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.
