Product variants at a glance
HDO-E und HWO-E
Electric steam boilers
Versions for:
- Steam
SCHNEIDER HDO-E – Electric steam boiler in the once-through design
Steam output up to 20 t/h - Hot water
SCHNEIDER HWO-E – Electric hot water generator in large-water-tube boiler design

The SCHNEIDER electric boilers of the HDO-E and HWO-E series are electrically heated steam and hot water generators designed to meet specific operational requirements. Their function and mode of operation are essentially the same as those of conventional steam or hot water generators of the large-water-tube design.
They are particularly used where conventional boilers are not suitable due to structural conditions, legal regulations, specific hygiene requirements, environmental considerations, or purely economic reasons.

WRK-HP-E
Horizontal with drum
Steam and hot water generators
- Steam capacity up to 20 tonnes per hour and 100 bar
learn more
The SCHNEIDER WRK-HP-E is an electrically powered single-drum water-tube steam boiler based on an internal natural circulation system. The WRK-HP-E is the electric alternative to a SCHNEIDER WRK or HPB (water-tube boiler) fuelled by liquid and/or gaseous fuels. It is the ideal solution for open steam-condensate circuits where the steam comes into direct contact with the product.
The WRK-HP-E converts electrical energy into heat using resistance heating elements, which require a sufficient low-voltage power supply (400 V / 690 V / up to 1000 V) for connection.
Areas of application
- Food and drink industry
- Oleochemistry, fat hydrolysis
- Deodorisation of edible oils and fats
- Distillation, fractionation, esterification
- Power-to-Heat
Benefits
- Compact design and self-supporting boiler construction
- Production of completely dry steam
- Ideal adaptability to the spatial conditions of the installation site
iNook-E
Electric natural circulation boiler
Steam generators for closed circuits
- Heating capacity up to 6.0 MW and 100 bar
learn more
The iNook-E is a vertically mounted electric steam generator designed specifically for closed steam-condensate circuits. It is positioned directly below the heat consumer (condenser) and is connected to it in a non-isolatable manner. The steam generated in the iNook-E serves as a heat transfer medium, which transfers its thermal energy to a process via condensation. The boiler and condenser are operated in a completely closed system according to the natural circulation principle.
The iNook-E is a natural circulation boiler and consists of several separate boiler evaporation elements that are fed via a common manifold (with a central condensate return pipe). The water-vapour mixture rising from the individual evaporation elements is collected in a common header and directed via a central steam connection towards the process-side heat exchanger.
The iNook-E converts electrical energy into heat using resistance heating elements, which require a sufficient low-voltage power supply (400 V / 690 V / up to 1000 V) for connection.
Areas of application
- Food and beverage industry
- Deodorisation of edible oils and fats
- Distillation, fractionation and esterification of a wide variety of substances
- Power-to-Heat
Benefits
- Membrane wall construction
- 100% smoke gas tightness between the flues – no leakage
- Highest possible efficiency compared to other designs
- Direct integration of the evaporator pipes into the manifolds (without reducers)
- No risk of heating surface overheating / flow interruptions
- Number and arrangement of steam discharge pipes
- Minimization of pressure losses in the boiler system
- Increase in water circulation rates
Key technical specifications
- Scope of services: project-dependent (multiple modules can be combined)
- Operating pressure: depends on the configuration
- Types: Horizontal, modular, electrically heated
Structure and operating principle
Electric boilers use electric heating elements to directly heat hot and superheated water and generate saturated steam. The modular design allows flexible adjustment of output.
