FAQ Water Treatment Solutions

Water quality is critical to maintaining your systems at peak efficiency and reliability. Systems and processes that use water to operate are affected by the quality of the source and circulated water. This includes boilers, cooling towers, closed loops, etc.

Water treatment is an investment to protect your systems and ensure years of reliable, efficient service. As you search for a water treatment solution, there are several important questions to ask. At Guardian Chemicals, we understand the stakes and develop customized water treatment solutions for you.

Why is water treatment important?

Water needs to be treated to prevent corrosion, scale deposition and microbial growth. The best water treatment programs prevent these issues and protect your boiler, cooling and closed loop systems. We take a holistic approach to water. Our programs combine water treatment chemicals, equipment, remote monitoring and service. This ensures your heating and cooling systems are well-maintained, reliable, and efficient. Best of all, our water treatment programs extend equipment life, reduce overall costs, and enhance sustainability.

What are the best water treatment chemicals?

When it comes to water treatment, there is no one-size-fits-all approach. Water treatment chemistry is tailored to meet the demands of each system. Hot water heating boilers require different solutions than steam boilers with condensate systems. Closed loop heating and cooling systems require different solutions than cooling towers. That’s why you need to partner with a water treatment solutions company with the right chemistry and expertise to help you succeed.

Which water treatment system is best?

There is no one best system. Water treatment systems and programs are customized to the industry, building and application. Water treatment programs consist of many chemistries, each addressing a specific system need. We develop customized water treatment solutions for you to meet the needs of your system. Our holistic approach ensures reliable, predictable results.
