RHT International Limited

Stand: 4-G62

We are part of RHT Industries Ltd and our headquarter is at the prestigious Hong Kong Science and Technology Park. With our partnership with the internationally known Hong Kong University of Science and Technology (HKUST) and its entrepreneur program, we have developed an innovative air treatment system using patented nano technology called NCCO. NCCO (Nano Confined Catalytic Oxidation) converts pollutants such as Volatile Organic Compounds to harmless Carbon Dioxide and Water molecules. It also is able to remove particulates (PM2.5), smoke, bacteria, allergens and also viruses such as the influenza virus H3N2.

Our filter technology is sustainable, having one of the longest, if not the longest life in the industry, thus reducing running costs and also is kind to the environment. Our air treatment systems have been selected and approved by Chep Lap Kok International Airport and the very busy Mass Transit Railway (MTR) system. Our systems are also used in the International Finance Centre (IFC) in Victoria harbor as well as global hotels chains in the area.

Our focus internationally has been introducing our industrial units to the Life Science sector such as hospitals and now we have successful partners in Europe, Middle-East and Asia.

At The Contamination Expo we will be introducing our new range of smart home air treatment systems, as well as our commercial units. We’d love to talk to suitable partners to sell our products into the household sector in the UK and Europe and so please visit us on stand 4-G62.
