Burckhardt Compression was selected to modernize MOL Petrochemicals' other brand hyper compressor at its LDPE plant in Tiszaújváros, Hungary. Based on its many years of experience, Burckhardt Compression is capable of developing comprehensive solutions that are compatible with the given framework of any compressor.
The project scope included the high-pressure packing, plungers and central valves for second-stage cylinders to be installed all under the supervision of a highly qualified Field Service Representatives team.
Burckhardt Compression really provided a comprehensive solution of great value to us. After they assessed our hyper compressor we received a detailed report with replacement and upgrade recommendations. Since the compressor modernization, our system availability has increased significantly.
