Reactors for the future

A strong partner for the chemical industry worldwide

DWE® has been constructing reactors and pressure vessels of large wall thickness for the chemical industry, for refineries, power plants and similar industrial plants. Over the years, we have acquired the best expertise in the field. We design in strict compliance with your requirements.

Our years of experience in reactors construction give us the highest level of expertise. The tubular reactors in operation all over the world have made us into a trusted partner in the industry. We pride ourselves on our strong customer relationships. Our careful handling of large numbers of tubes, tube-to-tube sheet welding as well as our zero-tolerance quality control have proven to be a strong 

foundation for our business. We believe innovation is a constant process and also conduct technical research into welding and heat treatment.

Among others, our reactors are used in the increasingly important production of liquid hydrocarbons from natural gas, biomass or coal. Known as GTL, BTL or CTL processes, they require robust and durable fluidized-bed tubular reactors. These reactors are also used for the production of methanol and ethylene oxide or for methanation. 

A custom-made reactor for your business

Each business is different, which is why we take great care to offer individualized reactors to all of our clients in the chemical, oil and gas and petrochemical sectors. Operating with gas, oil boiling or pressurized water for various applications, our reactors are made from high-grade materials such as carbon steel, nickel alloy, low- and high-alloy steel including vanadium-reinforced chrome steel and stainless steel. They are clad in special materials such as zirconium, guaranteeing you a long service life and extreme hardiness.

We fabricate our reactors in-house and ship directly from our own port; the logistics of transporting these frequently very large pieces of equipment are no trouble to us. We do offer sector design if your infrastructure requires it.
