Demaco

What Demaco does

Demaco Holland B.V. is a Dutch cryogenic infrastructure specialist providing consultancy, design, engineering, production, testing, installation, and maintenance services for vacuum-insulated cryogenic systems. The company builds custom Vacuum Insulated Transfer Lines (VIP) and a portfolio of complementary cryogenic components — including degassers, phase separators, subcoolers, automatic gas vents, valve boxes, cryogenic valves, level sensors, filling systems, and LH2 loading bays/arms — for transporting and storing liquefied gases at extreme temperatures (LN2 at -196°C, LOX at -183°C, LNG at -162°C, LH2 at -253°C, LHe at -269°C). Its proprietary VIP technology combines high-vacuum insulation with multi-layer aluminum foil and glass paper radiation barriers, delivering up to 15x better insulation than conventional materials such as PIR/PUR, Foamglas, Armaflex, Perlite, and Misselon.

Demaco serves a diversified enterprise customer base spanning industrial gas producers (Air Products, Linde), scientific research institutes (CERN, DESY, Fermilab, SLAC, ESS, GSI FAIR, ITER-India, ETpathfinder), space agencies (ESA ESTEC, ISRO), pharmaceutical and medical clients (Merck, MSD, Sheba Medical Center), food industry players (FrieslandCampina), industrial users (Tata Steel/Corus, Equinor Snøhvit), and EPC contractors. Revenue is generated primarily through custom-engineered project contracts — with delivery cycles of 4-12 weeks for systems and 3-12 months for plant-scale installations — complemented by standard vacuum component sales through the demaco-vacuum.com e-commerce webshop. As of July 18, 2024, Demaco operates as part of OPW Clean Energy Solutions (a Dover Corporation company), with international agents in France, Spain, China, and Malaysia supporting global project delivery and installations across Europe, Asia, North America, and the Middle East.

Revenue model

1. Cryogenic Infrastructure Projects: Demaco designs, engineers, manufactures, tests, and installs custom vacuum insulated cryogenic infrastructure systems. Projects include design, production, installation, and documentation (data book and manual). Revenue is generated through project-based contracts for piping, systems, and complete plant installations. Typical delivery times for systems range from 4 to 12 weeks; larger plant projects span 3 months to a year. Projects are delivered with full certification and compliance documentation per EN 13480, ASME, IGC, and TRCU standards.
2. Vacuum Technology Components Sales: Sale of vacuum components, pumps, pressure gauges, mass spectrometers, leak detection devices, flanges, valves, and filters through the dedicated demaco-vacuum.com e-commerce webshop. Also includes sputter systems and ultra-high vacuum products built to customer specifications.
3. Cryogenic Products and Accessories: Sales of proprietary cryogenic products including degassers, phase separators, subcoolers, gas vents, filling systems, valve boxes, de-icing units, cryogenic valves, level sensors/controllers, and cooling trays. These are sold both as standalone components and as part of larger infrastructure projects.

Core offering

Demaco designs, engineers, manufactures, tests, installs, and maintains custom vacuum insulated cryogenic infrastructure for transporting and storing liquid gases such as liquid nitrogen, oxygen, LNG, liquid hydrogen, and liquid helium. The company's core platform is its proprietary Vacuum Insulated Transfer Lines (VIP) technology, supplemented by cryogenic accessories, filling systems, valve boxes, LH2 loading equipment, and application-specific cooling trays, sold primarily as project-based B2B contracts to industrial gas producers, research institutes, space agencies, and EPC contractors.

Product overview

Demaco is a cryogenic infrastructure specialist offering vacuum-insulated solutions for transporting and storing liquid gases. The product portfolio centers on Vacuum Insulated Transfer Lines (VIP) as the core platform technology, complemented by accessory components (Gas Vent, Degasser, Phase Separator, Subcooler, De-Icing Unit), control instrumentation (Level Sensor/Controller), and valves. The company provides specialized systems including Filling Systems and Multiple Transfer Lines (MTL), as well as application-specific products like Cryogenic Cooling Trays for food and automotive industries. For liquid hydrogen applications, Demaco offers LH2-specific VIP transfer lines, Loading Bays for trucks, and Loading Arms for ships. All products utilize high-vacuum insulation technology to maintain extreme cold temperatures and minimize boil-off gas during liquid gas handling.
