C.2. WATER DISTRIBUTION SYSTEM
Water distribution is accomplished by a non-rotating, low pressure spray nozzle system and gravity nozzles
pan, designed to provide a uniform water distribution over the ll media and copper coil (as shown in Figure
C-6). Take in account the following recommendations:
▪ The operating ow rate of the Closed Circuit Fluid Cooler must be as close as possible to the design
ow rate. A different parameter, whether lower or higher, will affect the Closed Circuit Fluid Cooler
performance.
▪ The normal operation range of spray nozzles is 2-10 psi. REYMSA recommends maintaining water inlet
pressure between 4-8 psi to achieve a proper water distribution. Operation below this range will cause
the nozzle to produce smaller than expected spray cone, lowering ll´s performance. Operation of the
nozzle above this range may cause ow-induced vibration, which can contribute to nozzle blowout from
the pipe adapter. Both conditions will negatively affect Closed Circuit Fluid Cooler performance. Never
operate the nozzle continuously at pressures over 10 psi.
▪ Verify there are no obstructions in the gravity nozzles pan.
▪ If a VFD is installed, set the VFD to control the Closed Circuit Fluid Cooler fan to the desired process
water temperature.
▪ Never operate temperatures above the allowed level for each material; failure to do so may result
in damaged to the internal components. Refer to Table C-1 for the Maximum Continuous Operating
Temperatures of the materials REYMSA uses for its ll media.
