Cleaning technology designed for measurable throughput recovery

Air-Cooled Heat Exchanger (ACHE) Cleaning

When equipment becomes constrained, throughput declines.

RTI’s ACHE cleaning, ReNu, combines patented nucleated foam technology, repeatable operational expertise, and measurable performance benefits. Removing cooling constraints helps facilities restore throughput more effectively, optimize energy consumption, and make more informed operational decisions.

Induced Draft Fans

Atmospheric fouling reduces airflow and cooling effectiveness, forcing induced draft fans to work harder to maintain performance. ReNu restores airflow and efficiency while the fans remain in service.

Forced Draft Fans

Dirty finned surfaces increase system resistance and reduce heat transfer performance. Fans can be isolated individually during cleaning to minimize operational disruption.

Atmospheric fouling can negatively affect condenser performance, increase backpressure, and limit plant efficiency. ReNu restores cooling capacity and heat transfer performance to support generation output and operational flexibility.

Accumulated atmospheric foulants reduce heat transfer effectiveness and increase energy demand. ReNu removes insulating deposits to restore thermal performance and improve process efficiency.

Atmospheric fouling can limit heat recovery and reduce overall plant performance. ReNu restores heat transfer efficiency, helping facilities recover more value from existing operations.

Fouling within convection sections restricts heat transfer and can increase fuel usage required to maintain process conditions. ReNu restores thermal performance, improves efficiency, and supports production targets.

Fouling creates a barrier to heat transfer, reducing energy recovery and increasing fuel consumption. ReNu restores economizer effectiveness, helping facilities maximize efficiency and lower operating costs.

Any finned heat transfer surface exposed to the atmosphere is susceptible to fouling and performance loss. ReNu’s patented cleaning process restores heat transfer performance across a broad range of critical equipment.
