What CT Industrial does

CT Industrial Oy (CTI), founded in 2008 and headquartered in Haapavesi, Finland, is a privately held engineering and project-delivery firm focused on industrial and district-heating energy solutions. Its core technology is high-voltage electrode boiler systems (Immersed-type and Jet-type configurations, producing hot water, medium-pressure steam, and up to 40 bar industrial steam) supplied under an exclusive European partnership with North America-based ACME Engineering. Around this core, CTI offers four solution pillars: Reshape Energy (new electrode boilers and superheaters), Reform Energy (retrofit of existing fossil-fired boilers to biofuels and milling equipment), Restore Energy (BESS battery storage and FinGen diesel/gas backup generators), and Repair & Maintain (lifecycle services, spare parts, ATEX-classified maintenance, and 24/7 support from a Finland-based warehouse serving Northern Europe).

CTI serves district heating utilities and industrial process companies (food processing, dairy, water treatment) across 19 European countries. The business model is turnkey project delivery with approximately 70% of work executed by CTI's own personnel — including roughly 35 in-house fitters and welders plus specialised engineers — combined with a project-based revenue stream and a smaller recurring revenue base from spare parts, maintenance agreements, and ATEX services. The company is founder-controlled (Mikko Lehtonen as owner/Chairman), reported €13M in revenue with around 30 employees, and transitioned leadership in October 2025 with Juha Mäntynen appointed CEO. Notable reference customers include Helen (Helsinki), Porvoon Energia, Loiste Lämpö, Seinäjoen Energia, Valio Haapavesi, and Avena Kantvik Oy.

Core offering

CT Industrial Oy (CTI) designs, manufactures, and delivers turnkey energy infrastructure equipment for industrial and district heating customers, including high-voltage electrode boilers (Immersed-type and Jet-type), BESS battery energy storage systems, diesel and gas backup generators (FinGen), and biofuel retrofit/milling solutions for converting existing fossil-fuel plants. The company provides complete lifecycle services — from design and factory prefabrication through installation, commissioning, spare parts supply, and 24/7 maintenance — across Northern Europe.

Product overview

CT Industrial (CTI) is a Finnish energy and process technology company that offers comprehensive energy solutions organized into four main service areas: Reshape Energy (new electrode boiler systems), Reform Energy (retrofit and modernization), Restore Energy (energy storage and backup power), and Repair & Maintain (lifecycle services). The core technology portfolio centers on ACME Engineering-based electrode boilers offered in Immersed-type and Jet-type configurations, with Superheaters as supplementary equipment. BESS battery systems and FinGen backup generators provide energy storage and power reliability. Retrofit solutions enable conversion of existing fossil fuel plants to biofuels, supported by milling solutions for fuel processing. Sidestream solutions address circular economy and waste heat recovery. Turnkey delivery approach emphasizes approximately 70% in-house execution with projects delivered across more than ten European countries.

Functional benefit

Products and services

• Immersed-type electrode boilers High-voltage electric boilers with electrodes permanently submerged in water for district heating, building heating, and industrial processes. Converts virtually all supplied electricity into heat with minimal losses, suitable for hot water and medium-pressure steam production with a control range of approximately 7–100%.
• Jet-type electrode boilers Electrode boilers specifically designed for flexible steam production with water pumped through a nozzle unit onto electrodes, featuring 0–100% control range with fully stepless modulation. Produces high-pressure steam up to 40 bar, suitable for industrial process steam and district heating applications.
• BESS (Battery Energy Storage Solutions) Battery systems enabling electricity storage during low-price periods for use during high-price or peak demand times. Balances grid load and enables more efficient use of renewable energy, suitable for frequency reserve markets with modular and scalable configurations for industrial and utility-scale applications.
• FinGen backup generators Diesel and gas-powered backup power solutions that generate electricity locally when the national grid is unavailable. Designed for critical situations in hospitals, production facilities, and municipal heating plants, with automatic startup during power outages and hybrid system capability with batteries and electric boilers.
• Retrofit solutions Technological upgrades of existing plants enabling conversion from fossil fuels (oil, natural gas) to biofuels such as pellet dust, bio-oil, or biogas. Includes new burner, milling solutions, feed system, and automation upgrades, modernizing old boilers and energy systems without requiring full new investments.
• Milling solutions Fuel milling technology for pellet dust and other biofuels, including in-house mill delivery, fuel adaptability for various fuels (wood pellets, bio-dust, natural gas replacements), and integration into existing plants or new installations for efficient combustion.
• Sidestream solutions Solutions integrating industrial and heating plant sidestreams into a sustainable energy economy, including waste heat recovery, energy reuse with electric boilers and batteries, and system integration for hybrid models.
• Repair & Maintain services Comprehensive lifecycle services including spare parts from Finland-based warehouse, 24/7 technical service, repair and modernization for electrode boilers, grinding equipment, backup generators, and ATEX-classified equipment across Northern Europe.

Quantifiable outcome

• Electrode boiler payback under favorable conditions can be achieved within a year or less. Average price for reserve market electricity consumption was 3,000 euros per megawatt-hour. A 50 MW boiler operating one hour could earn approximately 150,000 euros.
