When people think Culligan, they think drinking water… at least I do typically. As a matter of fact, just writing that sentence made me thirsty, so apparently their marketing has been working it’s magic on me. Culligan was founded in 1936 by Emmett Culligan, an entrepreneur who introduced the world to soft water in 1921. Since then the company has emerged as the world’s leading water treatment company. Their website title bar gives a good summary of what the company is about – water filters, water softeners, drinking water and water treatment.

So now that I’m back with a glass of water, what many people probably don’t realize is that Culligan isn’t really a water-supplier, they’re (as previously stated, in case you glossed over it) a water treatment company. But if you think about it, it makes total sense. The whole reason that Culligan’s drinking water tastes so good is because of the water treatment.

For example, Culligan’s Aqua-Cleer® Drinking Water System, promoted as their “most innovative water filtration system available today” includes 13 filters that reduce impurities of all kinds (including sediment, chlorine, lead, radium and arsenic). Though, for some reason it’s not approved for sale in California or Wisconsin.

But this article isn’t about potable water treatment, tasty though it may be. We’re focusing on HVAC water treatment (specifically deionization), so for that we turn to Culligan Matrix Solutions, the commercial and industrial arm of the company.

Deionization is the process in which dissolved salts are removed via ion exchange resins. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, quickly and without scale buildup. Culligan Matrix Solutions offers three main deionization solutions: Portable Exchange Deionization (PEDI), Continuous Electro Deionization (CEDI) and Automatic Deionization (Filter DI).

I mentioned that these deionization systems can be implemented for HVAC applications (boiler feed, cooling tower makeup, humidification, etc) but DI water has many other uses such as in medical or dental facilities, manufacturing, battery water, printing, laboratories, electronics… you get the idea.

The PEDI system process was designed to meet the needs of businesses requiring high-purity water for a variety of commercial applications. Tanks are available in fiberglass or stainless steel construction and regeneration or exchange is provided by a Culligan dealer. This system reduces on-site labor and regenerant chemical handling. The CEDI process removes ions from liquids using electrically active media and an electrical potential to affection transport. Automatic DI (Pro Series DI) is part of a multiple process treatment system that produces high quality water required for specialized applications. A flexible configuration of mixed-bed or strong acid-base resin tanks is simple to manage, and the owner has the option to automatically or manually control the process.

Of course, Culligan is a consulting company as well, so more detailed information about their products and systems can be gathered by setting up a free commercial consultation.
