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.
