Ethylene glycol antifreeze foaming problem
Ethylene glycol antifreeze foaming problem
(OP)
We use a 30% aqueous solution of ethylene glycol as an antifreeze for our refrigeration system.
However, it was found that a lot of bubbles were generated in the circulating antifreeze.
Is this a problem that originally occurs when a 30% to 40% ethylene glycol aqueous solution is used as an antifreeze?
Is there any solution?

Contaminant could be responsible for foaming, lack of control of Ph is also an indicator.
I would ask support from the supplier of chemicals for your cooling system .
My view.

Our refrigeration system is a newly applied system. We know of no leaks in the system.
When We shook the EG 30vol% solution in a PET bottle, we saw that many small bubbles were formed, and the bubbles disappeared in a short time.
During pumping, It seems to be originally generated, So I'm concerned that the efficiency in the heat exchanger and the generated bubbles would affect the pump.

Weird, from Foaming tendency now we are talking about bubbles, air ingress, vortex!
Real problem or just a fear? Did you check the performance of the unit and what is the result?
