Systems that automatically control pH and conductivity, such as Closed Loop Systems, work just fine ... but ... we all know that it is NOT a perfect world. Sometimes chemistry is damaged in shipment or as a result of other
environmental factors ...
So ... the REAL QUESTION is: How do you compensate for variations in chemistry?
Closed Loop Conductivity Mixing assumes that any variation if conductivity is always because of the water quality and it automatically adjusts the chemisty amount to compensate for this. If there’s
something wrong with the chemistry you end up with both costly paper waste and extended downtime while you try to find out what’s causing the problem.
Using a Closed Loop System is like playing Russian Roulette ... Sooner or later you’re going to have a BIG problem!
PMX technology directly controls chemistry by volume rather than indirectly controlling it through conductivity. The PMX monitors, rather than controls conductivity ... so ... it lets you know when something is wrong before it becomes a problem!
