Trickle Fills

Trickle fills generate thin films of trickling water to maximize cooling in poor-water-quality applications. The advanced flute geometry of these products allows for trickling of water along the structural members to increase thermal performance.

Trickle Fill Features

An image of two horizontal bars, with the top bar labeled "Efficiency" in blue, and the bottom bar labeled "Fouling Resistance" in green. Both bars have light grey sections at the right end, representing a certain amount.

Fouling Resistant

As an alternative to film fills, HTP20 balances high efficiency with fouling resistance.
