The history of Heco International

Henning Cornelius

The name Heco comes from our founder, Henning Cornelius. In 1959, he founded the company, and later that year, presented a new invention: the effective machine for renovating of the scraper rings for the piston rod stuffing boxes of the time. Back then, they featured scraper rings with a fixed scraping edge. It became the solution of the future for piston rod stuffing boxes for two-stroke diesel engines. Though piston rod stuffing boxes have been developed and improved several times in close cooperation with the leading designers, the basic principle is unchanged compared to the one Henning Cornelius patented 60 years ago in 1962.

Then to now

Heco International today is a result of the 1988 unification of Maskinfabrikken Heco, and Vejle Ringe & Magnetfiltre (founded in 1972), demonstrating our commitment to our global engagement. This was further validated with the establishment of Heco Mechanical Seals Technology Co. Ltd in Suzhou, China, close to the world’s largest engine builders. Becoming part of the G&O Maritime Group in 2015 has allowed our services to stretch further than ever before as a part of their propulsion management division.

Such a phenomenal pedigree only pushes us to maintain our position as the preferred and most reliable supplier of high-quality piston rod stuffing boxes and spare parts to engine builders and designers worldwide.
