ChemTreat field representatives are industrial cooling specialists, with extensive experience in a variety of applications. We provide expert solutions for cooling water treatment and management to help you improve operational efficiency and reduce costs. There is no one-size-fits-all solution; our water treatment programs are specifically tailored to meet the needs of your particular system.
As a cooling tower water treatment company, we can develop programs based on your facility’s specific needs. Our field representatives have expertise with all associated equipment, including evaporative condensers, shell and tube heat exchangers, plate and frame heat exchangers, etc.
ChemTreat’s expertise with closed-loop water systems includes the following:
Most chilled water systems incorporate an open recirculating system with a cooling tower for condenser cooling. Our industry-leading cooling water treatment company develops water treatment programs tailored to your facility’s specific needs. Our field representatives have expertise with all associated equipment, including evaporative condensers, shell and tube heat exchangers, plate and frame heat exchangers and more.
The most significant issues faced within the exchangers are corrosion and scale formation.
Heat exchangers remove unwanted heat and typically transfer it to a recirculating cooling water stream. While water-cooled heat exchangers are used most often (shell and tube, plate and frame), some heat exchangers are air-cooled.
Heat exchangers typically transfer unwanted heat to a recirculating cooling water stream. The cooling water temperature will be elevated as it absorbs heat from process and utility equipment, which is then expelled through partial evaporation of the water across a cooling tower. Several problems may arise in this heat transfer process as issues like corrosion, scale, fouling, and microbial growth will reduce flow rates and heat transfer rates and lower system efficiency.
ChemTreat field representatives can customize your cooling treatment program to ensure heat exchangers operate at peak efficiency and the cooling system effectively reduces the process fluid temperature. We have expertise in a variety of different heat exchanger designs including:
Once-through cooling systems are often used to remove heat from the surface condensers or to service the power and paper industries. Cooling water is only used once and then discharged, resulting in a highly water-intensive operation.
Corrosion, deposition, and microbial growth have to be controlled to maintain efficiency and reliability in a once-through cooling system. Our products include polyphosphates, silicates, and molybdates to control corrosion. Our phosphate and polymer products reduce scale and fouling, and our chlorine, bromine, and chlorine dioxide products help control microbiological activity and macro-organism fouling. We also offer phosphate-free and zinc-free treatment options for cooling systems. Read about our innovative FlexPro® product line.
These cooling water treatment chemicals have to be applied relative to the quality of the raw water supply. Problems often arise with variable raw water quality because the treatment program has to change in real-time. The best choice is to install a ChemTreat Solutions® system that will monitor the relevant water quality parameters and adjust your chemical feed rates to maintain an optimal treatment program at all times.
Open Recirculating Water Cooling TowersOpen recirculating systems provide the most common form of industrial cooling, continually recycling and reusing the same water for equipment cooling needs. In these systems, water leaving the cooling tower is pumped to industrial applications using heat exchangers, condensers, air compressor jackets, or process reactors.
In this cycle, the water returning to the cooling tower water absorbs excess heat, which is then dissipated by passing the water over a cooling tower where evaporation takes place. The cooling tower exposes the heated flowing water to air, causing a percentage (approximately 1–3%) of the water to evaporate, removing 1,000 BTUs per pound of evaporated water. This cools the water that is not evaporated, which is then recirculated through the system.
Reusing cooling water results in water and chemical savings, as the chemistries are retained in the system. However, problems associated with corrosion, deposition, and microbial growth become more severe for several reasons. First, the evaporation process concentrates the amount of dissolved and suspended solids in the circulating water, leading to deposition. Second, the warm temperatures in open recirculating cooling towers are optimal for biological growth. Third, cooling tower operation tends to scrub airborne contaminants from the air. These contaminants can accumulate in the circulating water, causing fouling and microbial growth.
ChemTreat have experience treating every kind of water cooling tower, including natural draft, mechanical, crossflow, and counterflow cooling tower designs.
