Industrial Pond Aerators & Circulators


The Mixer offers incredible pumping rates and is ideal for shallow areas, coastlines, or wherever horizontal flow and circulation is needed. This subsurface industrial aerator is available in a floating (Triton) or submerged (Sub-Triton) configuration.


Otterbine’s Mixer system is ideal for creating horizontal circulation in ponds and lakes to break up stagnant waters or keep shorelines open. Backed by a comprehensive 3-year warranty, check out some of these other great features:

Energy Efficient

Low amperage systems mean less electrical consumption and low running costs.

Proven Performance

Otterbine is the only manufacturer to have oxygen transfer and pumping rates independently tested and published on their aeration systems.


Available in both floating (Triton) and submerged (Sub-Triton) configurations.

Complete Package

Most systems come complete with unit, power control center, and cable with cable quick disconnect for ease of installation.

Shallow Operating Depth

Triton Mixer operates in 3ft or 92cm, while Sub-Tritons require 2.5ft or 76cm of water depth.

Safety Listed & Protected

Package electrically safety tested and listed with ETL, ETL-C. Products for European Union are also safety tested, approved and carry a 3rd party independent CE mark.

Unit Illustration

Industrial Mixer
  1. 1

    Rugged closed cell foam filled low visibility polyethylene float.

  2. 2

    Precision pitched stainless steel impeller is virtually unbreakable.

  3. 3

    Protective arms secure motor unit and allow for easy handling.

  4. 4

    Electrical disconnect is part of upper plate to prevent accidental damage.

  1. 5

    Adjustable brackets allow you to control the angle oxgen is released into the water column. (Sub-Triton models only)

  2. 6

    316 stainless steel cage blocks debris from entering into the units pumping system.

  3. 7

    Enclosed in a corrosion resistant, durable 18 gauge/316 grade stainless steel motor housing, the oil-cooled, efficient 1725/1425 RPM custom built motor has dynamically balanced rotors to move high volumes of water.


The Mixer arrives partially assembled and installation can be performed in just a few steps. Installation varies slightly depending on the configuration ordered; floating (Triton Aspirator) or submerged (Sub-Triton Aspirator).

  1. 1

    Install Power Control Center: Power control center is mounted onshore; a certified electrician is recommended to perform this step.

  2. 2

    Lay Power Cable: Bury/trench power in conduit to pond edge, connect plug to unit.

  3. 3

    (Triton Aspirator) Float System in Water & Moor into Place: A three-point mooring system is recommended. Arrows illustrate the direction of water current. (The use of a boat may be required)

  4. 4

    (Sub-Triton Aspirator) Moor & Secure into Place: Although mounted on the pond bottom, these units should be moored to secure placement. A three-point mooring system is recommended when places in moving water. Arrows illustrate the direction of water current (the use of a boat may be required).

    Maximum Operating Depth for Sub-Triton Models by Horsepower: 1HP = 12ft or 3.5m, 2HP = 21ft or 6.5m, 3HP = 24ft or 7.2m, 5HP = 28ft or 8.5m

Maintenance & Winterization


Otterbine Mixers require minimal maintenance, to insure years of dependable service we recommend the following:

  • 1

    Once a year: Disconnect unit from power and physically inspect aerator, float and electrical cable.

  • 3

    Every three years: An oil change is suggested to keep your aerator running smoothly.


These units can remain in the water during the winter but need to run 24 hours per day to keep the unit from freezing in.
