1 RL EN steam boilers RL 1/10

2 RL with two pumps ATTSU steam boilers series RL are the result of a long tradition in the boiler manufacturing bringing together simplicity of design and energy efficiency in an extremely robust and reliable equipment. Three-pass steam boilers with totally water cooled reverse flame furnace of high energy efficiency, low-level contamination and low-cost maintenance. In ATTSU we take care of every single detail from design, construction and finishes of our products which are remarkable in its sector by its safety, reliability and easy handling and access. Different cross-sections of RL model show the design of an ATTSU boiler which is known to be a key reference in the firetube boilers evolution. 2/10

3 Standard RL 300 (one pump and right-side control RL 600 (two pumps and left-side control panel) RL 2000 (two pumps and left-side control panel) RL steam boilers are manufactured in a range of steam rates from 50 to 0 kilos per hours and standard pressure up to 16 barg and are suitable for a great variety of industrial applications: Chemical Industry Food-processing industry Paper industry Pharmaceutical industry Solar thermal power plants Textile industry As well as a multitude of industrial processes: Air moistening in fermentation processes Curing of concrete in civil works Soil steaming, Steam turbine sealing Sterilization of surgical instruments Truck mounted RL 600 for outdoor operation To this purpose ATTSU steam boilers are available in many varied forms and in some cases, in order to avoid the construction of a suitable boiler house, they can be supplied in a containerized boiler room for an outdoor operation, fully installed and ready for operation and thus avoid any delay for civil works. In the same way, although they are designed and constructed in conformity with the German code TRD and the European Directive 97/23/EC, they can be designed according to ASME, BS, DNV, GOST, JIS and others.
