Paddlewheel aerators are the most common type of large pond aerator. These aerators use an electric motor or a self-contained diesel engine to convert the rotation of the shaft into a vertical movement of fluid. The paddles are attached to the hub, which is usually anchored to the bank of the pond.
Some commercial aerators can adjust the depth of the paddles for maximum energy efficiency. Increasing the depth of the paddles increases the amount of oxygen transferred, but it also requires more power. It's also important to have the aerator in the proper position for optimal operation.
If you need to move aerators on a steep levee, you will need a bigger tractor. However, most culturists prefer paddlewheel aerators powered by electric motors. Whether you use a PTO or another power source, a good aerator can provide more oxygen for your money.
A PTO-powered paddlewheel will run at just above idle speed and will need 15-30 hp to operate. They can be used to mix ponds or to provide a current of oxygenated water to fish. But they're not very efficient.
If you're planning on using a paddlewheel in a large pond, it's best to place it in the middle of the long axis of the pond. This will produce two or more circulation cells, and it will also help improve vertical mixing.
Tractor-powered paddlewheel aerators are more flexible than other types of aerators. You can use them for any task, including mixing ponds. In addition, they can be portable. They're great for emergency situations, too. Compared to other aerator designs, they are inexpensive and easy to maintain. When choosing a tractor for this purpose, make sure it has a PTO that has a power rating of 45 to 60 horsepower.
Although the standard aeration efficiency of PTO-powered paddlewheels is low, they can be useful in emergencies. In fact, they're better than other aerator designs.
