SUCCESS STORYREVAMP OF AN OTHER BRAND COMPRESSOR TO GUARAN-TEE ITS PROPER FUNCTIONING

The Indian Oil Corp. Ltd. in Haldia, India, had problems with two of its compressors. Without any major overhauls, the two 27-year-old compressors – one operational, the other in standby – were prone to malfunction because of its damaged piston rings, valve plates and springs. Burckhardt Compression revamped the compressor – which included modifying the existing piston and piston rings – to bring it back to proper functionality.
