In every cooling tower there is loss of water to the environment due to evaporative cooling process.
Drift , however is the undesirable loss of liquid water to the environments via small droplets that became entrained in the leaving air stream. Their water droplets carry with them chemicals and minerals thus impacting the surrounding environment.
Drift Eliminators are designed to capture large water droplets caught in the cooling tower stream. The eliminators prevent the water droplets and mist from escaping the cooling tower.
