I'm a researcher working with CO2 since 2005, but only in single stage.
At the moment we are looking for a small two-stage compressor (with maximum swept volume of 6 m3/h). Up to now we have been using Dorin's, however there isn't any compressor of such size available, the ones ready are too big for us.
Does anybody have a TCDH334/4 D or TCDH347/4 D or TCDH334 N-D (Dorin) with can be solt?
