The Innovation Company LTG Aktiengesellschaft LTG Tangential Fans an advantage for best 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 . 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 LTG tangential fans are used for needs of regular air flow over large areas: Heating, cooling, drying and dust collection. Examples of typical fields of application are bakeries, drying systems, industrial ovens, packaging industry, cooling and refrigeration, department stores, automobile 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 LTG Aktiengesellschaft ⋅ Grenzstraße 7 ⋅ D-70435 Stuttgart ⋅ +49 (0711) 8201-180 ⋅ Fax -696 TW-- E-TP (11/06) Internet: http://www.LTG-AG.de ⋅ E-Mail: [email protected] ⋅ Printed in Germany ⋅ Ausgaben mit früherem Datum werden hiermit ungültig ⋅ Technische Änderungen vorbehalten ⋅ Former editions are invalid ⋅ Subject to technical modifications. 3 The Innovation Company LTG Aktiengesellschaft LTG Tangential Fans Type TW, Impeller Diameter 150 mm The tangential fan series TW 150 is a rigid industrial grade fan with enhanced corrosion protection and high power density.

Any arrangement is possible. Rigid bolted, corrosion proof casing of marine grade aluminium (DIN 1725). Impeller of galvanized steel. Installation and Start Up The impeller is both sides bedded in self-- aligning ball bearings. Bearing design life is 25 000 hours. The counterside bearing is mounted vibration dampened. Both bearings are lifetime lubricated. Recommended V-- belt pulley: profile SPA 12.5 mm (0.49 inch), dw = 160 mm (6.3 inch). DIN 7753. The maximum rated power transmission for the pulley is 9 kW (12 hp). Intake and discharge openings have sealing planes and plug in slots to connect exactly to ducts and appliances. The complete fan (including bearing clearance etc.) is balanced to grade Q 6.3 according to VDI 2060. Fix the fans without any distortion to a plane base frame. For fixation of the fan use only the bolt holes provided in the side elements. To connect to ducts and appliances sealing planes are provided over the whole fan width for the intake and discharge openings. Make sure to observe the applicable safety codes before starting the fans. Check V-- belt selection for higher temperature applications. The fans are designed for continuous operation with constant load (operation mode S1 analogous to VDE 0530): For frequent start/stop operation please check with LTG. Length tolerances acc. to ISO 2768 vL.

The acoustical data are for discharge side, tested in a reverberant field. The A-- weighted sound power level LWA can be transformed into a A-- weighted sound pressure level LPA by the equation LPA=LWA- 10 log s/1 m2. Accessories and Special Versions The sound pressure level in the free field in 1 m distance (full spheric sound radiation) is abt. 11 dB less than the sound power level. For extra high corrosion protection requirements, the impellers can be made of stainless steel. Belt pulley: V-- belt pulley with sleeve, dW = 160 mm (6.3 inch), profile SPA 12.5 mm (0.49 inch), DIN 7753. The equation for the unweighted sound power level according to VDI 2081 is: LW=LWspecific+10 log V + 20 log ∆pt For the total pressure ∆pt use Pa and for the air volume V use m3/s.
