SPX Cooling Technologies manual Marley Reflex RTM Fan Cylinder, Sp-Rtm

/ Marley Reflex RTM Fan Cylinder /

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.
