The Aquasol line of controllers analyze the water, based on the number of swimmers, the environment, and dispenses the proper amount of required chemicals to the pool. Handling pools chemicals can be the most dangerous part of pool maintenance. A controller makes it safer for workers who will not be required to manually handle the chemicals. The addition of our Safety Pressure Switch further assures a sufficient water flow before the controller dispenses the chemicals, thus protecting from the formation of chlorine gases in a dry line.
