Tuen Mun Hospital's busy ground-floor washrooms serve thousands of patients and visitors daily — and the smell traveled. Odour and bacteria from the washrooms seeped into the adjacent lobby and waiting areas. Patients complained. Staff morale suffered. And none of the conventional ventilation upgrades made a dent, because the problem started at the source: the fixtures themselves.
Instead of trying to treat the air after it spread, RHT engineered NCCO units that mount directly at the urinals and toilets — killing odour-causing compounds at the point of origin. The system also slashes airborne bacteria and, as a bonus, reduces the HVAC energy load because the hospital no longer needs to over-run ventilation to compensate. Source treatment beat room treatment.
