Product Description

Pureline Crystal Pure Max Salt System

Thye Crystal Pure Max Salt System converts ordinary salt water to chlorine eliminating the need to purchase and handle chlorine. The chlorine which is produced is softer than traditional chlorine meaning a more enjoyable swimming experience for you and your family.

One of the top features of the Crystal Pure Max is its built-in salt meter which provides very accurate salt readings. Other salt systems base their salt readings off of temperature variations which can be inaccurate and can cause false system shut-offs.

What is the difference between this and the PL7700

A  Answered on 3/31/2019 by InyoPools Product Specialist Lennox H.

Hi. The design of the systems are different. The Crystal Pure Max system has all controls and functionality built-in to the cell with an external Power Center and the Crystal Pure PL7700 system has all the functionality and display in the controller with a separate cell and flow switch.
