6.8 Site Considerations
The drycoolers and pumps should be installed in a location offering maximum security and access for
maintenance.
Avoid ground level sites with public access and areas that contribute to heavy snow or ice
accumulations. Utilize Piggyback drycoolers whenever interior building locations must be used. To
ensure adequate air supply, Emerson recommends that the drycoolers be located in an area with
clean air, away from loose dirt and foreign matter that may clog the coil. In addition, drycoolers
should not be located near steam, hot air or fume exhausts. Drycoolers must not be installed in a pit,
where discharge air is likely to be recirculated through the drycooler or installed where objects
restrict the air inlet free area. Also, the drycoolers should be located no closer than 3 feet (1m) from a
wall, obstruction or adjacent unit (see Figure 111).
The drycooler must be installed on a level surface to ensure proper glycol flow, venting and drainage.
For roof installation, mount the drycooler on suitable curbs or other supports in accordance with local
codes.
Allow adequate space for pump packages, expansion/compression tanks, piping and additional field
supplied devices.
When mounting pump packages, mount on level surface or suitable curbs that will allow cooling
ventilation air to enter from underneath the pump package frame and exit through the louvers.
