Executive Summary
A premier healthcare provider in northern Thailand, renowned for advanced clinical services and international patient care. With over a decade of service excellence, the hospital prioritises patient safety, infection control, and operational sustainability across its facilities.
As part of its commitment to Green Healthcare initiatives and operational resilience, the hospital partnered with PCS to introduce robotic cleaning systems and ozone-based cleaning technologies; a strategic move to address workforce shortages, reduce chemical dependency, and enhance environmental health within high-pressure hospital environments.
The Brief
The hospital faced two main challenges: a shortage of staff to meet growing cleaning demands and pressure to comply with national infection prevention and sustainability standards.
Key performance risks included:
Key Results
-
90%
of general areas adopted ozone cleaning
-
30%
manpower time savings through robotics
-
100%
chemical-free products in ozone-cleaning zones
-
24/7
cleaning in high-traffic areas such as inpatient corridors and outpatient lobbies
Our Approach
PCS introduced an integrated innovation framework that combined autonomous cleaning robotics with ozone-based cleaning protocols. The AI-driven robots, equipped with UV-C technology, provided continuous 24/7 cleaning in high-traffic areas such as inpatient corridors and outpatient lobbies, delivering 30% man-hour savings and eliminating chemical use for selected tasks. This automation freed staff to focus on critical-zone detail work.
Meanwhile, stabilised aqueous ozone replaced up to four to five chemical products in daily routines across corridors, lobbies, meeting rooms, and offices, improving air quality, reducing water consumption, and preventing chemical runoff.
The Outcome
The initiative resulted in 90% of general areas adopting ozone cleaning, 30% manpower time savings through robotics, and complete elimination of chemical products in ozone-cleaning zones, with staff reporting improved air quality and reduced chemical odour.
