DF254 Counterflow Film Fill

Overview
DF254 is a film fill system designed to significantly reduce the risk of biological fouling without sacrificing high-performance heat transfer. DF254 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.

Features


Highlights:
  • High-performance low-clog design
  • Bottom supported
  • Requires minimum number of supports
  • Log configuration

DF254 is a film fill system designed to significantly reduce the risk of biological fouling without sacrificing high-performance heat transfer.

DF254 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. DF254 offers low pressure drop in an aerodynamic, durable design.

DF254 is easily adapted to any tower’s configuration. To accommodate for various fill heights and/or desired duties, DF254 may be installed in multiple layers. DF254 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.
