DF254 Cooling Tower Fill

DF254 is high-performance, low-clog cooling tower fill.

SPX has unveiled its new DF254 cooling tower film fill. DF254 is a counterflow fill system designed to significantly reduce the risk of biological fouling without sacrificing high performance heat transfer.

Recently installed in Mirant Mid-Atlantic’s Chalk Point Generating Station Unit 4 cooling tower and AEP’s Amos station, increased performance translates to increased revenues from their power plant production.

DF254 is a bottom support low-clog log fill configuration. Open, angular crosscorrugations 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.

Fill Installation at Chalk Point

DF254 is easily adapted to your 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.

DF254 is now available worldwide for any counterflow cooling tower, regardless of a cooling tower’s age, design or manufacturer.

Suggested Specifications

Construction and Materials

• The fill must be film type, constructed of multiple sheets of thermoformed PVC. Each sheet must contain a pattern of angular cross-corrugations to develop the necessary heat transfer capabilities. Alternate reversal of corrugation angularity on adjacent sheets will establish the fill sheet spacing.

• Fill shall be designed to be bottom-supported with a minimum number of supports.

• Fill Depth (air travel)

• The fill depth will be chosen to provide the proper thermal performance. To accommodate for various fill heights and/or desired duties, the fill may be installed in multiple layers.
