John Crane Launches Gas Seal Technology to Reduce Methane Emissions
19 September 2018
John Crane, a global leader in rotating equipment solutions, has launched its latest gas seal technology designed to be retrofitted into centrifugal compressors with oil seals to significantly lower operating costs, improve reliability and reduce methane emissions by up to 95%.
