How Should Multiple SWG Cells be Setup in a Pool?
Why are Multiple SWG Cells Needed in a Pool?
Sometimes a pool needs the generating capacity of more than one Salt Water chlorine Generator(SWG). This may be because the pool volume is greater than the capacity of a single cell; too small a cell was installed and additional capacity is needed; or you want the redundancy of multiple cells in case one cell fails.
Depending on the manufacture the largest cell in their product line may be for a 40,000, or 60,000 gallon pool. Note that manufactures specification assume the cell is run 24/7 at 100% of capacity. At TFP we recommend you oversize your cell by at least 2X your pool volume. A 40K cell is best for pools 20,000 gallons of below.
Oversizing the SWG capacity creates challenges for large pools of around 40,000 gallons and above. In those situations installing multiple cells may be the solution.
Connecting Multiple SWG Cells Serial or Parallel?
Manufacturers
Pentair Commercial IntelliChlor Commercial Systems (COMSYS)
The Pentair commercial systems come in cell configurations from 2 to 8 cells producing 4lbs of chlorine per day to 16lbs of chlorine per day
IntelliChlor COMSYS-6 System 520972
The IntelliChlor COMSYS-6 System 520972 consists of three IntelliChlor (SCG) cells and three powercenters (one primary and three secondary). Each cell can produce up to 2.00 lbs of pure chlorine per 24 hours of operation. These cells can sanitize either a pool or spa, or combination of both.[1]
The COMSYS-6 uses IC60 like cells where each cell produces 2.00 pounds of chlorine per 24 hours for a total output of 6-lbs of chlorine per day. One cell is the PRIMARY and the others are the SECONDARY. The PRIMARY reads the salt level and communicates to the SECONDARY cells through the Power Center communication connections.
The cells are positioned vertically and connected with parallel water flow through Pentair supplied manifolds.
The cells used in the COMSYS are different than the residential IC60 cells in that they are setup to be a PRIMARY or SECONDARY cell and commercial coated cell blades.

- 521005 IntelliChlor Secondary Cells
IntelliChlor COMSYS-16 System 520977
The IntelliChlor COMSYS-16 uses seven additional secondary cells and manifolds to support a 150,000 gallon pool. This setup runs water through the manifold in four parallel paths with two cells in series in each water path.
