Since the new installation , energy consumption is on track to fall by 6 ’ 200 kWh per day
The HST technology is designed for exceptionally high reliability in demanding process applications .
two final turbo compressors have also been installed and commissioned .
Since their installation , the new HST compressors have been quietly and effectively performing their role . For the Linz- Asten maintenance team , that ’ s exactly what they wanted . With no temperamental blowers to look after , they can focus their efforts on performance , efficiency and reliability improvements elsewhere on the site .
The greater energy efficiency of the HST units has had a significant impact on energy costs . Energy consumption at the site is on track to fall by more than 6200 kWh per day . Combined with the maintenance cost reductions , that should save the facility around EUR 175 ’ 000 per year , while reducing annual carbon emissions by more than 580 tonnes .
The new blower house and pipework were designed to accommodate six HST40 units , with four installed during the initial phase of the project , to be operated in parallel with two of the existing blowers . That approach was chosen to enable a smooth transition to HST technology . To accommodate for the old blowers , which were slower to reach full speed , some smart adaptations to the control systems were made to ensure that they would operate in sync with the faststarting HST turbo compressors .
AN EASY SWITCH The installation proceeded according to schedule and the four HST compressors were brought into operation with the changeover from the old blowers taking just 10 hours . Following on from this , the
Over recent years , annual maintenance costs for the legacy compressors has reached EUR 40 ’ 000
