What Sihm Højtryk does

Sihm Højtryk A/S is a privately held Danish industrial company founded in 1991 by Kurt Sihm and headquartered in Esbjerg Ø, Denmark. The company designs, manufactures, distributes, and services high-pressure equipment spanning 100 to 7,000 bar, operating as both a wholesaler of international brands (Hammelmann, Dynajet, Aquajet Systems, Parker Hannifin, Resato, Perndorfer, Dynaset, HAKO/Oertzen, Bolondi, Reprotex, ENZ, Mosmatic, HiFlux, TST, TurtleSkin, Uhrig Quick-Lock) and a custom-engineering house under its own Aquatool® trademark. Core products include high-pressure cleaning units, pressure testing rigs, water jet cutting tables and pumps, hydro-demolition robots, tank-cleaning and no-dig pipe-repair systems, process pumps for oil & gas and Power-to-X (PtX), and a full accessories range (nozzles, fittings, hoses, valves, safety equipment). The company also operates a Parker Polyflex-certified hose fabrication workshop (up to 4,000 bar) including the only Parker FA35 BOP hose workshop certificate in Denmark.

The business operates a sales-led go-to-market with technically experienced staff selling engineered solutions rather than commodity equipment, supported by 24/7 phone availability, BOSIET-trained offshore service technicians, on-site calibration, and global reach through strategic agents. Revenue is generated across five streams: equipment sales (Aquatool custom builds and standard product lines), equipment rental (Resato pressure testing pumps and mobile high-pressure units), service and repair, training courses (online and hands-on), and water filtration system rentals. Pricing is quote-based for custom and project work, with published reference prices ranging from DKK 3,800 (entry-level cold-water cleaners) to DKK 575,000 (factory-new Dynajet trailer units) excluding VAT.

Sihm Højtryk serves five primary verticals: oil, gas and offshore energy (including wind and emerging PtX); maritime and shipbuilding; construction and municipal services; industrial surface treatment; and food and pharmaceutical. The customer base is enterprise-led for offshore, energy, and maritime accounts and government-led for municipal work, with SMB reach enabled through used-equipment sales, equipment rental, and a leasing partnership with Leasing Fyn. The company is ISO 9001:2015, ISO 14001, and QHSAS 18001 certified, holds AAA credit rating from DNB, and maintains ~14-16 employees with the current owner, Frank Sihm, leading the business following the 2004 generational transition.
