ALFATERM employs high technology in the manufacturing of parts and pieces of its water cooling towers, using state-of-the-art components with higher performance and excellent raw materials to ensure maximum resistance and durability. The axial fans can be installed either at the air inlet on the side of the tower in forced draught, insufflating cold air from outside to inside, or they can be installed at the air outlet at the top of the tower in induced draught, sucking in hot air from inside to outside the tower, with air intake horizontally and air discharge vertically in an upward movement, being silenced at 76db(A). The centrifugal fans, sirocco type, are super quiet and appropriate for environments that require very low noise level such as hospitals, universities, theaters, cinemas, among others, being installed in the air intake on the side of the tower in forced draft, insufflating the cold air from outside to inside, with air intake and discharge horizontally, being super silenced at 72db(A).
