Combining over 80 Years of Cooling Tower Experience
With over 50 Years of Fiberglass Experience
Marley began using composites
in cooling towers in the early
1950s, when they were considered
“exotic materials”. In fact, Marley’s
work with what was then called
GRP (glass-reinforced polyester)
was so extensive that we were
issued a registered trademark
for GRP in 1960. Since then,
commercial formulations have been generically known as FRP
(fiber-reinforced polyester).
Through a process called pultrusion, fiberglass components
can be produced to even higher standards. Components
in the F400 cooling tower meet the stringent
Marley requirements for consistent strength and
predictable performance.
Pultruded structural components are used
throughout the F400 cooling tower to produce an
engineered framework of unsurpassed quality, reliability and
safety. And, the F400’s structural components will always
be available for simple, economic repairs.
