Production and services for
vessels, tanks and equipment
Bilfinger looks back on decades of experience in the manufacturing field. Flexible, reliable and clearly focused on the customer, we are a competent and efficient partner in international plant engineering. With our extensively equipped workshops and flexible working hours, we can ensure our customers receive customized products of the highest quality.
Prefabrication includes the manufacture of piping spools and assemblies for complete industrial and power plants throughout the world.
We offer our customers a comprehensive service package along the entire value chain from design and production to maintenance & repair for tanks, boilers, vessels, heat accumulators and related equipment, such as filter separators, heat exchangers, process vessels, burners, scrapper traps, storage vessels and general pressure vessels. Being your equipment partner we ensure smooth operation, increased efficiency and reliability of your static equipment.
- Boilers
Bilfinger offers comprehensive services for industrial boilers and e-boilers, including inspection, overhaul, repair, and upgrades. As boiler OEM, we provide various types of boilers, such as conventional, electric and hybrid boilers. We are also your implementation partner for Zeta E-boilers in the Netherlands, Belgium and the UK.
With more than 155 years of experience, Bilfinger ensures reliable steam production with minimal environmental impact regarding CO2 emissions and fossil energy use. We also offer innovative technologies like hydrogen steam boilers and pyrolysis boilers and are your supplier for high-quality boiler equipment, boiler parts and spare parts.
- Deaerators
Deaerators are crucial in preventing corrosion in boiler systems by removing oxygen from the feedwater. Bilfinger offers advanced, patented spray-type deaerators that are more sustainable and cost-effective. They require no oxygen-absorbing chemicals and reduce steam loss by 90%.
Retrofitting existing tray-type deaerators with Bilfinger's spray-type components can significantly enhance performance, lower environmental impact, and reduce noise levels. Thanks to improved efficiency and extended equipment life, this retrofit typically yields a payback period of less than three years.
- Steam accumulators
Steam accumulators are crucial for managing steam demand and production fluctuations and serve as a strategic steam reserve. They help to lower your CO2 footprint and reduce fossil fuel consumption.
As OEM our standard steam accumulators can be manufactured up to 32 meters in length and 4.8 meters in diameter, storing up to 10-15 tons of steam per charge. Larger sizes and capacities are also available upon request. The response times for steam accumulators are typically about 2 seconds for initial response and 20 seconds for full flow during charging or discharging.
- Burners
Burners are essential in modern energy production, designed to minimize harmful emissions, enhance reliability, and allow flexible fuel use. Designing and implementing combustion technology often requires tailored solutions. At Bilfinger, we leverage over 100 years of experience in burner and boiler production. Our team of experts is ready to develop the optimal combustion solution to meet your specific needs. This includes converting existing boilers from liquid fuel to natural gas or hydrogen, and installing burners capable of handling multiple fuel streams

Enamel coatings in chemical and pharmaceutical containers are optimized for a wide pH spectrum in terms of thermal shock resistance, impact strength and, above all, corrosion resistance. However, to achieve this, the surface must be 100% "pore-free", i.e. the enamel coating must be completely free of defects. This is where we come in.
For your projects that require a certain degree of sensitivity because, for example, the pharmaceutical standard is desired or a certain surface finish is required, we are your competent partner for repairs and new fabrications.
Together with our customers, we develop individual solutions and offer expert advice. From the specification, the calculation and the design performance, to the documentation of the product, you benefit from our many years of experience.
