DETAILS

DF381 is a film fill system designed to significantly reduce the risk of biological fouling without sacrificing high-performance heat transfer.

DF381 is a bottom supported lowclog log fill configuration. Open, angular cross-corrugations allow debris and biological growth foulant to pass, while providing maximum surface area and turbulence to develop efficient heat transfer. Texturing creates thermal capability improvement with little effect on fouling. DF381 offers low pressure drop in an aerodynamic, durable design.

DF381 is easily adapted to any tower’s configuration. To accommodate for various fill heights and/or desired duties, DF381 may be installed in multiple layers. DF381 fill is thermoformed from .020” thick, UV inhibited, chemically-resistant PVC (polyvinyl chloride). The material is extruded and manufactured to rigid specifications before forming, at one of Marley’s plastics facility.

In service now for over ten years at numerous installations throughout Europe, DF381 is now available globally for any counterflow cooling tower, regardless of a cooling tower’s age, design or manufacturer.
