We suffer with oil carry over (a lot > 150l) from our DUOPACK GEA compressors (2 screws on 1 simular oil separator). Anybody the same (bad) expirience with this kinds of Duopack? 1 compressor is fixed speed, 1 with inverter. On NH. Minus 40 / +35°C. OIl Petro Canada Reflo 68A. Like to see a Duopack working without this oil problems, without success so far. Thanks in advance. Carlos.
