Air cooled heat exchangers (ACHE) or Fin Fans are used extensively in the Oil, Gas, Refining, Chemical, Power and other heavy industries. As a critical component to your production process, maintaining good ACHE performance is essential.
To enhance and optimize the performance of your ACHE, we deliver cooling capacity through a comprehensive portfolio of advisory, maintenance and cleaning services.
Various factors influence cooling capacity with cleaning being just one of the many possible solutions to improve ACHE performance.
As part of our consultative approach, we investigate all possible issues associated with ACHE efficiency including hot air recirculation, the condition of the plenum, fan performance, energy consumption of the fan drive, vibration and noise levels. Once the situation has been fully assessed, our experts recommend the necessary corrective actions to resolve all issues.
We provide monitoring and data analysis to document efficiency gains by measuring the air velocity, plenum pressure differential, temperature patterns and energy consumption before and after servicing.
If cleaning is necessary to restore cleaning capacity, we clean the inside as well as the external tube surface. We use a range of methods to clean the external surface including dry cleaning, foam cleaning and mechanized hydro-jetting.
Internal tube cleaning is performed by automated high pressure water jetting techniques such as tube lancing equipment (TLE). Chemical cleaning can be used to remove hydrogen sulphide (H2S), iron sulphide (FeS) and/or sticky pollutants that present challenges to hydro-jetting applications.
