Air Liquide Brazil has purchased and installed a compressor from PDC Machines model number PDC-13-300-3750 for filling tube trailers with helium gas back in 2010. The flow rate was 97 Nm3/hr at 250 bara discharge pressure.
During the installation we needed technical support from PDC Machines. They responded promptly and sent an experienced engineer to assist us. The compressor has been running smoothly since then. It has been running now for 1400 hours without any issues.
PDC Machines has always been prompt in their support when needed. As a result we placed an order for another helium compressor. We expect it to be shipped end of August and on time.
