/ Marley Sigma F Series CoolingTower /
The latest addition to the successful Marley Sigma series of crossflow cooling towers utilizes advanced composites and stainless steel for excellent durability and corrosion resistance in a truly cost-effective design.
Drawing on over 40 years of design experience with composites, Marley-designed FRP pultrusions and SMC shapes allow quick, accurate field assembly.
Incorporating many standard and optional features to enhance its appearance, the Sigma F Series adapts equally well to architecturally sensitive campus environments or industrial plants.
Clean Appearance
Lower profile than counterflow; standard internal inlet; optional pultruded casing; optional cased guardrails conceal mechanical
equipment.
Ease of Installation
Consistent, predictable, stable materials offer consistent fit, consistent quality. Multiple casing
options.
Corrosion Resistance
Fiberglass structure, fan deck, and casing and stainless steel hot water basins are impervious to a broad range of corrosive materials; immune
to rot and decay.
Fire Resistance
Optional FRP structural members, casing and fan cylinders are all available with low flame spread
ratings.
No Preservatives
Environmentally friendly. No preservative treatment required.
Stable, High Strength Composite Structure
Less costly than stainless;
more durable than galvanizing; more consistent than wood.
Flexible Operation
Innovative distribution system accommodates wide flow variations
automatically, eases maintenance.
