Precision due to welding in ideal position Thanks to horizontal welding with highly modern welding processes, a more homogeneous structure, a deeper root penetration and notchfree welding s urfaces are achieved. Use of welding robots Semi-automatic and fully automatic welding robots are used for consistently high quality on highlystressed welding seams. Optimum design Thanks to an ideal ratio between water content and steam c hamber, Bosch boilers are optimised in their design for rapid heating and a high level of steam quality. Ideal temperature distribution and release of vapour bubbles enables...

Bosch electric steam boiler ELSB Sustainable steam with green electricity The steam chamber on the ELSB produces high quality steam and has low residual steam moisture. Thanks to its variable output, the thyristor circuit of the control achieves an extremely high level of efficiency across the entire load range. Furthermore, the output can be automatically adjusted to your requirements or to available surpluses in the self-generated electricity. The ELSB electrical steam boiler does not emit any flue gas. Neither the chimney, the flue gas aftertreatment components nor the infrastructure for the...

Design The durable ELSB electric steam boiler offers a high steam space and proven Bosch quality with an efficiency of up to 99.6%. The heating bundle and boiler are optimally matched to each other. The integrated heating bundle has backup elements for many years of operation and, thanks to thyristor technology, offers continuous boiler control from 0-100%. As there is no combustion, the installation effort is reduced. No flue gas system is required and thus no chimney in the case of a purely electric steam supply. Fuel supply and storage are also not required. The safety equipment includes safety...

Ultra-compact steam boiler, available in a wide range of output sizes. Enables future-proof low emissions and a high efficiency level. The ideal solution for food and beverage industries, manufacturing industries, hospitals, laundries and hotels. The CSB achieves a high level of efficiency thanks to its helical heat exchanger tubes and integrated economizer. In addition, the sophisticated insulation concept and Bosch multi-compound insulation ensure minimal radiation losses. ► Innovative boiler design and efficiency modules for high energy efficiency and fuel savings ► Optional condensing heat...

14 | Steam boilers Steam boilers | 15 14 | Steam boilers Steam boilers | 15 The steam-drying unit and the generously dimensioned steam chamber in the Universal CSB design guarantee a high level of steam quality that suits your processes. The high-quality production of the entire boiler body using the latest in welding robots allows for a particularly high level of robustness and durability. Thanks to the special helical heat exchanger tubes, the heat exchange per m2 of heating surface is improved significantly. The use of inserts in the exhaust system is not required, which makes cleaning significantly...

The product designation U-MB stands for “UNIVERSAL Modular Boiler” (three-pass steam boiler in modular design). The U-MB type consists of several modules, which fulfil your individual requirements perfectly. Typical application areas are the food and beverage industry, laundry and cleaning businesses, as well as smaller industrial companies. The boiler components are configured with a focus on low emissions, high steam quality and optimum energy efficiency. ► High level of efficiency due to the integrated economizer ► Maximisation of efficiency thanks to modular heat recovery modules User-friendly...

18 | Steam boilers Steam boilers | 19 18 | Steam boilers Steam boilers | 19 The steam boiler U-MB is designed as a three-pass flame tube/smoke tube boiler. It consists of several modules, namely the heat generating section in three-pass design, the steam chamber on top of this, and an integrated economizer. Thanks to its three-pass design, there is no requirement for flow components in the smoke tubes. The heat generating section of the U-MB is based on the UNIMAT boiler design - proven for decades and many thousands of times in practice. The generously sized flame tube geometry enables an efficient...

UNIVERSAL steam boiler UL-S/UL-SX High level of efficiency for reduced operating costs The boiler type UNIVERSAL UL-S sets new standards in your process heat supply. Highly efficient and reliable in use in food and beverage industries, in manufacturing industries and in municipal facilities. You can save up to 7% with the integrated economizer for waste heat recovery. Other optional modules, such as continuous feed water control for a constant water level in the boiler, speed-controlled burner fans for electricity reduction and O2/CO controls for optimum combustion quality, achieve an even higher...
