Aero-Tube™ achieves its high energy efficiency in two ways:

1. Due to the number of pores created during our manufacturing process, there is little resistance created when pushing air through the tubing. Resistance equals energy demand. By working with Aero-Tube™, you can use significantly less horsepower when compared with traditional methods of aeration (paddlewheels, aspirators, less efficient tubing).

2. Aero-Tube’s tiny pore size creates extremely small diameter bubbles. The smaller a bubble of air the more efficiently it transfers oxygen into water (more surface area!). Small bubbles also take longer to rise once they are introduced into water. Slower rising, small-diameter bubbles mean more contact with the water and a much higher rate of oxygen transfer.

By creating significantly smaller bubbles, more efficiently, Aero-Tube™ products are able to deliver high rates of oxygen transfer and energy efficiency. The mechanical aerators tested by GSEE Inc., provided from 1.7 to 3.0 pounds (0.8 to 1.4 kg) of oxygen per horsepower consumed, where Colorite Aero-Tube™ aeration tubing yielded from 6 to 8 pounds (2.7 to 3.6 kg) of oxygen per horsepower used in fresh water. In salt water, Aero-Tube™ tubing supplied up to 15 pounds (6.8 kg) of oxygen per horsepower, making it the ideal choice for shrimp and salt water fish aquaculture

Glossary of Terms

1) Standard Oxygen Transfer Rate (SOTR) – Pounds of oxygen transferred to water per hour (lbs O2 /hour). SOTR is measured in clean water when the dissolved oxygen (DO) concentration is zero at all points in the water volume, the water temperature is 20o C, and the barometric pressure is 1.00 atm (101kPa)

2) Standard Aeration Efficiency (SAE) – Standard Oxygen Transfer Rate per unit total power input. SAE is typically expressed as the pounds of oxygen transferred to the water per hour per HP (lbs O2 /hour/HPwire), and is sometimes referred to as SAE Wire. SAE is used as a measure of how efficiently an aerator is transferring oxygen.
