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 864/599-6340 Fax 864/599-6344 TM-USA -TP (05/09) e -mail: info@ltg -Inc.net Internet: www.ltg -Inc.net Former editions are invalid.

LTG Tangential Fan Type TM 125 / TM 150 / TMt 150 Position of the fan Standard arrangement is horizontal. For vertical mounting the motor is located at the bottom. Installation and start up Fix the fans without any distortion to a plane base frame. For fixation use only the bolt holes provided in the side elements. To connect to ducts and appliances plug in slots and 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. The fans are designed for continous operation with constant load (operation mode S1 according to VDE 0530). For frequent start/stop operation please check with LTG. To keep the ambient temperature below max. at the bearings, it is necessary to insulate the side elements on site. Motor arrangement With the suction opening on top, viewed against the discharge opening, the drive motor is optional either right (TMR) or left (TML) hand side. Electrical equipment The fan is driven by a 4-pole 3-phase motor, 400 V/460 V / 50/60 Hz. Enclosure is according DIN 40050. This gives protection against dust deposits and low-pressure jets from any direction. The motor coil insulation below nominal length 864 is class B, from nominal length up to 1264 it is class F according to VDE 0530. Dimensions in mm d Plug in slots 6 mm deep for duct connection, max. 1.5 mm sheet thickness K slots for self -tapping screws, 4.2 mm, max. 10 mm screw in depth D slots for self -tapping screws, 3.9 (3.5) mm, max. 7.5 mm screw in depth Plug in slots over the full fan width Typical installation of type TMt with on site insulation E PO Box 2889 Spartanburg, SC 29304/USA 864/599-6340 Fax 864/599-6344 TM-USA -TP (05/09) e -mail: info@ltg -Inc.net Internet: www.ltg -Inc.net Former editions are invalid.

The rating tests where done as labortory test according to VDI 2044 with unrestricted inlet and disccharge. Acoustical data The acoustical data are for discharge side, tested in a reverberant field. The A-weighted sound power level can be transformed into a A-weighted sound power level by the equation L pa = -10xlogS/1m 2. For this the exact total applicable panel area S can be used.

LTG Tangential Fan Type TM 150 / TMt 150 Fan curves Test conditions for the fan curves The indicated curves are valid for an air density of ρ = 0.075 lb/cuft (1.2 kg/m 3), a supply voltage of U = 460 V with f = 60 Hz, if operated with a 4 pole motor. The rating tests where done as labortory test according to VDI 2044 with unrestricted inlet and disccharge. Acoustical data The acoustical data are for discharge side, tested in a reverberant field. The A-weighted sound power level can be transformed into a A-weighted sound power level by the equation L pa = -10xlogS/1m 2. For this the exact total applicable panel area S can be used. The sound pressure level in the free field in 3 distance (full spheric sound radiation) is abt. 11 db less than the sound power level. 2000 ρ = 0.075 lb/cuft 4.0 1.40 108 1950 0.7 3.5 1.25 104 1900 3.0 1.10 1850 10 1750 pf [ wg] 0.4 0.3 2.5 2.0 1.5 0.95 0. 5 96 92 88 1700 1650 0.2 0.1 rpm 1.0 0 0.35 84 1600 0.0 0.0 0.20 0 1250 1500 1750 2000 Vol. [cfm] 0.4 1.0 1.2 1.4 1.6 1.8 p d [ wg] 76 Fan curves for 401 mm (15.79 ) nominal length, 60 Hz E PO Box 2889 Spartanburg, SC 29304/USA 864/599-6340 Fax 864/599-6344 TM-USA -TP (05/09) e -mail: info@ltg -Inc.net Internet: www.ltg -Inc.net Former editions are invalid.
