Solar Bray Oil

I was wondering what the best way to deal with a Bray Oil system is. We are wanting to remove the oil and replace it with glycol. I have heard of others pumping in glycol until it appears that all of the oil is out. Does anyone have experience with this? Will flushing with a detergent first be a better idea? What's your suggestion in regards to the cleaner used? I have been involved in silicone and bray oil systems, just not with the flushing out part. Any thoughts or suggestions?
Thanks,
Mister T

    Bray oil

    Is this an old Novan system? I installed humdreds of those back in the late 70's and early 80's. Bray oil was good stuff but I don't know where you can get it now. I've changed them over to propylene glycol before by 1st recoving the oil and even blowing it out with a compressor. Then flush with water and then add TSP and run it thru the system on a sunny day by turning on the controller and then flush again. Then charge it with glycol and you should be go to go.

    Solar Flush

    Thanks for the reply Steve. This is what I suspected, but didnt want to do it with asking others their thoughts. How about a silicone system? Have you ever had to flush one of those out? Maybe the same process would work for it, but I have not heard of anyone doing that. Thanks for the imput.
