Poly Art Space in Shenzhen's Uniwalk mall rotates exhibitions constantly — and every new show means fresh paint, new adhesives, and construction materials. Each fit-out flooded the galleries with VOCs right before doors opened to the public. With families and young children among the visitors, the venue couldn't afford to compromise on air safety. The challenge: keep the air clean without slowing down the exhibition calendar.
RHT designed a multi-zone NCCO system combining duct-mount units (RH-220, RA-920) for incoming ventilation air with ceiling-mount units (RH-490C) for recirculated air. The NCCO reactors decompose VOC molecules on contact — they don't just absorb them temporarily. Within days, indoor air quality met international standards, and the venue now runs back-to-back exhibitions without worrying about air safety.
