Reflex RTM fan cylinder with access hatch opening
Access hatch designed for ease of use and sufficient 
size to allow removal of mechanical components
The RTM process has smooth texture on the 
interior as well as a smooth gel coat surface 
on the exterior
The fan cylinder does far more than 
protect operating personnel from a 
rotating fan. It is a vital link in the chain 
of critical components that contribute to 
the overall efficiency of the cooling tower. 
When correctly designed, manufactured 
and applied, it assures that the fan will be 
capable of moving the maximum amount 
of air through the tower at the minimum 
required horsepower. Poorly designed or 
utilized, it contributes virtually nothing to 
the fan’s capability and, in some cases, 
can be more of a hindrance than a help.
Velocity recovery, particularly in large fan 
cylinders, is vital to overall fan efficiency. 
It is accomplished by a gradual increase 
in the diameter of the fan cylinder above 
the fan. This reduces the throughput 
velocity of the air—relieving the fan of the 
unproductive work required to maintain 
an unnecessarily high level of kinetic 
energy in the exiting air stream. Specify a 
maximum flare angle of 12° for recovery 
cylinders. Specify a maximum assumed 
velocity recovery of 75% of the difference 
in average velocity pressure, unless 
scale model data for the exact fan and 
cylinder system can be submitted. Specify 
a removable access hatch of sufficient 
size to allow removal of all mechanical 
equipment components.
Marley Reflex RTM fan cylinders have all 
the dimensional and airflow characteristics 
of legacy Reflex cylinders, which allow 
segments to be intermingled with legacy 
parts on partial cylinder replacements.
