CHEM-FREE (Energy Saver / Anti-scale System)
Did you know that a mere 3.1mm of hard scale can increase your ENERGY consumption by as much as 25%? The more scale accumulated in the boiler, the more energy (money) is wasted.
The presence of scale is equivalent to having a thin film of insulation across the path of heat transfer from the furnace gases to the boiler water. This heat-insulating material retards heat transfer and causes a loss in boiler efficiency.

From the ”Non-Chemical Technologies for Scale and Hardness Control” published by U.S. Department of Energy in 1998


Boilers, cooling towers, condensers and all kinds of heat exchanger or water system such as pool and spa use water for steam generation or as heat exchange medium. CHEM-FREE Energy-saving and Anti-scaling device is a preferred technology due to its powerful descaling effect. As long as the CHEM-FREE device is installed into the water mains pipeline of the heat exchange equipment, it is able to remove and prevent scale formation. CHEM-FREE energy saving device produces a powerful energy field that creates a disturbance on the suspended charged particles in water flowing through the pipes (such as calcium ion, magnesium ion, silica, etc.), so that these particles, with silicon dioxide as core, will absorb calcium ion, magnesium ion or ferric oxide particles (Fe2O3) continuously, and form non-crystalline (aragonite) crystals that will precipitate and eventually discharged with water through blowdown

After using device for 238 days.Hard scale turns to soft sludge

Most of calcium or magnesium ions in water will form into amorphous sludge and cannot form calcite crystals with negatively charged ions,such as carbonate ion (CO) or sulfate (SO) on the surface of pipes.

The water treated by CHEM-FREE can be maintained at higher conductivity value. That means, allowing higher concentration of dissolved ions floating in suspension, without the formation of hard scale on the surface of equipment or piping. It can reduce boiler blowdown and save on energy cost.

1. Energy activated water
2. Small water cluster
3. Low surface tension
4. High solubility
5. High permeability
6. Weak Alkaline

Major ways to improve boiler system efficiency through the use of CHEM-FREE.

1) Reduce Boiler Scale
2) Minimize Boiler Blowdown
3) Reduce Feedwater to the Boiler

How will CHEM-FREE help you save money?
1. By eliminating and preventing the build up of heat wasting scale.
2. By eliminating the need for costly chemicals
3. By eliminating the need for treating the resultant pollutants
4. By reducing blowdown
5. By reducing downtime and maintenance costs
6. By protecting your investment in capital equipment

CHEM-FREE ENERGY SAVER,ANTI-SCALE AND ENVIRONMENTAL PROTECTION Boilers, cooling systems and other equipment consuming a lot of water generate hard scale which reduces equipment heat exchange efficiency. The most commonsolution is to apply chemicals and do acid cleaning, but chemical treatment is unable to solve the problem. For example, adding alkali to control PH value, or adding organic phosphorus compound or organic dispersing agent, are only effective against specific ions. When the composition of ions in water change, PH changes, foreign substances added, or the concentration of ions in water reach a certain limit, all these can make the use of chemicals useless or ineffective. When large numbers of suspended ions in the water inside the boiler or cooling system get deposited on pipes, they form a heat-insulating layer that reduces heat exchange efficiency and wastes a lot of energy. From environmental protection point of view, scale prevention method using chemicals cause damage to the environment due to the wastewater discharged on river and ocean, the future impacts of which are hard to assess.Therefore, application of CHEM-FREE is absolutely the most effective and beneficial way.
