HARFKO 2026 to Unveil its New Lineup of Innovations

September 29, 2026 by Leave a Comment
https://korean-machinery.com///inquiry

Introducing a wide range of HVAC products that have evolved further through convergence with the latest information and communication technology (ICT)

The 18th Korea International Heating, Air-Conditioning, Refrigeration and Fluid Exhibition (HARFKO 2026) will be held for three days from October 21 to 23, 2026, at KINTEX 1 nearby Seoul — under the slogan ‘HVAC&R Innovation Led by Smart Technology: The Future of Heating, Air-Conditioning, Refrigeration and Fluid Completed by AI and IoT.’

Hosted by the Ministry of Trade, Industry and Energy (MOTIE) and organized by the Korea Refrigeration and Air Conditioning Industry Association (KRAIA), HARFKO 2026 is Korea’s most representative HVAC&R exhibition. As an exhibition that has obtained the ‘International Certified Exhibition+’ designation from MOTIE, approximately 230 companies from 23 countries, including Korea, China, Japan, Canada, the United States, and Italy, are scheduled to participate across 1,000 booths. A total of about 24,000 visitors are expected to visit the exhibition.

Riding the wave of smart technology currently sweeping through the HVAC industry, this exhibition will introduce a wide range of HVAC products that have evolved further through convergence with the latest information and communication technology (ICT) — such as Artificial Intelligence (AI), the Internet of Things (IoT), and big data — to match the exhibition theme.
The main exhibits will feature a wide range of future-oriented, innovative products incorporating smart technology across the entire field of refrigeration, freezing, and air conditioning — including refrigerant compressors, air conditioners, refrigeration and freezing equipment, HVAC components, cooling towers, work tools, control and measurement instruments, heating equipment, air equipment, facility materials, I.A.Q, and cleanrooms.

HARFKO 2026 to become a festival ground where industry, technology, and culture come together
A spokesperson for KRAIA explained, “We intend to showcase a future-oriented and innovative image of the HVAC industry to visitors through the excellent HVAC products from around the world that will be unveiled at this exhibition,” adding “Participation in the exhibition will provide a valuable opportunity to discover new business partners, enhance brand awareness and credibility, and gather insights for future vision and competitiveness — in order to cope with the rapidly changing tech landscape.”
During the exhibition, various side events will be presented, including an opening ceremony and awards for contributors to the development of the HVAC industry; an international symposium on new technologies, new refrigerants, and policies; export consultations; HARFKO academic lectures; and presentations on new technologies and products by participating companies.
HARFKO 2026 is thus expected to become a festival ground where industry, technology, and culture come together.

AI-based Resource Sorting Robot

August 26, 2026 by Leave a Comment
https://korean-machinery.com///inquiry

[INQ. NO. 2608M12] Aetech Co., Ltd. has come up with an innovative method to resolve labor shortages in resource-recycling operations by deploying AI-based robots.
Aetech Co., Ltd. participated in NextRise 2026, the largest startup fair in Asia, held at COEX in Seoul from June 18 to 19, and showcased ATRON, an AI-based resource-sorting robot.
Regarding ATRON, which operates based on 5.5 million data points collected from 24 locations nationwide, an Aetech spokesperson explained, “It demonstrates 99.3% accuracy and processes up to 96 pieces per minute, and sorts a total of nine types of sortable waste, including PET and PP.”

Composed mainly of a vision box and a robotic arm, ATRON recognizes the various types of waste by using sensors mounted on the vision box, and the robotic arm performs the task of sorting the waste into precise locations based on the recognized types.
Aetech developed ATRON based on deep learning to enable it to perform these tasks, ranging from waste-location detection and classification, to plastic component analysis, object- tracking on conveyors, and statistical analysis of waste data.
According to Aetech, ATRON has increased sorting speed by up to 240% and reduced working time by 126%. This has therefore resulted in a 279% reduction in sorting costs and a decrease of 860 kg in daily carbon emissions.
“Working at recycling sorting facilities is perceived as a ‘3D job’ (dirty, dangerous, and difficult), leading to severe labor shortages; however, ATRON can help resolve this issue. Currently, about 35 units have been sold domestically, and we plan to proceed with exports to Japan in the second half of the year,” remarked the company spokesperson.
Aetech’s various AI and robotics-based resource-recycling solutions are being manufactured to increase resource-recovery rates by more than double compared to the rates of the existing waste-treatment industry.
As the quality of recyclables improves and the amount of waste incinerated or landfilled decreases due to the company’s products with improved sorting accuracy, it is expected to contribute to promoting the circular economy by reducing waste-treatment costs and carbon emissions.
