The Korea Institute of Materials Science (KIMS, President Lee Jeong-hwan/hereinafter referred to as KIMS), a government-funded research institute under the Ministry of Science and ICT, has entered into a verification test where the conductive air purification module technology, which was developed as a source technology and led to the establishment of a research institute, can be objectively compared with existing air purification modules by applying it to a domestic general hospital.

Alink Co., Ltd. (CEO Lee Hye-moon) decided to test-apply its own Airclisen air purification module system technology to Changwon Hanmaeum Hospital (Chairman Ha Chung-sik).

Alink Co., Ltd. is a materials specialized company founded based on the original aluminum 3D special coating technology developed by Materials Research.

Materials Research Institute has developed 3D aluminum coating material technology through a support project from the Ministry of Science and ICT and the Ministry of Trade, Industry and Energy.

In addition, we have continued to support Alink Co., Ltd., a research institute start-up company established based on the original technology, and have successfully commercialized a conductive air purification module exclusively for hospital building air conditioning systems that completely removes fine dust, bacteria, and viruses in the air and significantly reduces power consumption and greenhouse gas emissions.


Conductive air purification modules using this technology have been installed and tested in general large buildings, hotels, subway stations, etc. from late 2021 to the present. However, this is the first time that a verification test has been conducted in a special building, such as a hospital, that is directly related to people's health.

In early July, Materials Research Institute and Changwon Hanmaeum Hospital signed a business agreement to strengthen future convergence medical technology capabilities.

Changwon Hanmaeum Hospital quickly reviewed the principles and verification results of the conductive air purification module technology proposed by Materials Research Institute, and began verification testing to apply it to the hospital air conditioning system and objectively compare it with the air purification module used previously.

As a result of a demonstration test in which a conductive air purification module and a general air purification filter were installed in two air conditioners with the same specifications, and the fine dust removal efficiency and power consumption were measured and compared, it was confirmed that the general air purification filter removed about 40% of the fine dust, while the conductive air purification module removed more than 80%.

In addition, it was confirmed that while the general air purification module air conditioning system consumes about 44 kWh of electricity per day on average, the conductive air purification module air conditioning system consumes 33 kWh per day on average.

This means that when using a conductive air purification module compared to existing ones, the electricity cost generated through the operation of the air conditioning system can be reduced by approximately 25% or more. In addition, it is expected to be of great help in strengthening ESG management as the amount of greenhouse gases emitted into the atmosphere can also be reduced by the same amount of electricity saved.

Changwon Hanmaeum Hospital CEO Ha Chung-sik said, “If the existing air conditioner’s power consumption was around 4 million won per year, if the Airclicen model is applied, it will be around 3 million won per year. If around 60 units are installed, we can achieve an annual budget savings of around 60 million won.” He added, “Based on the results of this collaboration, Changwon Hanmaeum Hospital will continue to actively apply various cutting-edge technologies to the hospital system, and through this, we will take the lead in maintaining a pleasant and healthy indoor hospital environment and in protecting the global environment.”

Changwon Hanmaeum Hospital plans to continue the verification test of the conductive air purification module until June 2024. In addition, it announced that it plans to confirm the safety of application to the hospital building based on the results of more verification tests and then decide whether to apply it to the entire hospital air conditioning system.
