Increased System Efficiency after Revamp of Other Brand Compressor
After the breakdown of an other brand process gas compressor (make-up), the Indian Oil Corporation Ltd Refinery in Panipat, India, contracted Burckhardt Compression (BC) to carry out a compressor revamp as a local service partner. The refinery was running at high risk, with only a single stand-by compressor in operation. In order to avoid a complete plant shutdown, a reliable solution had to be found and fast.
“After the revamp, our compressor has operated to our full satisfaction without any issues. We appreciate
Burckhardt Compression’s rapid response, the
superb quality and high safety standards of its work.”Shridama Yadav
