A compressor may include a shell, first and second compression mechanisms, first and second motor assemblies, first and second suction inlet fittings, and first and second discharge outlet fittings. The first and second compression mechanisms are disposed within the shell. The first and second motor assemblies are disposed within the shell and drive the first and second compression mechanisms, respectively. The first and second motor assemblies are operable independently of each other. The first suction inlet fitting may be attached to the shell and provides fluid to the first compression mechanism. The first discharge outlet fitting may be attached to the shell and receives fluid compressed by the first compression mechanism. The second suction inlet fitting may be attached to the shell and provides fluid to the second compression mechanism. The second discharge outlet fitting may be attached to the shell and receives fluid compressed by the second compression mechanism.

A computer-implemented method for detecting condensate in an oil system of a compressor, having an inlet and an outlet. The method incudes the steps of: determining the humidity at the inlet and at the outlet or downstream of the outlet of the compressor; determining the amount of water vapor that enters and exits the compressor based on the humidity determined at the inlet and the outlet or downstream of the outlet; determining the amount of condensate that remains in the compressor by determining the difference between the amount of condensate that enters and exits the compressor; storing the amount of condensate that remains; and repeating the aforementioned steps at regular intervals and storing the amount of condensate and how long said condensate remains in the compressor.
