Since our founding in 2000, we have grown into a specialist in gas separation, gas purification, and gas engineering through continuous patents, certifications, and factory expansion.
ASPE originally began as an industrial gas engineering company, founded as O2 N2 Gas Engineering Co., Ltd. in August 2000. It was renamed to KGL Co., Ltd. in 2001, and later to ASPE Inc. in 2011.
The office relocated to Anyang in 2011, and the factory was expanded and relocated to Chungju (headquarters) in June 2012.
ASPE has registered numerous patents, including the O2 Supplying Equipment (2002), Top-manifold of O2 Generation Equipment (2004), VPSA type oxygen generator (2014), CO2 removal device (2014) and the simultaneous hydrogen/CO2 separation method (2021).
ASPE entered the medical field in 2004, obtaining ISO 13485 and ISO 14001 certification for its medical oxygen generator from TUV.
ASPE received the Export Tower Award (USD 1 Million Tower) on Trade Day in December 2021.
ASPE obtained ISO 45001 certification in April 2022, and completed KGS certified special equipment manufacturer registration (pressure vessels, heat exchangers) in July of the same year. ASME "U", "PP" stamps were renewed in 2026.
