Helium Fridge

Anyone get one of the new units this year with a helium Atwood fridge? If you have had an ammonia type any comparisons on performance?

Hydrogen?

The more common Dometic RV refrigerators use Ammonia; not hydrogen...

What make/models use hydrogen?

Correct me if I am wrong but all absorption fridges use hydrogen gas as the component that circulates the ammonia to generate cooling other than the new Atwood.

I believe the only thing in an ammonia system is ammonia.

Keep in mind that ammonia is NH3.

exactly. the fridge HAS ammonia, but by the absorbtion process, and heat create different almagamations of structures during the process.....such as hydrogen and water....so i guess if we wanted to be technical we would say it has N, H, and O....lol...im not well versed in the reaction of a helium fridge..but im interested now!!

Interesting for sure. Going to dig a little more on the Atwood...it appears that it too has ammonia so in theory it may have a hydrogen component as well. They call out an ammonia tube in the patent...how it's configured over the standard design is the key.
