CompuPool of Australia was formally Compuchlor.  They have redesigned their chlorinators and produce one the best Salt Chlorinators in the industry and a good price and good warranty.  

They also manufacture the CircuPool Brand of Salt Chlorinators

Salt Levels for the CPSC models is 3500 ppm minimum

All units are self Cleaning Reverse Polarity Models.

If you are replacing a Poolpower,  Clevachlor or Quikchlor this is the perfect choice. It has the timer function, but also gives you salt read out, Temperature readout and winter mode which the others do not.  It is by far the best Salt Chloroinator available now to replace those models.   Or any other chorinator that has a built in Timer.
