The mixers are working as advertised!
We installed the GS-9 ourselves. Very complete kit. Great instructions!
The levels of chlorine residual have become more consistent after installing the GS-12 mixer.
We presented the data to the Board last week and the City is very pleased with the results of the GS-12.
After installing the GS-12 mixer, I was able to keep the tank full during the winter with no icing problems.

The Gridbee® GS Series was developed specifically from Customer observations in the field. It pulls direct flow into the end of the machine and discharges through 3 long slots on the top. Direct flow leaves the mixer as a “vertical sheet” of water while also dragging induced flow water up from the bottom of the tank.


Most importantly, it gives a floor to surface complete tank mix which gives you consistent disinfectant contact and residuals.
