HDO-E und HWO-E
Electric steam boilers
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 used in particular in situations where conventional boilers are not an option due to structural constraints, legal requirements, hygiene regulations, environmental considerations or purely commercial reasons.
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
Heat output up to 10 MW
Benefits
- Compact design
- Low maintenance
- Minimising external (investment) costs
- Clean operating conditions, hygiene benefits
- Favourable ATEX classification
Areas of application
- Chemical and pharmaceutical industry
- Hospitals
- Food & Beverage Industry
- Power-to-heat applications (P2H)
- Standby safety boiler
HWO-E module and WO-E module
Modular electric instantaneous water heater
The SCHNEIDER instantaneous water heaters in the HWO-E-Modul and WO-E-Modul series are electrically heated water heaters designed for general heating and domestic hot water supply.
By using standardised assemblies, flexible modules can be configured to provide the required heating output for any application. As these functional assemblies are largely pre-assembled, on-site connection to existing pipework takes very little time.
Versions for:
- Hot water
SCHNEIDER HWO-E module – electric instantaneous water heater
Heat output up to 10 MW Hot water
SCHNEIDER WO-E module – electric instantaneous water heater
Heat output up to 10 MW
Benefits
- Compact design
- Low maintenance
- Easy installation thanks to the modular design
- Minimisation of external (capital) costs
- Dlean operating conditions, hygiene benefits
- Favourable ATEX classification
Areas of application
- Power-to-heat applications (P2H)
- Balancing power applications
- Local and district heating
WRK-HP-E
Horizontal with drum
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.
In the WRK-HP-E, electrical energy is converted into heat using resistance heating elements, which require a suitable low-voltage supply (400 V / 690 V / up to 1000 V) for connection.
Steam and hot water generators
- Steam capacity up to 20 tonnes per hour and 100 bar
Benefits
- Compact design and self-supporting boiler construction
- Production of completely dry steam
- Ideal adaptability to the spatial conditions of the installation site
Areas of application
- Food and drink industry
- Oleochemistry, fat hydrolysis
- Deodorisation of edible oils and fats
- Distillation, fractionation, esterification
- Power-to-Heat
iNook-E
Electric natural circulation boiler
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.
In the iNook-E, electrical energy is converted into heat using resistance heating elements, which require a suitable low-voltage supply (400 V / 690 V / up to 1000 V) for connection.
Steam generators for closed circuits
- Heat output up to 6.0 MW and 100 bar
Benefits
