I managed to snap a photo of the label on the compressor. It is a Danoss 101Z0200. The attached datasheet for the compressor indicates the capacity of the compressor. The values I've recorded are within the reasonable range of what you would expect for this unit.

How much ice do you go through in a stint and how long is a stint? We use water bottles in ours and refreeze them with dry ice track side. I'm going to try and get a peak at the label on the compressor to see what capacity it is. As the unit is I don't think is practical to put in a race...

Certainly a possibility. The wires are very fine so I would expect the leakage would be minimal. The second unit has just broken through the barrier at around 11 hours to freeze 8.5lbs of water. That indicates a heat transfer rate of around 110 btu/hr. I'm going to let it run a bit longer so...

The initial cooldown of the jugs comes out to 138 btu/hr. Very much in line with the first test.

That is a can of worms. You aren't going to find that any military generators with those approvals. If you require that rating I strongly recommend buying a generator that has it out of the box.

Yea, I'm using the temperature controller for my smoker for this. It is my go-to temperature collection setup. It works great for most things like this. When its not keeping an eye on some texas style brisket its monitoring the temperature of the solar hot water system. Ok. System #2 is now...

Hey Dewie, I'm not able to find when that was added in any of the engine manuals available online. Was that something added for this application or was it a running design change for Yanmar?

I was trying to find examples of the different ones but I didn't make it before falling asleep last night. I'll poke around some more if I have time today.

Sorry I dozed off. The graph shows that it took about 10 hours to freeze the jugs solid. That is in line with the rate of cooling during the initial cool-down of the jugs to the freezing point. If we take 10 hours as the total time that gives us a thermal capacity of the system of ~122 btu/hr...

We're all here to help each other.

That personality trait is for me both a gift and a curse. The unit was running about 14 hours when I started the test. It was at temp (-23c) and running normally.

The top cap is not an oil fill cap. It is a starting aid. You'll need to look in the Yanmar engine manual for instructions how to use it. Recalling from memory you would remove the cap and put a few drops of oil in there if the engine wouldn't get going normally. Always add engine oil to the...

Here are the trends so far. The jugs are just about frozen based on the temperature getting a little noisy. 9hrs is looking like a reasonable estimate based on the calculations during the initial cool-down of the jugs. Once this test is done I'll reset and test the other unit then do one with...

Don't fill the top cap. Fill through the bottom cap where you check level.

That 36" isn't hose length. Its static pressure. Its saying the aux fuel source can't be more than 36" below the pump. If the pump trips the breaker it for certain has a problem. At this point I would take the it off and see if you can get it working on the bench.

The containers have both reached 32 degrees. The trend has flattened out as expected. Looking at the rate of cooling the estimate of about 135 btu/hr is holding up. Assuming this energy transfer rate continues it should take approximately 9 hours to completely freeze 8.5lbs of water. The...

You won't have to prime the fuel line. The pumps are self priming within a reasonable height range. As a general FYI make sure your AUX container is below the generator height as to not siphon into the generator tank and overflow. It shouldn't do that but there has been a few reports of it...

Only being a little sarcastic in response to the tone in your response. I'm more than slightly interested in this kind of stuff. I love this stuff. I'm that kind of geek. And I'm not afraid to be wrong. I've started a capacity test here at the house on one of my units. Photos of the setup and...

I await your results with baited breath.

The temperature inside the unit when you start is not as relevant as you might think. If the unit is empty the only cold is in the mass of the air and the internal parts that have been exposed to that temperature. That stuff is very low thermal mass so if you put something hot in there it will...
