Heat Exchanger Maintenance & Upgrade
Properly maintained and serviced heat exchangers will improve the efficiency of any steam plant by turning unused steam back into hot water which is then recycled by adding it back into the feedwater. Avantis has vast experience in properly maintaining and upgrading many types of heat exchanger. Our teams are capable of deploying to any site globally and presenting smart engineering solutions to operators so they can best maximise the potential of their asset. For outdated and obsolete heat exchangers, Avantis can prefabricate, install and commission new units that are more efficient and cost effective to run.
