Inside America's water storage tanks there's a revolution going on

Performance Testing
“Carollo Engineers evaluated the PAX Water Mixer in potable water reservoirs varying from 1 to 4 million gallon capacity. These tests demonstrated that the PAX-designed impeller surpassed conventional mixing technology performance. For example, in one 4.0 MG reservoir, the PAX impeller reduced temperature stratification from 4 degrees Celsius to 1 degree Celsius in just two days using only 100 to 150 watts of power. By comparison, the tank using conventional, continuous mixing still had nearly 3 degrees of thermal stratification under the same conditions.”

Active Mixing - The Solution to Residual Loss

PAX Water Mixer - A Solar or Grid Powered Water Circulator

The PAX Water Mixer is an active submersible mixing system. The mixer easily installs in hours without draining the reservoir, and mixes on-demand to rapidly eliminate stratification, uniformly distribute disinfectants and prevent conditions favorable to nitrification. In addition, the need for on-site chemical addition may be significantly reduced, and when such practices are required, dispersion times can be minimized.

All immersed materials comply with NSF/ANSI Standard 61 requirements for materials in contact with drinking water. All electrical connections are certified to UL standards for maximum safety.

The illustrated on the left shows stratification within a tank that can negatively impact water quality. The second illustration depicts a typical Mixer installation and the strong axial jet of fluid the patented impeller generates. This stream sets up a low-friction, energy-efficient, and stable flow structure throughout the entire volume of the body of water, maintaining completely mixed conditions.

PAX technology replicates nature’s convection current geometry—the same flow structures that are found everywhere from heat rising in a coffee cup to thermal currents in the atmosphere. Nature uses this approach exclusively because it is the most effective and energy-efficient method of mixing fluids. PAX has reverse engineered this natural strategy and patented mixers that achieve the same benefits.

Elevated tank solutions

The PAX Mixer can effectively mix elevated tanks - even with a central riser or support post in the tank. The power of the mixer allows it to be offset slightly from the middle of the tank, and still provide a complete mix. Whether the tank is 100,000 gallons to 2.0 million gallons, the PAX Mixer has been installed in multi-legged, spheroid, and hydropillar style tanks with the same results.

Solar Power System Option

The PAX Water Mixer Solar Power unit is available in three different configurations to meet individual customer needs: solar panel direct, solar panel with grid power back-up, and solar panel with battery back-up for remote off-grid installations. The solar power configuration is fully customizable according to storage volume, location, and solar insulation.

Warranty

The PAX Water Mixer comes with a full two (2) year warranty on parts and one hundred twenty (120) days on labor for installations completed by approved installation contractors. Warranty does not cover damage due to: (i) lightning, flood or other acts of nature, or failure of or inappropriate application of peripheral devices including lightning or surge protectors; (ii) negligence of Buyer or any third party; (iii) vandalism or any other misuse or mistreatment of the product; or (iv) installation by non-licensed contractor.
