AIR-COOLED FLUID COOLER
8 • Air-Cooled Condenser Manual
• Isolate this equipment from pressure testing of water, steam, gas and air piping.
• Isolate this equipment from temporary building power.
• The unit must also be protected from damage to the exterior of the cabinet or coil
connections by construction vehicles and personnel.
• Isolate from vibration sources.
• Isolate from direct sun light.
• Isolate from storage of hazardous materials and substances.
• Refrigerant coils have been evacuated and pre-charged with slight nitrogen holding
charge. DO NOT damage or disturb these coils and connections.
• Water coils must have all inlet and outlet connections capped or closed tight to
prevent foreign materials and liquids from gaining entrance during the storage
period.
• When equipment is installed after storage, caution should be taken to inspect and
replace damaged components, if required.
• All moving parts should be hand tested to ensure they are free and clear prior to
start-up.
1.5 Locating the Remote Heat Exchanger
Locating remote air-cooled fluid coolers (i.e., heat exchangers) installation:
• In secure areas offering maximum security.
• Where service is easily accessible.
• Areas where public access is available should be avoided.
• Install in an area with adequate airflow. Remote heat exchangers should be located
in clean areas free from debris or foreign matter that could clog the coil surface.
Avoid areas with loose dirt or other blowing matter which might clog the coil.
• Avoid areas that contribute to ice and snow accumulation. The fluid cooler may need
to be elevated to ensure it is above the snow line in certain regions of the country.
• Avoid areas of hot air or fume exhaust. Remote heat exchangers should not be
located near steam vents.
• Remote heat exchangers located in areas which are exposed to ocean salt air,
industrial or agricultural areas with air pollution should be specified with an optional
coil coating.
• Heat exchangers must be installed on a level surface.
• Mount the heat exchangers with vertical airflow unless the heat exchanger is a
special horizontal airflow unit.
• Remote heat exchangers should not be closer than 36 inches (914 mm) from a wall
or any obstruction. with proper clearance on all other sides.
• With proper clearance on all sides, two (2) units can be placed side by side.
Additional units must be placed at least 48 inches (1219 mm) apart. See Figure 1
Typical Fluid cooler Spacing.
