Dual-Zone Air Treatment for China Tobacco's New Office

China Tobacco International moved into a new office at China Life Centre in Hung Hom — and immediately hit two air quality walls. Fresh renovations and new furniture flooded the workspace with formaldehyde and VOCs. Meanwhile, the dedicated smoke evaluation room filled with cigarette particulates that leaked through the doors into surrounding offices. Two distinct problems. One budget.

RHT tackled both issues with a two-zone NCCO strategy. Ceiling-mount RH-490C units across the general office neutralise renovation off-gassing and lingering smoke odour. A dedicated duct-mount RH-220 inside the evaluation room captures and decomposes cigarette particulates at source — stopping cross-contamination before it starts. Two problems solved. One integrated system.
