Is this condenser parallel flow?

[EarlyPorsche]

I am getting ready to rebuild the AC in my old Dodge truck. Instead of flushing my original condenser, I think I would rather just replace it. If I am replacing it then I would like to get a parallel flow one instead of the stock serpentine. Having trouble figuring out if I have found a replacement on ******** that is parallel flow. The first one is the factory style. The second one is the a bolt in replacement that looks parallel flow to me but I am not sure.

Looks like parallel flow to me.

Thanks. That's what I think I see too. So not only is it the newer parallel flow design but the size of the core is approximately 2" wider and I believe 2" taller too. This should add some cooling?

Neither look like they are parallel flow. They both look to be micro tube serpentine. A true parallel flow should have cylindrical tubes on both sides.

The microtube serpentine is good improvement over the stock tube and fin, and will allow you to flush if catastrophic failure should occur later. Replacement is the only option with a parallel flow if a failure should happen.

Ok so 1 vote for and against.

It does seem to have a tube down one side. The factory one I have is all serpentined tube in and out. Just like the one in the picture. That other replacement has me very intrigued!

Matt is a AC repair professional. I would give his answer more heed.

He might be able to give you a part number for the part you are looking for.

Oh I just noticed you have the same era Dodge as me! So we're in the same boat. I guess no options for parallel flow exist...thinking about brazing one to the my factory mounts and lines. Would this be totally ridiculous?

Hmmm... Matt, what would a real parallel flow condenser look like? From everything I'm seeing online and this portion of the image:


It appears to be. I'm confused too. Thanks.

That condenser shows no cylindrical end on the opposite side to transfer the flow, so I imagine it has to be looped.



EarlyPorsche, you can do pretty much what you want if going so far as to adapt new lines. I don't think it's crazy, it can't be anything but helpful. The only thing I fear about a parallel flow condenser is the fact that I would have to replace it should a compressor send metal through it.

Personally, I would go with a microtube serpentine just for that fact. They work better than the old tube and fin for sure.

Keep in mind, when changing condensers from stock, you will have to account for a change in total system volume. How much depends on what you put in there. 6MM, 5MM? # of rows? It's all relevant.

The second picture is a 6mm expanded tube condenser. Some say they are a step up from the microtube serpentine, I've not played with one. It is not parallel flow.

The part number appears to be Vista Pro (American Condenser) 1036330. Dodge trucks (gasoline) 1981-93.

Awesome! Thanks for the info. I think I am just going to flush out the OEM beast and go with it for now. The one that I thought was parallel flow is made by APDI/PRO with item number 7014387. This is for the 89-93 diesel.

I would not buy anything APDI. In aftermarket condensers, APC or American Condenser (bought by Vista Pro last year) is the way to go.

When I worked as a wholesaler in the automotive heat exchange business, APDI had fit issues, leaks, excessive slag, etc... Bottom of the barrel product.

This link should help anyone who is looking for a condenser. http://www.vistaproauto.com/sites/default/files/2012-13-catalog.pdf This is the American Condenser catalog, as aforementioned, now owned by vista pro.
