operation automatically removes contaminants from buildings via exhaust and uses smart sensors to continuously monitor system performance and air quality.
