For the installation of large equipment at a site, the traditional approach has been to appoint an EPC contractor with responsibility for the complete engineering, procurement, and construction project. Certain activities, including process design, building layout, and architectural concepts, may be handled internally, while specialized subcontractors complete the piping, electrical, and structural work.
However, as demand for electrification increases, attention is shifting toward how these systems are delivered, integrated, and operated.
Electrode boilers are increasingly being incorporated into larger projects managed by third-party contractors responsible for full system integration, rather than purchased as standalone equipment. Now, integrated turnkey solutions are also available from single-source providers that perform all the work in-house. These offerings include the boiler along with all ancillary equipment necessary for installation and may be constructed directly at the site or delivered as prefabricated units for rapid assembly.
These modular designs can reduce project time from months to just a few weeks while also reducing overall costs. By limiting on-site work, they avoid the complexity and expense of installing equipment in existing spaces crowded with piping and steel structures.
“All the steel structures for the building, concrete work, pipe assembly, electricity, and control systems—everything is included,” says Juha Mäntynen, Chief Executive Officer of CT Industrial Oy (CTI), a Finland-based CleanTech provider specializing in turnkey, zero-emission, high-efficiency energy systems, including high-voltage electrode boilers for industrial and district heating applications across 19 European countries.
Modern Electrode Boilers
Modern high-output electrode boilers are redefining how industrial facilities and district heating networks generate steam and hot water. Designed to operate using high-voltage electricity, today’s systems can deliver output capacities of up to 68 MW and steam pressures reaching 39 barg, placing them firmly in the range traditionally occupied by large fossil-fired boilers.
In many cases, the complete hot water or steam boiler system can be assembled in CTI’s facility as a single module similar in size to a shipping container. All piping connections, alignment verification, and functional testing are fully completed before the unit is transported.
These modular solutions are suitable for both steam and hot-water applications and can be implemented in either horizontal or vertical configurations with capacities typically reaching approximately 10 to 12 megawatts. For the electrode boilers, CTI partners with North America-based Acme Engineering, a manufacturer of industrial and commercial boilers, to provide high-voltage electrode boilers to the European market.
Mäntynen says Acme Engineering is unique in offering a horizontal hot water boiler design that is particularly well-suited for retrofit projects. Acme Engineering also offers vertical boilers including the jet boiler, capable of handling higher pressures with zero to 100 percent modulating capacity, and the immersed electrode boiler, which can be configured for either hot water or steam applications.
According to Mäntynen, in a recent project the complete boiler structure built around a horizontal unit from Acme Engineering that measured approximately 19 meters in length, 7.5 meters in width, and 6 meters in height.
For larger installations, the boiler system can be divided into multiple transportable sections that are shipped worldwide and require only minimal on-site assembly.
