In this work, it is presented the design of a laboratory scale cooling tower with wood splash type packing to make an experimental study on terms of the volumetric mass transfer coefficient (kya), water to air flow ratio (L/G) and inlet water temperature. The performance of the tower was evaluated at different mass flow ratios of water to air (L/G) in the range from 0.22 to 1.1, and water inlet temperature from 40 o C to 48 o C. It was found that the tower efficiency had an exponential decay

The values of kya decrease when the water inlet temperature increases for low values of L/G in the range from 0.22 to 0.66. This effect decreases for high values of L/G. The effect of the inlet water temperature in the efficiency is negligible.
