Fluid Cooler
Specification Value
Where fluid coolers are installed on an elevated grillage or piers, it is
■
often difficult to get to—and through—the access door conveniently.
This platform provides easy, safe and comfortable access to that door.
This platform provides easy, safe and comfortable access to the
■
access door facilitating inspection of the fill, distribution nozzles and
the underside of the drift eliminators.
If it is your opinion that the control system for the fluid cooler be part
■
of the fluid cooler manufacturer's responsibility, we are in whole-
hearted agreement with you. Who better to determine the most effi-
cient mode and manner of a fluid cooler's operation—and to apply a
system most compatible with it—than the designer and manufacturer
of the fluid cooler?
Marley variable speed drives are
also available for the ultimate
in temperature control, energy
management and mechanical
equipment longevity.
