Cleaning of Air Cooled Heat Exchangers

Air cooled heat exchangers are extremely inclined to external fouling of the fin tubes from pollen, dust, insects, leaves, plastic bags, bird carcass, etc. This reduces the airflow and the heat transfer coefficient, causing deterioration in performance and resulting in lower process efficiency and higher operating costs.

GEA Nilenca - J & W - Cleaning Systems are developed for removing these external fouling of air cooled heat exchangers.

This cleaning exclusively takes place with high pressure water without any additives. The effectiveness of this cleaning technology is so remarkable compared to the known cleaning procedures, such as hand lance high pressure cleaning or fire hose that design data of the heat exchanger can be achieved again.

This is possible by the GEA Nilenca - J & W nozzle beam which is optimally designed for each fin tube geometry with an always constant jet angle. This nozzle beam is linear guided and motor moved. With J & W - Cleaning Systems all known forms of air cooled heat exchangers can be cleaned: 
  • Air-Cooled Condenser (ACC)
  • Flat Cooler
  • V-design
  • Hybrid Cooling Tower
  • Natural Draught Cooling Towers
