Model: 1100
Hi,
I have a VW Vanagon that has been converted to R-134A, and isn't really cutting it. I've done an engine conversion on it with an I4 engine that's basically the same as a circa 1997 Golf/Jetta. I have a Sanden SD7V16, model 1100 compressor on it now, and wonder if anyone can tell me if it's R-12 compatible. It's just labeled as R-134A. The s/n is 1105803620, and it also has the #1HC820803D, and says "Oil: SP10". Any help appreciated.

The relatively large displacement SD7V has a built in override to keep full stroke/displacement while the discharge pressure is high, therefore a monster condenser or gobs of condenser air mass flow or a smaller displacement compressor is required. An auxiliary condenser would need a electric fan.

What would happen if you ran R12 in this compressor? I believe this poster was in the shop asking questions the other day. Already has a large PF condenser and Head pressure was real high. If I remember corre4ctly this Vanagon has a sub-frame blocking air flow. Poster even inquired about a second condenser lying flat with a fan. I have never had a lot of luck with condenser lying flat.

If A/C is converted to R12 properly, by removing SP10 lube and adding Sanden 5GS or DENSO mineral napthenic based mineral oil (not GM or other paraffinic mineral oil), compressor should be OK for chemical compatibility.
The suction pressure that causes the SD7V16 to de stroke would would change based on the temperature verses pressure characteristics of the 2 refrigerants.
