As we say repeatedly, proper water distribution is literally the key to cooling tower thermal performance. If this piece of the puzzle is missing, your cooling tower will never meet your design specifications.
In some cases, the water pressure in your cooling tower has become inadequate to properly “pressure” your fixed orifice system. As a result, your water distribution system is essentially a drainage system. Not good.
Our Variable Flow Nozzle is spring loaded which means that until the entire water distribution system is “pressured up” no water will drain out of the nozzle. Once the proper pressure (about 1 pound) is met the nozzle spring will allow water to exit the nozzles and spray our square pattern.
