Cost- and energy-efficient heat production
Immersed electrode boilers are ideal for applications such as district heating plants, building heating, and industrial processes that require hot water or steam.
CTI has chosen ACME’s technology – a pioneer in high-voltage electric boilers – as the foundation for its boiler systems. The boilers are CE-certified and designed in compliance with the Pressure Equipment Directive (PED).
Our Immersed boilers convert virtually all supplied electricity into heat. Energy losses are minimal, making the solution highly energy-efficient. Power output is adjusted simply by changing the exposed surface area between the electrodes and the counter-electrode, by raising a protective shield around the electrodes. Immersed boilers are suitable for producing both hot water and medium-pressure steam, delivering efficient heat across a control range of approximately 7–100 %.
Juha MäntynenVice President, CTIThe Immersed-type boiler has a simple construction with few maintenance points. The ability to start up hot in under a minute and cold in just over half an hour is a major advantage for the customer.
One solution, many benefits
Extremely high efficiency: The Immersed boiler converts virtually all supplied electricity into heat. Energy losses are minimal, making the boiler highly energy-efficient.
Fast start-up: The boiler reaches full output quickly (hot start in about one minute and cold start in around 35 minutes), providing flexibility for varying energy demands.
Simple maintenance: The boiler has few moving parts, and water itself acts as the resistor. It only requires softened water and does not need expensive water treatment, reducing both investment costs and maintenance needs. Electrode lifespan aprpox. 4–5 years.
Safety and environmental friendliness: Since there is no combustion and no fuel involved, the boiler operates quietly and produces no emissions. Water chemistry requirements are minimal – typically, softened portable water is sufficient. The boiler's electrical grounding ensures safe operation in all conditions.
The Immersed-type boiler is fast, reliable, and environmentally friendly.
