The CircuPool RJ16 PLUS is an electronic chlorine generator with advanced, third-generation salt pool technology. RJ PLUS models feature electrolytic titanium cells with rare-earth minerals, providing an extended-lifespan cell (as much as 50% longer than other leading brands).

The salt chlorinator works with all existing pump and filtration systems to reliably supply the swimming pool with pure chlorine every single day! The RJ16 PLUS has a 16,000 gallons max capacity. The RJ-PLUS series uses low salt levels and helps create a silky soft feeling in the pool water, for the ultimate swimming experience.

The complete RJ-PLUS salt system from CircuPool features three main components: the Control Module, the Electrolytic Cell, and the Flow Switch, along with the usual miscellaneous hardware and documentation for install.

The RJ PLUS-Series will replace Hayward Aqua Rite systems with no cutting or gluing, making it a snap to upgrade your salt pool system!


  • USA Titanium Cell, with industry-leading 7-Year Limited Warranty.
  • 3rd-Generation system, combining the best in advanced technology with a reliable and proven track record.
  • Cell has industry-leading lifespan (as much as 50% longer lasting). Longer cell-life means even greater savings over the years.

Q & A

Q: what is the difference between SJ & the RJ systems?

Asked by: Bill - 3/6/2017
A: Great question. Beside the main differences in power and lifespan, here are a few of the things that set them apart once they are in your hands:

The SJ models are very simple, easy-to-use systems. They have status lights that verify the unit is working, tell you at what power level it is set, and whether you need to clean the cell or add salt to the pool. Because it is simple there is less to think about, it is particularly low maintenance (no acid is required to clean the cell), and it is also less expensive.

The RJ and RJ+ models are the flagship systems. They are more powerful and longer lasting. They have a digital screen and touch keypad, giving you more control and diagnostics. It displays the salinity level in real time, calculates the running average, displays the water temperature, and displays the electronic performance levels of the cell so you can see exactly how things are working. The power levels on the RJ models can be turned up and down in smaller increments. RJ models also synchronize more easily with variable-speed pumps if you plan to upgrade.

So the SJ gives you simplicity and a huge value, and the RJ gives you top of the line performance and control.

Q: Is the RJ16+ cell a drop in replacement for the Hayward AQ-TROL-RJ cell? Or is some plumbing changes required? We have 14K gal salt water cell and need to replace the salt chlorine generator and cell. Thanks

Asked by: Gary Tilley - 8/12/2017
A: The RJ16+ cell will have the same length and same threaded connections as the standard Hayward Aqua Rite style cell. The RJ does use the standard saltwater chlorinator flow switch, so if your AQ-TROL-RJ didn't utilize a flow switch, it is a simple task to add the new one that comes with the RJ16+. Overall it is a relatively easy swap.

Q: Does this unit run on 120 or 240 volts?

Asked by: Rick - 3/23/2017
A: This unit can work on either voltage. Most pools utilize 220V, so the default setting for this salt chlorinator is 220V, however instructions show you how to change the input power setting to 110V if that is what you need. For this equipment, there is no advantage to either voltage, you just want to match what your pump is using.

Q: I have a 17800 gallon pool. Which one should I get.

Asked by: Claybow - 3/7/2020
A: You typically want a system that has 1.5x to 2x your pool's actual capacity. I would recommend at least the RJ30+ model for you, but bigger is always better.

Q: how does this compare to the Haward Aquarite 15?

Asked by: TOM - 6/11/2018
A: The RJ-Plus series has a 7-year warranty, 15000 hour lifespan cell, controls with OLED display and die-cast aluminum heatsink, and a clear cell.

The Aquarite has a 3-year warranty, 10000 hour lifespan cell, controls with LCD display and sheetmetal control box, and a opaque cell.

The RJ16 Plus has 0.7 lbs/day chlorine output and is meant for 16000 gallons max. You wouldn't directly compare its size, as the AQR15 has 1.4 lbs/day chlorine output and is meant for 40000 gallons max. You would maybe want to compare it to the RJ30+ or RJ45+ sizes.

Q: we have an Aqua Rite electronic chlorine generator that is about 12 years old. The salt cell is a model cell- 15 Turbo Goldline that has appeared to fail. System is not generating chlorine. Cell has been cleaned. Salt in pool is 4000ppm. Check cell lite remains on. Will the CircuPool RJ-16 plus salt chlorine generator be an exact fit for the cell? How will this compare to the Aqua Rite brand.

Asked by: June - 9/3/2019
A: The RJ models will be an exact fit, meaning it is very easy replace an old Aquarite. If you have an old T-15, you would want either the RJ-30 or RJ-45 size so that you get about the same or more chlorine output (capacity). Those models have logner lifespan, longer warranty, better controls/electronics, and other features that make it easier to use as well.
