Case Study:
TurboWeb High Efficiency filter resulted in reduction of water wash from every 6-8 weeks to once in 1,5 year
Environment:
Coastal environment and located in an industrial area close to a steel furnace. The North Sea and the location in an industrial area equals high humidity, salty and polluted ambience air.
Location:
- NETHERLANDS
Operation:
Gas Turbine Air Inlet
Turbine name:
GE LM2500
Running hours:
Base Load Power plant running 360 days a year
Type of filter:
Cylindrical /Cylindrical sets with TurboWeb HE high efficiency filter media
Amount of filters used:
256 (128 x 2)
Problem:
- The customer wanted to stabilize Dp and reduce water wash.
- Previous fiters needed water wash every 6-8 weeks, had a life cycle of 2 years and initial Dp of 250Pa. Change out DP was 500Pa.
Solution:
Installation of Nordic Air Filtration’s cylindrical filter with TurboWeb HE High Efficiency filter with coalescer.
