Operates at depths up to 50 ft.
Built for potable tanks and reservoirs
Repairable design helps control long-term costs

Voltage/Phase/Frequency:

120V/1Ph/60Hz

120V/1Ph/60Hz120V is standard household power and works great for small ponds and light‑duty equipment. It’s simple to install but doesn’t provide enough power for larger lakes or high‑flow systems.
208-240V/1Ph/60Hz208–240V single‑phase gives you more power for medium‑sized aerators, fountains, and pumps. It’s common in residential and light‑commercial settings and offers noticeably better performance than 120V.

Testimonials for CertiSafe™ Tank Mixer

"In the summer months we were having lower residual due to heat. Since we got the CertiSafe Mixer, it equalized all the water and made one residual throughout the entire tank."

Shon | Rockwall, TX

"The general concern we had with our water tank is water age and degradation of the chlorine residual. The CertiSafe Mixers helped the chlorine residuals rise inside the tank itself and really helped reduce our workload."

Randy | Keller, TX

"We have two elevated water towers here in Prescott that can hold 250,000 gallons of water each. A problem we face is the cold temperatures can cause ice formation at the top. Since we installed the CertiSafe Mixer, we haven't even worried about buildup because it creates a constant flow of water that's being mixed all the time."

Matt Holman | Prescott, WI

FAQs

How does active mixing improve water quality in tanks?

Active mixing circulates water continuously, keeping temperature and disinfectant levels uniform. This prevents stagnation, supports consistent water quality, and helps ensure safe, reliable drinking water delivery.

What problems does a tank mixer help prevent in tanks?

A tank mixer helps prevent stratification, residual loss, biofilm buildup, nitrification, and sediment accumulation. These issues can impact water safety, compliance, and system performance if left untreated.

How does mixing help maintain chlorine levels in tanks?

Mixing distributes chlorine evenly throughout the tank, preventing low residual zones. This helps maintain effective disinfection, reduces bacterial growth risk, and supports overall drinking water quality.

Can a mixer reduce taste and odor issues in water tanks?

Yes, a mixer helps eliminate stagnation and uneven conditions that cause taste and odor variations. By maintaining consistent water quality, it supports a more stable and pleasant drinking water experience.

Can the mixer be installed in existing tank systems easily?

Yes, the mixer is designed for straightforward installation in existing tanks. Multiple mounting options allow it to adapt to different tank types without requiring major structural modifications.
