You might have read or heard the term “degassing”, or noticed that our Cavitek range has a Degas feature. But what is degassing, and why is it important?
What Is Degassing?
Air and other natural gases are found in liquids, especially in water that has come from a pressurised tap. Pouring a liquid solution into an ultrasonic cleaner will also aerate it. You’ll often see bubbles rising to the surface, but there will still be dissolved gas in the fluid that you can’t see.
Why Is This a Problem?
Any air in the cleaning solution will reduce the efficiency of your ultrasonic tank, making it harder to achieve optimal results. The gas disrupts the cavitation process, preventing ultrasonic waves from reaching small cavities and delivering that microscopic cleaning action. In short, the ultrasonic energy during a cycle will be wasted on removing gas instead of cleaning your items.
How Do I Degas the Fluid?
Each time you refill your ultrasonic bath, you’ll need to degas the cleaning fluid. This can be done by heating the solution while running the ultrasonic power. You’ll know the degassing is complete when bubbles stop rising and the surface of the fluid shows consistent ripples. The time required will depend on the volume of your tank. Be sure to degas before placing any parts in the fluid, as they can interfere with the process.
Cavitek Professional Range – Degas Function
The Degas function on our Cavitek range offers a quick and efficient way to remove gases from the cleaning fluid. Its distinct pulse action accelerates the degassing process by allowing bubbles to escape during the pause cycle, making it faster and more effective than standard ultrasonic operation.
