Hello

Currently I work over repairing 3 single-stages units:
-vapochill LS
-Prommie mach 1
-LD unit.

Each have been incomplete and/or damaged .

Image

Image

Units were not good packed for shipping .

Image

Vapo LS (the strongest damage :eek:), LD SS and Mach 1.

Image

Mach 1 has been without suction line.

Image

I've started with Prommie
Image

I've removed stock electric.

Image

More pictures soon .

Regards
Peter

Hello Piotres,

Yes, tested it with 280W, approx -30*C with that load .

Image

LD unit before mod.

Image

Image

Image

New black paint . Not powdercoat, just cheap homemade wet acrylic paint.

Image

Leak testing with nitrogen in water .

Image

Image

Holddown must have been moded because I had only versions for 42/54mm evaps, and that one is 38mm.

Image

Image

Image

Image

Also MUCH bigger condenser. New drier, added shrader valve on discharge side.

Image

Image

Image

Image


to sum up .

Now Vapochill LS:

Image

Image

Image

Image

Case has been heavy damaged, so I decide to remove it ...

Image

+remove whole stock electric.

Image

and scrap it ..

Image

That's amount of oil which I've poured from compressor :-O - approx 20 ml.

Image

And that's suggusted amount of new oil.

Image

Now that will be just benching unit on baseplate .

Image

First time I soft-solder captube to accumulator - and I've loved that work .

Image

Pressure testing of whole unit together .

Peter

Final unloaded temperature.

Image

Image

Final 315W load temperature.

Image

We decided to change evap in "unit with LD case"- old wasn't flat .

Image

Image

Plus suction line will be much longer now. Second suction line for another unit (CPU+GPU ).
