2 | Quality, precision and a sense of responsibility Driving force for more than 150 years Bosch Industrial Boilers has been the leader in thermal systems and system solutions for more than 150 years. Trendsetting innovations and the consequent development of our products are the basis for outstanding efficiency and sustainability. More than 115,000 boiler systems delivered into more than 140 countries is proof of the high quality and reliability of our industrial boilers. Brand switch: Loos is now Bosch Company anniversary: 150 years Industrial boilers Loos becomes part of the Bosch group...

Quality, precision and a sense of responsibility | 3 Certificates prove high quality standards Numerous certificates and licences for our products in more than 140 countries all over the world are testament to the high quality and production standards of Bosch Industriekessel. All Bosch boilers and boiler house components conform to respective European guidelines for CE-labelling, especially the Pressure or Gas Equipment Directive based on technical standards (e.g. TRD, AD 2000 and EN norms such as EN 12953). The majority of our products and components are in conformity with the...

4 | Quality, precision and a sense of responsibility Optimised design for modern steam supply Modern steam boilers do not only have to work efficiently, they also have to manage dynamic pressure demands with a consistently high steam quality. When it comes to dynamics, water content and steam space are the factors most often taken into consideration, although other factors are physically more relevant. Far more crucial for the power reserve and the dynamics with consistently high steam quality are the water quality, the control quality and the height of steam space. Bad water quality leads...

Quality, precision and a sense of responsibility | 5 For Bosch’s industrial boilers (formerly Loos) the construction principle has been developed further and the use of stud bolts has been discontinued. The flame tube is fixed at both ends of the boiler body and occurring tensions can be passed on via diagonal stays (corner anchors). To prevent additional radiation of heat, the boiler’s inspection door is filled in with a special Bosch composite material with extremely high insulation qualities. It is designed to be maintenancefree during the entire service life when commissioned and...

Quality, precision and a sense of responsibility | 11 Higher quality through industry leading quality assurance methods Quality control by X-ray is part of our boiler production process. Our constantly high welding quality is confirmed on around 25,000 developed films per year. Our trained staff can check, evaluate and document weldseams at any time during operation. Going beyond the standard quality requirements up to 100 percent of a boiler’s weldseams are X-rayed. This also includes even our biggest boilers. In addition, we conduct ultrasonic tests, dye penetrant tests, magnetic particle...
