Overview
The “Supermax” or United States Penitentiary, Administrative Maximum Facility (ADX) is a federal supermax prison located in Florence, Colorado. It houses the most dangerous inmates in the USA who are in need of the tightest control possible. Many of their inmates are very notorious high-profile criminals that present very high security risks. Inmates include Ted Kaczynski, Terry Nichols, Eric Rudolph, Zacarias Moussaoui, Ramzi Yousef and Tim McVeigh who was housed there till he was moved to federal death row and executed.
Challenges
The plumbing system in the entire penitentiary was experiencing limescale issues with their showerheads, toilets, sinks, and in the piping’s elbows and joints. Every quarter, maintenance had to shut down everything to remove the limescale buildup. The job was costly and time-consuming.
Solution
Three models were installed – the SB-350, SB-450 and the SB-MAX – on the boiler feed line, the cold water line, and the hot water recirculating loop.
Installed
August 10, 2013
Outcome
Since installation, the ScaleBlaster system has kept the entire penitentiary free from any limescale issues without any maintenance, salt or chemicals.
