CentraFill – A revolutionary Cooling Tower Fill Splash & Film Heat Exchange Medium with great efficiency

The CentraFill® cooling tower fill consists of predetermined layers of triangle corrugated profiles. The triangle bars are in cross section towards each other in the tower structure.


  • The extreme labyrinth functions due to the positions of the corrugated profiles the air is intensely turbulated in the infill structure.
  • The very open structure of CentraFill® cooling tower fill results in extreme low pressure drop and energy consumption.
  • In the same time the water droplets do attach to the profiles and free fall randomly down to lower levels were it is adhesively spread over the profile angles.
  • The large holdup time of the water in the tower, and the intense contact with the surrounding air, creates an efficient exchange of the heat load.
  • The infill is completely assembled at the cooling tower site. No tools or adhesives required.


  • Standard material is PVC or ABS, PE or PP for special applications.
  • Supply CKD (complete-knock-down) for assembly at the tower site.
  • Box Sizes (SI-mm/IMP-foot): 1200 x 1200 / 4 x 4 – 1800×1800 / 6 x 6 – 2400×2400 / 8 x 8 Height: N6 = 600/2 – N9 = 900/3 – N12 = 1200/4 Combinations of N6+N9, N9+N9, N6+N12, N9+N12, N12+N12, depending on heat load.
  • Thermal calculations and selections on request.
