Our selection of quality products along with our services is what we are known for. We offer a wide variety of options that will suit each clients' requirements. Get in touch with us today to see what we can do for you.

Cooling Tower

Our cooling tower water treatment chemicals are tailor-made to protect your systems while increasing efficiency, so that you can reduce operating costs.

CSL treatment for cooling towers include:

  • Scale prevention/deposit control

  • Corrosion control

  • Microbiological control​

Open recirculation systems that are effectively treated keep your equipment operating for longer periods and more efficiently, maintaining peak levels of production. CSL has the products and services to ensure deposit control, scale control, corrosion control and microbiological growth.

Closed loop systems which require corrosion and biological control. CSL's complete line of treatment products allow your closed loop cooling systems to operate efficiently.


Maintaining a reliable system while keeping your equipment safe and lowering your operating costs is what we envisage for you. With our assistance you get effective boiler chemical treatments, quality services, as well as solutions specifically designed for your system.

With over 39 years of experience in this field, CSL combines its efforts with you to obtain solutions for your most pressing concerns.

Feed water treatment chemicals reduce corrosion and scavenge oxygen in the feed water process, in order to protect your equipment from unscheduled downtimes and unnecessary damages. Such treatment minimizes the amount of metal oxides entering the boiler. Therefore, maintaining clean boiler tube surfaces and improving fuel efficiency.

Boiler internal treatment chemicals keep the boiler tube surfaces clean and reduce corrosion, lowering the probability of overheating. Controlling deposition and corrosion raises plant reliability and availability, protects equipment, and minimizes fuel and maintenance costs. Anti-foamers can also reduce the boiler water to carry over to the steam, therefore keeping your superheaters and steam turbines away from potential damage.

Fuel treatment chemicals are capable of reducing deposition and slagging and can improve combustion. Equipment can be protected from the failure caused by corrosion, fuel efficiency is gained and maintenance costs can be minimized. Fuel additives can assist in attaining important environmental regulations. It all depends on the type of fuel and the objective in mind.

Reverse Osmosis (RO)

Our reverse osmosis chemicals improve performance of your membranes.

Impurities that compound on the membrane surface during operations can hinder the RO membrane's performance. Such impurities might account for suspended solids, microorganisms and mineral scale, causing a loss in output and/or rejection levels and negatively impact total system performance.

CSL offers a large range of treatment chemicals to help you improve the performance of your RO membranes.

Coagulants and Flocculants from CSL can improve pre-filtration efficiency and assist in increasing productivity in membrane systems for RO feed water.

Anti-scalants and pretreatment chemicals from are designed to get rid of scale and prevent fouling in membrane systems, no matter the feed water source.

Dechlorination products by CSL include a simple, ready to use product for potable applications.

Cleaning chemicals will provide your membrane the service it needs to maintain its effectiveness and productivity. CSL can provide cleaning chemicals to obtain the most effective results.

Microbiological control chemicals will allow for effective control of bacterial growth and slime.

In addition to our range of water treatment chemicals we provide top quality technical services. ​

  • Water analysis

  • Technical field support

  • System troubleshooting


CSL offers the most advanced and complete line of treatments for wastewater. Our treatments, using speciality chemicals, remove pollutants, reduce sludge handling and disposal costs, improve effluent quality, promote recycling and water saving. With our specially trained on-site chemical engineers we can help you overcome a range of challenges through:

Clarification is the process in which contaminants are removed from incoming water to make it suitable for potable or industrial uses, or from expelled water to agree with regulatory compliances concerning discharge or reuse.

CSL provides influent water treatment chemicals that remove organic color, calcium and magnesium hardness, iron and suspended solids by applying specifically-tailored blends for each unique application. Thus, in turn, improving boiler and cooling tower efficiency, performance of scale inhibitors and process operations and lead to cleaner, clearer drinking water.

We also provide the necessary resources to make effluent/wastewater acceptable for reuse or discharge. Our treatment improves the effluent clarity in primary clarifiers and speeds up the settling of suspended biological solids in secondary clarifiers. Treatment also helps to reduce the volume and moisture levels of sludge.

Metals removal in waste streams can be minimized by using CSL's specialty treatment chemicals. No matter, the metals (lead, copper, chromium, nickel, iron, or manganese) you use or produce, CSL treatment can provide the right tools to manage the wastewater.

Odor control can be sustained using CSL's range of advance products for cost-effective odor control in water processing. This can be applied to areas, such as membrane filtration, ozone treatment systems, and objectionable odors (hydrogen sulfide and mercaptan).
