▪ Place the Closed Circuit Fluid Cooler where it will have at least the recommended clearance on all sides
for servicing and for adequate air intake. It is important to consider that the top of the tower should be
above the rooine of any adjacent building or other nearby obstructions. This will limit the possibilities
of the air recirculation back into the towers air intake (See Figure A-2).
Use prevailing summer winds as a guideline for placing a tower in a location that minimizes interference.
▪ Do not place the Closed Circuit Fluid Cooler near exhaust fans or air intakes.
▪ Do not place the Closed Circuit Fluid Cooler near air make-up units where there is a possibility of the
moist tower discharge air mixing with the air being drawn in by it.
A.1.2. ENVIRONMENTAL AND SAFETY
▪ Installation of Closed Circuit Fluid Coolers must be carried out strictly in accordance with all applicable
electrical, safety and construction standards as well as state and local standards and codes.
▪ Before proceeding with the installation, make sure the area is provided with a grounded power source
supplying the correct voltage (required by the motor and pump). Field wiring should be completed
by qualied personnel. All electrical wiring should comply with the electrical codes. Also see section
“A.3.3. WIRING”, for proper wiring.
▪ Place the Closed Circuit Fluid Coolers on a leveled structural surface, capable of supporting the
operational weight of the tower. Refer to section “A.3.1. LEVELING AND TOWER SUPPORTS” of
this manual for more information about leveling and recommended support. Contact your REYMSA
representative with any questions regarding the recommended support for the Closed Circuit Fluid
Cooler.
▪ REYMSA Closed Circuit Fluid Coolers are industrial equipment with rotating parts. Care must be taken
to install them in a safe area whose access is restricted only to authorized personnel.
▪ Locate the tower where there is a safe access for its maintenance.
▪ The Closed Circuit Fluid Cooler must be installed in a location where the tower’s discharge air cannot be
drawn into any surrounding building fresh-air ducts.
▪ There is a certain amount of water that can be carried over in the discharge air of all Closed Circuit
Fluid Coolers (drift). Consideration should be given to placing Closed Circuit Fluid Coolers away from
high trafc areas such as entrances and parking lots.
