About Us

RHT Industries Limited thinks from the perspective of customers, focuses on the users’ safety, products’ utility, and the protection of the natural environment. Bringing better products with better technology and ultimately creating a better life for the society.

Company Background

RHT Industries Limited and its subsidiaries are Hong Kong innovative technology companies headquartered in Hong Kong Science Park. Since its establishment in 1998, it has been committed to the development of environmental protection industrial technology, and has an excellent scientific research team, which enables the company to have a more forward-looking vision in the field of air purification technology.

The traditional air cleaning industry generally adopts the technology of “pollution transfer”, which transfers pollutants instead of decomposing them to deal with air pollution, such as high-altitude emission or activated carbon absorbing pollutants. Long-term use will only aggravate environmental pollution and increase meaninglessness. energy consumption.

RHT’s scientific research team worked hard for 20 years and had broken through the shackles of “pollution transfer” and successfully developed the patented technology of NCCO (Nano-Confined Catalytic Oxidation), using a new scientific design and environmental protection thinking to realize the removal of pollutants in the air treatment system. The integration of adsorption and decomposition solves the problem that traditional air treatment operations have been criticized for, and truly purifies the air.

The company’s services have achieved outstanding results in many regions around the world up to now, it has accumulated rich practical experience and engineering contract cases in public institutions, industry, business and private residential industries. As many as 300 hospitals around the world have adopted it, our air purification systems provide protection for medical staff and patients.

RHT is composed of three concepts, namely Regeneration, Hope, and Trust. These three also constitute the brand spirit of RHT. It combines advanced technology of Hong Kong research to create environmentally friendly materials and technology, and is determined to bring new products with better technology. Hope to promote the internationalization of Hong Kong brands, guide the air purification reform in the market, and create a green living environment for the next generation.
