Bought this on Ebay today. Operating range covers any conceivable evaporator size for the 86' early rear a/c in the Vanagon. The JW bulb charge is all purpose and covers from -40 F to 60 F evaporator temperatures and it's internally equalized, no need to braze a fitting on the suction line. Easy to adjust super-heat regardless of refrigerant used. Now need to find a couple of female flare to male O-ring connection adapters.

I have an 86' Syncro Camper and have been looking for a receiver/drier that would replace (the apparently) odd ball original, and fit in the very small space allocated in the left rear wheel well. So far, no luck. So I think I'm going to use a horizontal R/D. Easy to install and access and will be well positioned to receive gravity flow of the liquid refrigerant from the condenser.
Has anyone else tried one of these?

The straight through R/D won't work, just not enough room with the charcoal canister and fuel filter jammed in there too. The existing one is very similar to the one below except that the outlet is not in line with the inlet, it has a not quite 45* angle to it in relation to the inlet. And without that angle I haven't seen a fitting that will immediately angle from the R/D. I just don't want to dangle this thing and hoses farther out into the wheel well.

I could use a little bit more of the physical kind! I agree that relocating the R/D is the easiest way to go. I'm liking the "elegance" of the horizontal R/D, a couple pieces of uni-strut on the left "frame rail", 2 pipe clamps, straight hose connections in and out and a good chance I won't hurt my back.
i think Nostalgic Air's Horizontal R/D, made for street rods etc. may have issues if running your vehicle on sustained steep accents and declines (lots of those here). So taking a page from TK's agricultural machinery background I looked into what's available there. It looks like they use a larger diameter and shortened body on heavy duty "off road" applications to increase the liquid depth. These units appear to be popular with the extreme 4x4 crowd too. Cost still very reasonable at $40.00 or so.
Other than a different TXV and R/D, I'm not doing much that's different from what others have done on their A/C rebuilds. What I'm most curious about is the performance of an HC-12A system with a well adjusted TXV. Not thinking it will be dramatic but interesting to me. |

Ordered this horizontal R/D today, should be here next week. Making the bulk of my hose/fittings purchases on ebay for frugality. Will need to order some fittings and hose from Hose Warehouse or similar to complete the package. If I can get the fittings off my OEM condenser I'll probably keep it in use, unless closer inspection dictates otherwise.

| I'm not 100% clear on the internal workings of this particular R/D, have not seen a cut away view. If I had to take a stab in the dark, I would guess that the liquid refrigerant from the condenser is directed to the upper section of the R/D where it is filtered then the liquid pools in the lower half where a dip tube (attached to the outlet) picks up the liquid and directs it toward the TXV. There may also be a baffle system of some type inside. I'm betting that Parker knows what they are doing, so I won't worry about it too much. |
