Subcooler Expansion Valves Selection

[afak]

Hi to every one
I need help in how to make selection to expansion valves for sub-coolers used with two stage compressors (Bitzer,Copeland). If there is any manual explain the bases of this kind of selection or software.I will be very thankful.

Have a read of the documents on the Sporlan site.

Follow the compressor manufacturers recommended selection, by referring application details to them.
Other wise warranty will go out the window and you end up with either a cooked compressor or a sump full of aluminium bits/ smashed pistons.
I prefer an external intercooler separator.
