e-SG Electric Steam Generators

• No combustion means no atmospheric pollutant emissions: no nitrogen oxides (NOx), sulfur oxides (SOx), or carbon dioxide (CO₂)
• Precise control of steam pressure and temperature
• Instant start-up and rapid response to load changes
• High turn-down ratio

• Total conversion of electrical energy into heat, achieving near 100% efficiency
• Integration with flame boilers and industrial heat pumps via a dedicated load-splitting system
• Easy and low-maintenance operation

To ensure optimal performance, boiler feed water must have very low hardness and conductivity to minimize blow-down and heat loss.
Treatment can be performed using membrane technology or ion-exchange systems. Depending on the quality of the water source, specific pre-treatment may be required to achieve the correct parameters.

To protect the boiler and the system from corrosion, it is essential to remove dissolved gases such as CO₂ and O₂ from the feed water.
Different boiler water deaeration technologies are available: conventional deaerators with a tank and external oxygen stripping tower, or compact units where stripping occurs in a dedicated section within the same storage tank. Performance ranges from 7 to 20 ppb, depending on the unit installed.

Condensate Treatment

Recovering and purifying process steam condensate is a key step for reducing overall water consumption and improving energy efficiency by reusing the heat contained in the condensate.

Chemical Dosing

Chemical conditioning of boiler water is an additional treatment step carried out after the deaerator and before entering the boiler.

Using chemical conditioners ensures water meets system requirements, improves energy optimization of the steam generator + water treatment package, and helps reduce operational and disposal costs.
