Compressor Revamp to guarantee 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.
„We are very satisfied with the work of Burckhardt Compression. Since the compressor was revamped, its performance has been excellent. Based on the available information and the his own observations during disassembly of the compressor, the field service engineer suggested various modifications to overcome and resolve the existing issues.
Helpful and thoughtful!”Tanmoy Sarkar, Maintenance Manager, Haldia Refinery
