Welcome to Scale Free Systems

Home of the patented

non-chemical, non-magnetic water treatment, scale prevention and removal, corrosion control, and

bacteria and algae control system.

Brief History of SFS

• Established the Scale Free process over 20 years ago in St. Louis under the name NoKem.

• Scale Free Systems was bought out by Meeh Mechanical Contracting Co. in 1991.

• SFS was redesigned with control systems, which included the copper/silver ionization control system.

SFS water treatment processFeatures

• Eliminates & reverses scale/corrosion• Prevents bacteria, Legionella, & algae growth• Regulates conductivity control• Eliminate daily operating care• Protect against corrosion• Increase heating efficiency from 10%-20%• Water savings

Principles of SFS

• Chemical– Uses chemicals to treat the water

• Other non-chemical treatments– Uses magnetic waves to treat the water.

• SFS– Treats the equipment, not the water.

Principles of SFS

• Positive particles in the water are attracted to the negative charged pipes and equipment. This causes scaling and corrosion.

• Electricity will always follow the path of least resistance.

• By neutralizing the equipment, we can prevent scaling and corrosion.

How SFS works for scale and corrosion…

• Galvanic action between probe and equipment.

• Control panel regulates and controls the flow of electrical energy.

• Ground connections to pipe and equipment.

• Install a separate grounding system

How SFS works with bacteria and algae control…

• Copper/silver ionizaton.• Copper levels don’t

evaporate.• Control system regulates

the time and usage of copper/silver ions into the water.

Standard Bacteria Water Test Results

• Cooling tower water – less than 10,000 CFU’s

• Drinking water – less than 500 CFU’s

• SFS water test results – 329 CFU’s
