I hope this is the right place to post this thread.
I recently purchased a used Aquarium Chiller.
It is an inline Aqua-Logic DS-3 1/4hp model.
It didn't perform when I used it the first time, so I found a refrigeration repair shop and took it in. They recharged the coolant and gave it back.
It ran fine for about a week, but then took a dump. I took it in again, and apparently it was low on coolant again.
They charged it full of Nitrogen (250psi) and let it sit 24hrs. The pressure did not drop, and his detection meters didnt pick up any leaks.
So now he is telling me there is no leaks, when obviously there is some sort of leak. I asked if maybe it was a leak that would only show when you run the unit, and he said that wasn't possible.
His solution is to charge it up with more freon and try it again....I dont find that very agreeable because the outcome is likely to be the same, and thats 90 bux down the toilet.
They are super busy over there with commercial accounts, and Im afraid they don't have the time to spend on troubleshooting.
I am hoping one or more of you kind folks can offer some guidance so I can maybe inspire them a little with some possible solutions.
