Our story

Sihm Højtryk A/S was established on April 1, 1991 in Kurt Sihm’s garage, as a one-man company. The company has continuously evolved from selling conventional high-pressure equipment to also providing advanced industrial customized solutions. A generational change in 2004 also resulted in a decision to target sales more actively towards the offshore sector. This proved to be a smart decision, and we now have customized high-pressure units located all over the world.

An icrease in demand for a more sustainable production and a desire for a green transition led Sihm Højtryk to look at how we could contribute. As it turned out, we did not have to look far, as it turned out that many of the products already in our product program are suitable for this, including high-pressure pumps.

Sihm Højtryk A/S currently employs approx. 14-16 people who design, build and service high-pressure systems of up to 7000 bar used for e.g. surface treatment, pressure testing and water jet cutting. We act as agent and service center for some of the world’s leading brands.

We are currently located in Esbjerg Ø in a newly established industrial area right next to the E20 highway (exit 75).
