After the first experiences in the manufacturing of evaporators, dated back to the seventies, FBR-Elpo, during the early nineties, started the tests and further industrial construction of a forced flow circulation evaporator. This evaporators, called Eco Energy, was designed with the precise aim to obtain remarkable energy and structural savings, in comparison with the traditional equipment with same capacities. The valuable peculiarities of this new product, can be summarized as follows: special position of the tube nests, that allows to use low capacity pumps and, consequently, lower installed power; high performance condensers; reduced overall dimensions. The control systems, resulting from the well-known aseptic equipment, is undisputed master of the field. In addition to this innovative product, FBR-Elpo manufactures a wide range of solutions for any exigencies of the market in the concentration field: from the evaporators at forced flow circulation, mixed circulation, falling film circulation, till the thin film and scraped surface evaporators.
