3 LTG Tangential Fans - an advantage for optimum heating, cooling, drying, blasting Many production processes require a linear extended and absolutely even distribution of air or other gases to the working area. Because of their special design, tangential fans meet this requirements in the best possible way. The rigid design and the use of high quality materials secure a long service life. By the working principle, that does away with additional baffles and vanes and the space saving design, the use of tangential fans is very economic. Flow principle The air intake of tangential fans takes place over the whole length of the outer impeller periphery. The air then flows into the impeller interior where it is reversed and accelerated by the vortex caused by the impeller rotation. Finally the air is distributed at the discharge side over the whole impeller length. In this way the air flows through the impeller first from outside to inside and then from inside to outside. The impeller is a cylindrical cage of forward curved impeller blades with two or more supporting discs. The vortex separates suction side and discharge side at the narrowest line between impeller and vortex inducer and causes the flow pattern together with the scroll. The Innovation Company Advantages Uniform air flow over the entire fan width. Additional baffles, plenums and guide vanes are not required. Space saving due to a 90 airflow deflection. The fan width can be exactly matched to the machine width. The air flow pattern does not change with wider machines (simplifies design and drawings of modular systems). Works equally well in any arrangement (right hand drive or left hand drive available). Low noise operation due to aerodynamic design based on 25 years experience. Impeller bearings out of air flow. Many bolt -on options. Fields of application Examples of some fields of application are: Bakeries, drying systems, industrial ovens, packaging industry, cooling and refrigeration systems, department stores, automotive industry, agricultural machines, surface treatment, control panels, hardening shops, textile engineering, swimming pools, air treatment, papermaking industry, environment simulation, chemical industry, industrial processing engineering, dust collection, electrical equipment. impeller vortex inducer scroll E PO Box 2889 Spartanburg, SC 29304/USA 864/ Fax 864/ TM-USA -TP (05/09) e -mail: info@ltg -Inc.net Internet: -Inc.net Former editions are invalid.
