Tens of thousands of plants use chlorine gas to disinfect their community’s drinking water. And while regulations may vary by individual geographies, there’s no question that if you’re going to use chlorine gas, Gas Scrubbers are an essential component for the safety of your plants, the environment, and humans. In the unlikely event of a chlorine gas leak, you need to rely on a proven, safe technology. When called into action, Gas Scrubbers must work as intended. That’s why you can depend on Capital Controls—a brand synonymous with safe and robust gas chlorination equipment for Gas Feeders and Scrubbers. Our industry experts are uniquely qualified to specify, customize, and deliver the appropriate gas scrubber solutions for you—as well as test your media and provide maintenance.

Get Peace of Mind Knowing Your Dry Scrubber Media Is Safe and Effective.
Dry scrubbers are a great choice. They are safe, user-friendly, low maintenance systems tested and proven for use in municipal and industrial applications where the potential exists for the accidental release of hazardous gases. However, your dry scrubber is only as reliable as the media inside. Be aware that even a small, undetected gas leak could cause media fouling.
Protect your assets and stay safe by enrolling in our
Dry Scrubber Media Testing Program.
Here’s how it works:
- Remove a small sample of the media from several locations in your dry scrubber from the media sample ports.
- Send the samples to De Nora.
- In approximately three weeks, De Nora will contact you to confirm the condition of your current media.
The program cost is just $295 (USD)–a small price to pay to sleep better at night. Sign up today (provide link).
What If Your Plant Uses A High Capacity Wet Scrubber?
If your plant uses a wet scrubber, keeping current with maintenance is not a choice—it’s an imperative. To help meet your maintenance requirements, you’ll want to enroll in our annual checkup program to test your pumps, blowers, sensors, and other components. The caustic itself can also get contaminated or fouled, so that should also be on the checklist as well.
