Hi colleague,

Here you have a link for a web in Spain where they work a lot with Bitzer industrial applications. As far as I know, oil cooler isn´t needed in those reciprocating compressor. Flash camber isn´t also needed, we use an economizer (plate heat exchanger) to subcool the liquid with evaporation of liquid which is sucked by the compressor in its 2nd stage.
