What Wigersma & Sikkema does

Wigersma & Sikkema B.V. is a Dutch privately held industrial manufacturer founded in 1921 and headquartered in Doesburg, Netherlands. The company develops, produces, and sells a specialized portfolio of gas measurement and pressure regulation equipment — including electronic volume conversion instruments (UNIGAS 300 series), gas pressure regulators (RS350S, RS300S, and Medenus spring-loaded units), secure diagnostic couplings (BDA 04), remote reading systems (UNICOM 300, UNILOG 300, ISC 230B), and the PLEXOR inspection system for testing gas pressure regulating stations — serving gas distribution utilities, industrial gas users, and emerging hydrogen infrastructure operators across Europe, Scandinavia, Central/Eastern Europe, and selected markets in Asia and South America. Products carry the full stack of European regulatory certifications (MID, PTB, ATEX Zone 0, DVGW, PED, KIWA) and the RS350S regulator plus PLEXOR couplings have been independently validated for 100% hydrogen service.

The company generates revenue through direct and distributor-channel hardware sales, with pricing on a quote basis and multi-year contract cadence. Go-to-market relies on a global network of 15+ exclusive and non-exclusive distributors covering Sweden, Norway, Denmark, Germany, Switzerland, Poland, Austria, Hungary, Serbia, Bulgaria, Croatia, Lithuania, Russia, Belarus, Kazakhstan, Singapore, China, and Argentina, supported by dedicated account management, technical telephone support, and remote/on-site training. The company operates a 11–50 employee organization with ISO 9001 and ISO 14001 certifications (TÜV Nord), and integrates its products with customer asset-management systems including SAP, IBM Maximo, K3V, EnVIstOr, and Autodesk AutoCAD Map 3D. Strategic emphasis is on quality, short delivery times, and positioning for the European energy transition to green gas and hydrogen.
