When it comes to life support systems, protecting your equipment is just as important as maintaining water quality. That’s why Aquatic Equipment and Design is now offering the CoolBLUE Rings® + NaLa® package—an integrated solution designed to prevent bearing failure and extend the life of motor-driven systems.
Why It Matters
Motors used in aquatic applications are often exposed to damaging voltage transients and high-frequency electrical noise, especially when operated with VFDs (Variable Frequency Drives). This electrical stress can degrade insulation, shorten bearing life, and lead to costly, unplanned downtime. The CoolBLUE Rings® work by absorbing and redirecting that electrical interference, drastically reducing motor bearing currents. Paired with NaLa®, the solution helps suppress common-mode noise, protecting sensitive electronics and reducing alarm fatigue across your facility.
Maintenance-Free Motor Protection
What makes this solution stand out is its zero-maintenance, long-term performance—a fact backed by both field data and real-world results from public aquariums and marine centers.
“Initially, I was very skeptical about MH&W's claims regarding their blue rings... But after installing a set on a problematic motor, I was immediately impressed—not just with how easy they were to install, but also their immediate performance.
Three years and over 60 installations later, I can confidently say the results speak for themselves. What really sets these rings apart—aside from the cost and ease of installation—is once they're in, you don't have to think about them again.”
— Chris Cain, Marinelife Center of Juno Beach
And it’s not just about equipment longevity. These systems improve operational stability in ways your team will actually feel.
“As the nerdy bill-payer I can speak specifically to not being awakened in the middle of the night by automation system false alarms… the museum’s LSS team staffers having smiling faces more often.”
— Steven Bailey, Frost Science Center and Aquarium
A Simple Add-On That Delivers
The CoolBLUE® + NaLa® combination is compact, easy to install, and fits seamlessly into both new builds and retrofits. Whether you're managing a public aquarium, research facility, or aquaculture operation, this is a smart step toward long-term system reliability.
