DYPNF was established in 1999 and listed on KOSDAQ in 2009 as an engineering firm specializing in pneumatic conveying systems (PCS). Its core product uses air pressure to move powder materials horizontally and vertically for petrochemical, power generation, and fine chemical process industries.
As of 3Q2023, revenue mix was estimated at 48.89% PCS, 30.26% E&R (engineering and remodeling), 12.77% environmental business, and 7.99% mechanical conveying systems (MCS).
The company is described as the only domestic firm capable of implementing both high-pressure/low-speed and low-pressure/high-speed conveying methods, and is regarded as ranking third globally in the PCS market behind Coperion and Zeppelin.
It entered the secondary battery market in 2020 through an order to supply transport equipment for Cosmo New Materials' NCM cathode active material capacity expansion, and has since expanded into precursor materials and waste battery recycling.
In December 2025 it signed a KRW 58.4bn contract with Namhae Chemical Corporation for the Nakpo pier logistics facility improvement project, running through June 2030, while also executing a large EPC (engineering, procurement, construction) contract with Sambak LFT, a Lotte Chemical affiliate, to build a compound materials plant.
In the battery business, the company signed an investment MOU with Daegu Metropolitan City to build a used-battery recycling plant, broadening its footprint into waste battery and environmental fields.
This combination of traditional petrochemical and power plant EPC work with newer secondary battery and environmental businesses defines the company's portfolio structure.
