Captube length for R290

I used a 2cm thick plywood plate as a hold down. It looks ugly but gets the job done I suppose:) On the back of the mobo I used vasoline, armaflex and 4mm thick plastick plate and I could see the ice forming on the plastick...

u could prob use some foam before the plastic

thanx hatemi.
i had a go at trying to make a hold down on the week end, it was much harder than i though it was, i didnt succeed, have to do a little more thinking/planning and try again

also what is better for insulating (best insulator)
neoprene or white foam

Polyurethane is one of the best insulators and with some practice and carfull planing you can use it to insulate the whole evap assy:) I actually tried to use PU foam and molded my whole evap in it but I wasnt very satisified with the results so I tore it apart and used armalfex as an temporary insulation.

Regular styrofoam is usable insulation but its too fragile and soft. I am propably gona use Finnfoam ( http://www.finnfoam.fi/ ) wich is heated and tightly compressed insulation foam. It is propably made from the same material as regular styrofoam but its denser and and therefore better in this particular use. I think I will just cut it to proper dimensions and heat the evap so hot it will start to melt the foam and just press the evap in the foam making a really tight fit:)

I will post some pictures of my first attempt with PU foam in a minute. And after that I 'm getting in bed really freaking fast because today I did a 16 hour day at work and that is quite hard when you have been drunk for three days and barely slept in the whole weekend! Thank god I didn't have hangover taday or else I would have quitted the job...

I used some small pieces of styrofoam on the top of the evap just to keep the hold down at right position before the urethane was dry but it didnt work as planned...This is what it looked like before I sprayed it full with foam:

And here you can see how the foam expands and starts comming out fromm small holes. If the mold is too tight and the foam can't get out, it will brake the whole mold. It expands up to 50% of it's original volume, and it has so much forde it can twist walls and brake window and door frames if applied carelessly. I have even seen it used to lift the foundations of an old house that had silghtly collapsed from one corner!

Wow. I can't wait to see that mounted.

nice stuff i have to find some
dont know where though

oh, lol, very sweet, but how are u gonna mount it?

You can get the polyurethane foam from your local home improvement store i guess.

The mounting is just the regular screws and bolts kinda thing but I will need to get it better and fix the leaking evap. I might aswell just try how well the aspera compressor preforms because I dont trust this Danfoss. I Can hear the valves clicking when its running and it runs so dam hot you cant hold your hand on it even for a second! I'm not sure if it has the propper ammount of Oil in it but as I dont have any oil to add in I cant try. Im going to get some POE oil next month when I get my paycheck so I might aswell trie to change the oil fromm mineral to POE and see If it helps.
