I thought about making this an email, but other people might be interested so I'll do it in public.

I'm building a simple phase change system, and having aquired most of my parts, I need a direct die evaporator. I'm thinking about converting an MCW6000 for the following reasons:

Very interesting design.
Brazed copper connections
Should accomidate oil return nicely/won't clog easily

However I'm uncertain about pressure. I'm thinking about buying one, brazing fittings over the barbs, and then pressure testing it at a substantially higher pressure then i will use. I'm curious if you can offer any unoffcial ballpark estimates on how much pressure the block will hold before it leaks? Or if you have any comment at all before i try this?

I realize the block may break, but thats acceptable. They're cheap, and I could most likely repair it and use it as a waterblock, or build a heavier top and braze it on.
