These boilers are made in different capacities with high heat levels and different working pressures, and they are ideal and cost-effective for buildings and places that have problems with engine space. These boilers are made in the form of fire tubes with high quality sheets and tubes according to B.S855 and German DIN standards. The steels used for pressure parts are 17MN4 & A516 G70 and the pipes used are ST35.8. These types of boilers, in addition to having special strength and beauty, with the installation of two furnaces and the installation of heat transfer tubes vertically, have a high efficiency and thermal level.
