[INQ. NO. 2610M03] Kookje TNC Co., Ltd. recently introduced its integrated capabilities encompassing the design, construction, operation, and maintenance of natural refrigerant CO₂ systems (R-744), based on field experience gained from the actual construction and application of the first natural refrigerant CO₂ refrigeration system (R-744) in a large supermarket in Korea.
The solution is characterized by a combination of CO₂-specific equipment from global technology partners and system-integration technology tailored to domestic sites.
Centered on the CO₂ booster-based integrated compressor rack of Carrier Commercial Refrigeration (CCR), Kookje TNC introduced condensing units for convenience stores and small retail outlets, as well as Haier’s showcases. The integrated configuration was characterized by considerations for installation space and operational efficiency, and the company showcased its modulating ejector technology, which is a key technology for improving energy efficiency.
Kookje TNC unveiled its capabilities in design reflecting local climate and site conditions, integrated package construction, high-pressure safety and detection systems, and operational optimization. According to data from a Lotte Mart branch where the CO₂ system was constructed and installed by Kookje TNC in 2025, it demonstrated energy-saving effects of over 30% compared to the existing R-448A system.
Since its founding in 2001, Kookje TNC has built customer trust through accumulated experience and specialized expertise in refrigeration and cold storage systems.
“We have continued working to deliver the value customers need, from precise design, to reliable construction, systematic maintenance, technical consulting, commissioned training, and precision diagnostics. We are also expanding our business scope through the import and sale of unit coolers and showcases to provide broader solutions,” the company’s CEO remarked.
He added “We will remain a trusted partner that improves energy efficiency and reduces management costs through a responsible attitude and a steady commitment to technology. We will prepare for our customers’ future together while fulfilling our environmental and social responsibilities as a refrigeration specialist.”
