Superior Cross Flow Technology Explained
Comparing to traditional powerheads and wavemakers, based on propeller nozzle technology, our latest gyre generator is based on crossflow technology.
Crossflow Technology
Cross Flow Technology
- Virtually no dead spots.
- Evenly distributed flow rate throughout the entire aquarium.
- Water bounces back from the other side to create a full circulation.ie.generating "gyre flows".
Propeller Nozzle Technology
Propeller Nozzle Technology
- Dead spots with relatively poor water movement.
- Very strong flow in the center,making coral placement very difficult.
- Very weak flow near the other end of the aquarium.
Near-Silent Operation With Sine Wave Technology
Sine Wave Pattern
Electricity current alternates in a much smoother pendulum while using Sine Wave Technology
Sine Wave Technology Decibel Level
Traditional Pattern
Electricity current alternates in a very sharp pattern while using traditional Technology
Traditional Technology Decibel Level
Achieve full circulation within the aquarium with ease
