Cooling Water Chemistry

Other water treatment methods are inaccurate, dangerous or difficult to use and can be very costly. ProChemTech took all these concerns to heart when developing our own unique chemistry for cooling systems. Our chemistry is more effective at preventing rust and scale build up on a system than our competitors. It is also more user friendly and safer allowing our customers to better understand their water systems without the risk of hazardous chemicals. ProChemTech is always innovating and creating new products to better improve our customer’s way of life.


Shortages of fresh water and increased costs for both makeup water and blowdown disposal have created a need to increase the cycles of concentration in cooling tower systems. Unfortunately, increased cycles of concentration also increases the concentration of hardness ions in the cooling water, making the cycled waters highly scale forming. Formation of hardness scale in heat exchangers is unwanted, as even a small amount of scale will decrease the efficiency of heat transfer, resulting in increased power consumption for chiller operation and decreased productivity in industrial processes. In severe cases, scale can also completely plug heat exchangers and piping.

Operation of cooling towers with cation exchanged makeup water was first started in 1984 at Brockway Glass Company. A successful program, directed by Timothy Keister, was created to control scale in extremely high heat flux furnace electrode cooling jackets. Building off the original processes ProChemTech International has developed and refined this ground breaking technology into a complete patented water management technology Aqua-Ionic™. This revolutionary treatment process addresses the need for increased cycles of concentration while maintaining control of scale, deposition, and corrosion at a reasonable cost.

From the start the benefits of this technology are immediately obvious to facilities that have suffered from the problems caused by scale formation in cooling systems or the corrosion damage resulting from upsets in acid feed pH control systems. Use of cation exchanged water immediately eliminates the scale potential of the cooling water, rendering it non-scale forming, while completely eliminating any further need for pH control via feed of corrosive and dangerous acids.

ProChemTech has developed an entire family of cost effective Aqua-Ionic™ products for everyone’s water system. There is an Aqua-Ionic™ product made to control corrosion of ferrous, galvanize, aluminum, zinc, and yellow metals in a cation exchanged water environment.


When looking at resource consumption of a building the air conditioning cooling towers are often the largest consumer of water. These systems can consume up to 35% of total input water to a facility. A large part of this high water use is from the cooling tower requiring blowdown to prevent scale formation in the cooling tower. This is a large waste of water for something that can easily be solved with ProChemTech’s patented chemistry. Aqua-Save™ advanced multipolymer technology prevents scale formation in the system, while reducing blowdown amounts. When compared to standard chemical treatment technology for a cooling tower our system on average has a 50% reduction in water wasted because of blowdown.

In addition to substantially reducing water and sewer costs, an Aqua-Save™ program is typically a simple “drop–in” replacement system. This means often switching to Aqua-Save™ does not require new chemical control or feed equipment thus making the switch quick and cheap.

Unlike many non-chemical devices and water use reduction schemes, Aqua-Save™ is a proven technology.

Blue Trace™

In cooling water systems better control of chemical dosages provide significant benefits such as lower operating costs, prevention of scale and corrosion in the system. Our unique patented BlueTrace™ tracer colorant is the solution to this task. Bluetrace™ provides a cost effective, quantum leap in performance over previous means for control of treatment chemical level in cooling water. With a cost-effective non-toxic organic colorant, bluetrace can be added to the majority of our cooling water inhibitor chemistry. This provides our technicians with an accurate and quick test procedure for checking the chemistry in the system. This also allows customers to quickly determine if their systems chemistry is suffering an upset or working properly without requiring lots of additional testing or training.

When combined with ProChemTech’s BlueTrak™ automatic controller it provides our customers with the most accurate and reliable chemical automation on the market today. You can learn more about the Bluetrak™ system at the link below.

Recognizing the need for a simple, reliable cure for the white rust problem, ProChemTech initiated research into new corrosion inhibitors. After two years of research these efforts were successful with the creation of a new inhibitor technology, GalvaGard. This unique technology is available in a wide array of ProChemTech formulations. It is suitable for makeup waters ranging from soft to extremely hard and with any level of alkalinity. GalvaGard has also been formulated into an adjunct product for use with existing water management programs and is also available as a concentrate for use by toll product blenders and other water management firms.


  • Is a specific organic chemical compound found to directly inhibit corrosion of zinc (galvanized steel) in contact with alkaline waters.

  • Is available incorporated into various blended products produced by ProChemTech such as our Trademarked Aqua-Save, Aqua-Ionic, and Zero Blowdown Technology as well as all organic and traditional water treatment chemistries.

  • Protection against white rust is available at a slight increase in water management program costs.

  • Eliminates the need to pretreat cooling towers for ineffective passivation.

  • Eliminates the need to reduce cooling water pH below 8.2 for control of white rust.

  • Allows operation at economical higher COC without fear of white rust damage to expensive cooling towers.
