Hydro-X

What Hydro-X does

Hydro-X A/S is a Danish chemical water treatment company headquartered in Hjallerup, Denmark, founded in 1940 (with product origins in the 1920s) and operating across more than 20 countries in Europe, Asia, and Africa. The company develops, produces, and supplies specialty chemical formulations for industrial steam boilers, district heating and central heating systems, industrial cooling water systems, and water softening and filtration. The core product portfolio comprises six proprietary chemical lines — Boilercompound (including E10 Super and E5 Special), Hydrotan, Hydrocor (corrosion protection), Hydroplex (hardness and scaling control), Hydrocid (biocide disinfection), and Uranin Tracer (district heating leak detection, in market leadership for over 30 years) — complemented by dosing equipment, water softening and filtration systems, and a pH-Controller. Products are manufactured in-house at Hjallerup (Denmark), Kobior (Poland), and Tianjin (China).

Hydro-X generates revenue from three streams: (1) one-time/recurring sales of water treatment chemicals (offered in 20L, 200L, and 700L pack sizes) to industrial and power-sector customers; (2) subscription-style service agreements, including scheduled yearly visits, on-demand service visits, day-to-day chemical delivery, and water sample analysis at an in-house laboratory staffed by a chemical engineer; and (3) equipment sales and rentals (water softeners, filtration systems, dosing equipment, pH-Controllers). Pricing is handled via direct consultation with custom multi-year service contracts; pricing is not publicly disclosed. The go-to-market relies on direct sales from Denmark supported by a 250+ worldwide sales-and-service network through subsidiaries and channel partners, with ISO 9001 Quality Management and DS/OHSAS 18001 certifications providing quality and safety differentiation. As of 1 November 2022, all Scandinavian sales and service operations were sold to Guldager A/S, which now serves as the primary channel for that region; the international subsidiary network otherwise remains intact.

Management oversight rests with a small Denmark-based team of approximately 14 staff (including key contacts Flemming Wittenberg in Finance, Administration and HR; Rasmus Sand in Sales and Equipment; and Henrik Jakobsen in Production and Warehouse), working alongside the international subsidiary and partner network. The legal entity is Hydro-X A/S, a privately held Danish public limited company with no publicly disclosed ownership, funding events, or revenue figures.
