[dorian353]

Hi,

All is in the title.

Which is the best manufacturer, new technology, for an hermetic compressor ?
(small power : arround 4kw).

I am looking for THE LAST advanced technology, and not a product already very known

Thanks for your answers

Some idea of what this compressor is to be used for/with might help with an answer.

Danfoss-Maneurop, Tecumseh, Copeland, Bristol, They are all good,
Check their web sites for details.

I know these brands very famous, but sometimes, it existes some brands with advanced technology what are not famous, with better performances.

All theses brands are concurrent, thus their product are similar.

May be you know an other !! with special gaz, technology ... I need the best EER

dorian353,
I don't know if they are commercially available especially that size.
The only reason I know something is that they are in newish LG refrigerators &
on there site it tells you how efficient etc they are.
