1979

Succeeded in developing the foremost plate type heat type exchanger in Korea.

DHP was born in 1978 when Korea's industrialization had been boomed.
The late Mr. Song Gi-taek, former chairman or founder of the company, whose oil refinery business had been so flourishing but gave up suddenly due to unexpected incident had a motive to develop a plate-type heat exchanger because the late Mr. Lim Dae-hong, former chairman of Miwon Co., Ltd. who had a good friendship with him recommended it.
For the liquid sterilizer, one of the most important plants for Miwon which produced the seasoning product with the sterilizer at that time, Japan developed a plate-type heat exchanger from Europe and then they improved the productivity dramatically so the late chairman Mr. Lim who imported it found the real value of the equipment trying to use it for all production lines but since the cost was so high that he wanted to make it localized.

As a result of some trial and errors for about one year, the first plate-type heat exchanger was unveiled developed by the founder in 1975 when the founder was involved in replacing plate-type heat exchanger and maintenance work at the factory of Miwon Co., Ltd. as a staff of Miwon and afterwards he started his own business under the permission of the late chairman Mr. Lim of Miwon in 1978 setting up the company at Seo-myeon in Busan with the company name Daewon Heat Plate Ind. Co.
