Tablet chlorinators for filtration circuits
A chlorinator gradually dissolves tablets in the water passing through the dispenser. Its setting determines product delivery but does not itself measure the pool's chlorine level. Continue checking the resulting concentration with a tester.
In-line installation or tubing connections
The Pentair Rainbow 320-C fits directly into the pipework and has 50/63 mm solvent-weld connections. Its transparent body makes the remaining contents easier to see.
The Pentair Rainbow 300-C connects via tubing to tapping points in the pipework. The listed version has a capacity of 2.2 kg, equivalent to eleven 200 g tablets. The main difference between these models is their installation method.
Tablets and operation
Use only the chemical type and tablet size permitted by the dispenser manufacturer. Do not mix different chemical types inside it. Positioning in the circuit, flow adjustment, safe opening and refilling follow the particular chlorinator's manual.
