It follows rigorous production controls and conducts preventive maintenance to reduce repair costs, eliminate contamination, and prevent unplanned downtime.
The manufacturing process follows the highest levels of Canadian and international quality regulations. It meets ASTM and ISO standards, including ISO 9001:2015 and ISO 45001. This quality means your systems are built to last and run well the entire time, helping you generate a sizable return on investment.
What Makes These High-Purity Water Systems Valuable?
Value is hard to define because it is based on what drives sales, improves processes or lowers costs for your niche. However, there are a few general criteria high-purity water systems should follow. For one, it does not necessarily include the lowest-priced items. Budget options are great but may not perform as well or last as long, meaning you technically spend more in the long run.
Even if a machine is expensive, it may still be of better value, as long as it streamlines the production process, lowers monthly utility bills, improves compliance with regulations or reduces the frequency of unplanned downtime. Look for terms like “energy-efficient,” “turnkey” or “integrated” to find the best solutions.
Some suppliers offer unique value-adding features like 24-hour emergency services, preventive maintenance, free shipping or products that exceed regulatory standards. Since these vary, they are harder to compare. However, you can prioritize them based on what would be most beneficial to your operations:
| Company Name | Founded | Service Area | Main Value Drivers |
| MECO | 1928 | International | ∙ Robust compliance
∙ Custom turnkey solutions |
| US Water Systems | 2001 | Nationwide | ∙ Direct to customer
∙ Made in America |
| Serv-A-Pure | 1946 | Nationwide | ∙ Branded turnkey solutions
∙ Money-back guarantee |
| Puretec Industrial Water | 1964 | Nationwide | ∙ Energy-efficient systems
∙ Same-day order processing |
| Xylem | 2011 | International | ∙ Proprietary components
∙ Lab and packaged systems |
| High Purity Water Services | 2010 | Canada | ∙ 24-hour emergency service
∙ Robust compliance |
| ChemTreat | 1968 | Nationwide | ∙ Environmentally friendly
∙ Robust compliance |
The sales, support and technician teams can also help generate value through their services. For instance, they may help you save on vendor expenses if they offer post-sales support. Alternatively, they might sell directly to you instead of involving intermediaries, eliminating unnecessary expenses. Again, you must search for the criteria that align best with your needs.
You Should Hold Products To These Quality Standards
Most leading businesses say their high-purity water systems meet or exceed quality standards, but what does that mean, exactly? cGMP is among the most common. It ensures the water manufacturers use is safe, pure and contamination-free. The U.S. Food and Drug Administration enforces it.
Another common standard is from the American Society for Testing and Materials (ASTM), which defines types of reagent water — purified water suitable for special procedures in clinical settings, food production and pharmaceutical manufacturing. Type I is ultrapure, while Type II is purified. Type III is produced using standard tap water and RO, making it suitable for general purposes. The least pure — Type IV — is used as feed water or for noncritical work like rinsing.
FAT protocols outline systematic testing procedures and acceptance criteria manufacturing facilities use to verify that newly produced machines perform well and adhere to specifications before delivery. Ensuring they meet predefined parameters is important, especially when ordering a custom design for a critical application.
ISO 9001:2015 also applies to manufacturers. It belongs to a set of globally recognized standards developed by the International Organization for Standardization. The regulation applies to quality management systems, specifying requirements for when a firm must demonstrate its ability to provide consistent services and conform to regulatory requirements. Since it is generic, it applies to organizations of all types and sizes.
Which Of These High-Purity Water Systems Will You Pick?
The high-purity water system you choose will reflect on your operational efficiency and product quality, so it is important to make the right choice. Advanced filtration solutions eliminate almost all impurities and contaminants, making them ideal even for the most demanding applications. However, you should consider extra features and services to decide which works best for you.
