Two Modern Plants--St. Louis, Mo., and Plainview, Texas INDUCED DRAFT TOWERS New type filling reduces static pressure. Filling consists of slats, assembled in grids. Slat arrangement insures maximum wetted surface, minimum pressure drop of air .flowing through tower packing, and uniform distribution of water and air over the entire effective area within the tower. Gravity distribution system requires only one riser pipe. Teco timber connectors develop 100 per cent working stress of members. Normally constructed of selected California redwood. All fans furnished by LilieHoffmann are P.F.M.A. tested and certified. ATMOSPHERIC SPRAY TYPE Generally offered in capacities up to 3000 gpm. Distribution by galvanized pipe header with smaller lateral arms, equipped with non-clogging spray noz zles. Water atomized as finely as possi ble. Sides and ends of towers equipped with narrow louvres, which fit into mast slots--no nails required. Recommended where cost is prime factor; and close approach to wet bulb is unnecessary.
