Oil Separation System for a Scroll Compressor

Hi everybody!

Could someone explain me how would be an injection system for an oil flooded scroll compressor? Pressures, point of injection, separation system.

I would like to know supliers or manufacturers for that kind of separation systems when we are talking about an organic fluid (could be R245fa), in europe and, also, if is possible, in spain. If not, in USA.

Thank you!

Searching the web would provide some information on suppliers and the equipment that they market.
