I visited a party and noted that there is a problem, the compressor model no: RF 40C1E-CAV-258 the model is not available in your directory. I want the capacity of the compressor. What are the gases we can able to use for this compressor. I want this compressor for -86CX temperature purpose. Please give me the reply for this and inform to my mail.
