Technical Field Services

EVAPCO's field engineers are dedicated to helping our customers get the most out of their existing ACC installations through the following services:

  • Optimization of power plant cooling systems & plant output
  • Reconfiguring ACC operating logic to maximize performance and minimize parasitic load
  • ACC thermal performance evaluations (full PTC 30.1 testing or abbreviated testing using plant instrumentation)
  • IR (thermal) imaging to evaluate non-condensable evacuation and potential air ingress issues
  • Sound measurements in the near-field and far-field
  • Airflow surveys to determine module by module airflow of existing units
  • ACC tube bundle replacements
  • Cell additions to increase the condensing capacity of existing units
  • Dry to hybrid cooling system conversion (wet cooling add-on)
  • Wet to hybrid cooling system conversion (dry cooling add-on)
  • Addition of wind screens for wind mitigation
  • ACC air inlet spray systems for performance upgrades during summer
  • Fin tube cleaning systems

CFD Modeling

EVAPCO utilizes state of the art multi-physics modeling software from ANSYS to simulate airside and steamside performance of Air Cooled Condensers.  Our engineers work closely with ANSYS CFD engineers to constantly update and improve our ACC modeling capabilities to provide accurate and fast results for common simulation scenarios such as:

  • Determining recirculation / interference allowances for Air Cooled Condensers
  • Optimizing plant layouts by determining air flow impacts from buildings and equipment located near heat transfer equipment
  • Quantifying ACC performance impacts due to wind
  • Optimizing locations of grade level wind walls and perimeter wind screens for new and existing ACCs
  • Quantifying performance implications of complex ducting arrangements

ACC Spares

No matter who supplied the original Air Cooled Condenser, EVAPCO Dry Cooling can support your ACC spares requirements.  Through strong relationships with key suppliers EVAPCO Dry Cooling can provide spares often at lower prices than going directly to the original equipment supplier.

EVAPCO Dry Cooling can supply spares parts for:

  • Fans
  • Motors
  • Gearboxes
  • Liquid Ring Vacuum Pumps
  • Stream Jet Air Ejectors
  • Rupture discs
  • Vacuum breakers
  • Isolation valves
  • Bypass systems
  • Cleaning pumps
