Wow, I never knew they made those for refrigeration use. There's a company that makes low psi air compressors that work the same way and their reliability is light years ahead of the conventional piston compressors. A store I work for has had them on the air supplies for lobster tanks for 15 years now with no maintenance or failures. All the other stores are using more expensive conventional piston compressors that need to be replaced every 5 years and use almost 5 times more power.
Seems like a no brainer for refrigeration use.
Because they're teeny tiny........
Small enough to be powered by a 12VDC or 24VDC power source... Can't even venture a guess, but suspect it's under 2000 BTU's
If it can't chill my beers faster than I can drink them, I want no part of it.
Be sure to update us on the max capacity. I does not impress me too much personally, but then again, who am I?
Isn't that a straw-man argument you are making? <g>
The compressors have one moving part. <g>
The "hours on the starter" has nothing to do with this discussion - which was about why the compressors are not commonly used. You suggested that it was due to them operating on a low voltage, such as 12 or 24 and so having low capacity. "Teeny-tiny" was the descriptive phrase. The reliability was never an issue.
Isn't that a beer cooler in the upper RH corner?
I'd say that's a low capacity unit, like a sterling cooler.
PHM, I believe you are simply misunderstanding where I was coming from.
Being as the starter on your truck has a duty cycle of like .001%, it draws an incredible amount of amperage (read watts) for an extremely short (comparatively) amount of time.
A refrigeration compressor on the other hand has a duty cycle of say 90% if not 100%, which means it would have to draw very little current (again watts). So using this logic, it would have to have a relativity low HP, or small capacity, this compressor seems to have been developed specifically for portable refrigeration equipment. The company seems to be an automotive generator manufacturer.
Not trying to start a major debate, just wanted to make sure my point was clear.
Someone just told me that Engel has a patent on the compressor design and doesn't want to allow anyone else to make them. I guess that would explain why they aren't in common use. I wonder what triggers the power on and off the the wound coil?
