Detailed description of the low-noise cooling tower design of energy-saving motors, good sealing waterproof performance, high temperature, high efficiency, low noise. Deceleration device: a polyester fiber reinforced neoprene belt drive power, high temperature, high efficiency, water does not stretch to overcome the slippage, the noise is small. Sound absorption facilities: ultra low noise cooling towers in outside air intake increased with sound-absorbing materials and equipped with sound-absorbing gate in two from top to bottom, in order to achieve maximum noise reduction. Outlet on the tower bell and the sound absorption gate installed with sound-absorbing material, reducing the fan and motor noise coming out. Into the windshield: steel with glass louvres, reduce floating in water, air resistance, especially for the northern region and the need to use all year round cooling tower units.
