What Dopak® does

Dopak® is a global manufacturer of closed vent sampling systems and related accessories for liquids, gases, and liquefied gases, serving the chemical, petrochemical, refining, and offshore industries. The product portfolio centers on patented sampling hardware organized into product series (DPM, DPJ, DPT, HD, S23, S32-G, S32-LG) designed to enable safe representative sampling of toxic, dangerous, and volatile substances while reducing operator exposure and environmental emissions to virtually zero. Core offerings include Closed Sampling Systems, Sample Handling Systems, Spare Parts, Open Sampling, the Sampling Express quick-delivery program, and the Crane SAFE Sampling audit service offered in partnership with TSI. Products are built in-house using CNC machining centers and lathes, with ATEX compliance for hazardous-area applications.

Dopak operates as part of Crane Co.'s Instrumentation & Sampling portfolio, with wholly-owned entities Dovianus BV in Bergschenhoek, Netherlands (European headquarters) and Dopak PFT Corp. in Houston, Texas (North American headquarters), plus Crane Instrumentation and Sampling operations in China and India. Revenue is generated through direct sales from these offices and an extensive global distributor network covering 30+ countries across Africa, Asia, Australia/Oceania, Europe, the Middle East, and the Americas. Customers are predominantly large enterprise operators and EPC contractors, with documented deliveries to Shell (Iraq Majnoon, Prelude FLNG, SDA), BASF (Ludwigshafen TDI plant), Cameron Liquefaction, Total (Antwerp OPTARA), and Duslo.

The business model is project-based engineered-hardware sales, where systems are specified into customer plant designs during EPC construction and delivered in unit volumes ranging from dozens to over 150 per project. Pricing is custom-configured and not publicly disclosed. The company benefits from parent-company brand equity (Crane Co. operating since 1855), patented safety-critical designs, qualification into major LNG and offshore installations, and a multi-decade reference base across blue-chip energy and chemicals customers.
