The COOLING PAD works according to the principle of evaporative cooling and is able to cool sufficiently. By using the heat from the surrounding air to evaporative cool, water from its surface then it is capable of cooling by up to, 10 to 20C (50-72F). The ability to cool air depends on conditions such as air temperature, thickness of the pad, and velocity of air. To maximize the properties of the pads, equal wetting of the pads is recommended and the pads should also be well maintained. In a wide range of environments, this COOLING PAD is perfect for lessening heat and is a functional item for cooling needs.
