INDUSRIAL INDUSRIAL RANGE COMONENS FOR ENERGY SANG Fin-e HE -SARS EFFICIENCY SYSEM AENED BY ICI CALDAIE Fin-e is a system that increases the boiler efficiency: energy saving reduces environmental impact. Fin-e is an aluminum extrusions, with internal fins, inserted in the rear of the boilers smoke tubes in order to guarantee the complete contact between surfaces. While flue gas transmits thermal energy along the finned surfaces, its own temperature is reduced before it reaches the smokebox chamber and therefore it exits at the chimney at a very low temperature. BENEFIS: - performance increase to stars; - reduction of fuel consumption and CO emissions; - respect for the environment. SERCE: - installation of Fin-e System by ICI authorized assistant centre; - new certification. ICI CALDAIE SpA CAALOGUE
