Why aren't these compressors popular ?

I wonder what triggers the power on and off the the wound coil?

If you're powering it from a standard AC power source you don't need any type of controller, it will run at 60 cycles per second, just like the AC frequency.

Why don't solenoid valves do that then? Aren't they pretty much the same thing except out in the open?

Wait a minute: say the piston stroke was just 1" long. That would have the piston covering over 430,000 inches every hour. Which is over 80 MPH. <g>

Are you sure that's the operating speed on 60 cycle power supply?

Nope! I'm wrong - it's not even 7 mph. I forgot the 12 to get down to feets.

Sorry about that. <g>

The company claims that they last for decades - with some still running since the 1960's.

Where did you get the information that they only last a few months?

Bought the norcold . POS.

I thought this looked cool, haven't seen one in real life yet...

They sound expensive.

I went to a training seminar on those a couple years ago. Got to play with one that was cut open so we could spin the compressor by hand... Then I never really had to work on one, though I've seen them in operation. They're extremely quiet. You hear a little compressor whine and the refrigerant rushing through the system. They make for very quiet mechanical rooms.

They're definitely expensive, but they're also extremely energy efficient. It's a tough call for a lot of companies between a turbocor compressor and a screw. Screws are cheaper, turbocors are more efficient. If the turbocors were a little cheaper I think we'd see a lot more of them out there. I wish there were more of them out there. They sure are easy to be around while in operation.

Or more probable is Engel can't find a company willing to make them since their engineers didn't design it.

I had 2 of these swing motors on a Norcold fridge in my boat. First one lasted 15 yrs other 20 yrs. It was cheaper to buy a new fridge then replace compressors.
