Greetings,

In my search for info I found this forum and thought I would post and get some thoughts.

We are looking to replace 47 year old York Recip Compressors with Refrigerant oil cooling that are used for Propane Refrigeration.

We had a refrigeration study completed (not much help) that supplied us four budgetary quotes.

1) GEA FES Screw compressor system using water cooled oil cooler.
2) MyCom Recip Compressor system using water cooled oil cooler.
1) York Screw compressor system using refrigerant cooled oil cooler.
2) Vilter Recip Compressor system using refrigerant cooled oil cooling.

Needless to say, 4 quotes, 4 options, and the screw options are quite a bit more than the recip options.

What are your thoughts on the

1) Manufacturers?
2) Screw vs Recip for this application
3) Water cooled vs Refrigerant cooling systems

Our current system is most similar with Vilter option.
Of course we have to weigh the upfront cost of the screw with the maintenace cost of the recips.

Thanks for any advice and feel free to ask for more info if needed.
