The bacteria we're fighting within the sump thrive best when their oxygen supply is gone. When the machine is shut down for the night, the pump stops circulating coolant, traces of tramp oil float to the surface, and the oxygen supply to the fluid is cut off. This is the best time for bacteria to grow.
Your coolant's health is dependent upon whether it can "breathe". Using an aeration device when the machine pump is shut down is a simple, yet very effective method of keeping bacteria at bay and your coolant healthy.
The Zebra Circulation Pump uses oil-rated tubing and diffusers that will not degrade in our coolant environment.
For sumps or tanks below 100 gallon, use the Zebra Oxygenator or the airpowered Oxygenator.
