What is Master-Trol®?

Acorn Engineering Company’s original Master-Trol® system has provided a means of control and water savings for over 20 years. Now Acorn is introducing the Master-Trol® Plus, a modern-day improvement on our original Master-Trol® system.


What’s New With Master-Trol® Plus?

Master-Trol® Plus is most commonly used in correctional applications to monitor and maintain control over water usage and to save water. Master-Trol® Plus also prevents inmates from flooding correctional facilities and hiding contraband. It can potentially reduce water usage by 68% or more.
