– Top gutter includes many parts being put together such as two side lids, technical lid, lid dividing water and details locating water distribution PVC tubing. Top gutter functions to distribute water sufficiently and regularly through water distribution pads to all of evaporative cooling pads being put together on a frame.
– Bottom gutter functions to take back the rest of water after evaporating on a frame of evaporative cooling pads through recovering PVC tubing to return a tank and join a new circulation. Because of containing water being taken back from the frame of evaporative cooling pads, the structure of spare parts of bottom gutter has to be tightened completely.
