if you need one the filter drier you would add is an 032, or a spun bullet drier, either will work. it goes in the liquid line between the evap and the compressor, you will need 2ea 1/4 male flare nuts
There is some sort of filter looking thing that is already tapped into the high pressure side of the system but it's all soldered in place and does not look serviceable. I'll take a pic and post.Sure but what boat is the Tartan???
You've sorted this out just in time to help me fix the one in the Tartan.
You can show me the cruiser's secret handshake.
I am in the Marine refrigeration biz, let me know what info you need. I get a kick out of helping folks fix stuff.
The soldered thing you see is a bullet drier, they come pre installed on nearly every unit of this type.
They have a lifespan that begins to tick away the first time someone opens the system to the atmosphere.
If the unit gets ANY air or moisture in it, like say a leak on the low side to the point that when its running in a vacuum, its basically pulling air in, then the lifespan is really short, like hours instead of decades.
Once it gets, what we call, "non-condensables" in it, then all sorts of bad things start happening, acids form in the oil as it breaks down, this in turn can screw up the compressor motor windings and can also simply plug the captube.
All in a days work.
So are you saying once the bullet drier fails then the entire system is fucked? Why is the system not designed for that to be a serviceable filter?
Been running like a champ for a week now!
That's great! But the spun driers have only so much to give before they go bad, again, this is 20+years on a good sealed system that hasn't been messed with, like your fridge at home, right?
Marine refrigeration systems are a different deal, flare fittings, quick disconnects, vibration, salt, power issues, lack of cooling on the condenser, these all conspire to age things faster than a normal household system.
It sounds like you guys pulled a good vacuum on it and that is huge, you now have a nice clean dry system,(we hope). You can replace the drier pretty easy if it comes to that, the pressures on a 134 system are such that soft solder can be used, the trick is to not run it when its not dry, or to ignore problems and forcing the unit to run hot.
It might work for years, and it might not....but its working now, which is awesome, so fill it with adult beverages and leave it alone!
