Brand of new Alde glycol

in Heating/Plumbing & Winterizing
We are in the middle of changing out out Alde glycol.  We bought what we thought was Rhomer rg rtu 50, but the container is labeled Jeffcool P-150.  The seller says it’s the same stuff but the internet says it’s red.  

I can’t get thru to Truma.  Does anyone know anything about this glycol.

    Not an answer to your question, but can you tell me where you purchased and the cost? Will be following to hear what the group has to say.

    Not the same stuff, as far as I can tell.  I would return that stuff and contact a nüCamp dealer of choice, and get the correct Rhomar fluid from them.  I think going through nüCamp is going to be your best price, from what has been reported here.

    We got the address of a Rhomer dealer in MT from Rhomer website.  It’s Northwest Pipe Fitting in Kalispell.  I was very specific with the sales guy that I wanted Rhomer rg rtu 50.  They said they had a 5 gal container for $185.  So I went to pick it up and made the mistake of not reading the label when the guy loaded it into my car.  It say Jeffcool P-150.  there was no other info other that caution statements,  we haven’t opened it. 

    I called them back today and they said this is the same chemical content a s RHomer and is what they are selling normal commercial users.  Their receipt does say Rhomer rg rtu.

    We have completed all steps (drain old stuff, rinse with water and then distilled water).  It was just then when we noticed different labeling.

    now we’re scrambling to find Century TF stuff since we’re expecting hard freeze this weekend.  No one seems to have the Rhomer in our immediate (driving) area including Nucamp dealer n Missoula.  Instead, I can drive 3 hours to Missoula to get 4 gal of Century for $85 per gal.

    will be calling Truma tomorrow AM in hopes they say the Jeffcool stuff is ok.

    very frustrating, after the drain and rinse went really well.

    Amazon has Century TF 1 stuff for about $60/gallon.

    The fact is: we just don't know.  Truma keeps the ingredients all "secret".  The product described here could be exactly the same as the Rhomar or the Century.  But, we are not allowed to know.

    @Sagiller, are you camping or at home right now.  If at home, just drain all your tanks, drain the Alde hot water and Flo tanks with the yellow pressure relief valves (in the Alde compartment on the floor), and blow out the water lines, to give you a basic wintering job for the upcoming freeze.  This should buy you some time to get the fluid issue sorted.

    @Denny16, His concern is the water in the Alde glycol circuit that has distilled water in it.  Regular winterizing won't protect the glycol circuit.

    @Sagiller, I'm not familiar with the 320 circuit, but can you get to both hoses off the reservoir and use a shop vac to pull the remaining distilled water out?

    To be fair, it's Rohmar that considers two of the ingredients on the safety data sheet "proprietary". It still is 98% propylene glycol and water though. Is it really better than the previous Century TF-1 or did Rohmar merely underbid Century we don't know.

    I called Truma this morning to check on Jeffcool glycol.  I got what I think is a call center person who was going thru script.  She asked me for a ‘product code’ on the container, which I found.  It was 733350.  She said that wasn’t on their list of compatible glycols.  Supposedly the list of code is somewhere on their website. 

    So I got some of Century TF 1 glycol and we just finished the filling of system and testing of heat.  All seems well.   

    An additional issue for us is that we are planning a monthlong trip over Christmas and we will want the Alde to be working as we’ll be boondocking a bit in chilly weather.

    The service guys I talked to at the NuCamp dealer in Missoula did not know much about the changing of the glycol, or why they can’t get Rhomer.   I don’t have much faith in them now for anything nucamp.

    A gazillion thanks to the creator of the great How To pdf.  We had no problems doing all the steps.  A tip we figured out is to run the output (excess) hose outside the camper via the outside shower area.  We could flush everything out into a bucket and not worry about spills inside.
