ESW Closed Circuit Coolers
Method of Shipment
ESW models are shipped with the top section(s) separate
from the bottom section(s). These sections have mating
flanges and will join together in a waterproof joint when
sealed and bolted together as described in the following
instructions. Miscellaneous items, such as sealer tape, bolt
sets and any other required materials, are packaged and
placed inside th0e pan for shipment.
Storage
Do not place tarps or other coverings over the top of the
units if the units are to be stored before installation.
Excessive heat can build up if the units are covered,
causing possible damage to the PVC eliminators, PVC
louvers, or PVC fill. For extended storage beyond six
months, rotate the fan and fan motor shaft(s) monthly.
Also, the fan shaft bearings should be purged and
regreased prior to start-up.
Structural Steel Support
Two structural “I” beams running the length of the unit are
all that is required for support of the units. These beams
should be located underneath the outer flanges of the unit
(see Figure 1). Mounting holes, 19 mm in diameter, are
located in the bottom flange of the unit to provide for bolting
it to the structural steel (see certified print for exact bolt hole
location). Bolt the bottom section to the steel support before
rigging the top section.
Beams should be sized in accordance with accepted
structural practices. Maximum deflection of the beam under
the unit to be 1/360 of the unit length, not to exceed 13 mm.
Deflection may be calculated by using 55% of the operating
weight as a uniform load on each beam (see certified print
for operating weight).
The supporting “I” beams should be level before setting the
unit. Do not level the unit by shimming between the bottom
flange and the beams as this will not provide proper
longitudinal support.
Support beams and anchor bolts are to be furnished by
others. Always refer to certified print for unit weights,
dimensions and technical data.

Rigging Bottom Section
Lifting devices are located in the upper corners of the coil as
shown in Figure 2. The hook of the crane must be a
minimum dimension of “H” above the top of the coil to
prevent undue strain on the lifting devices.
See Table 1 for the minimum “H” dimension. These lifting
devices should not be used for extended lifts or where any
hazard exists unless safety slings are employed under the
section. (See “Extended Lifts” on page 4 for proper
arrangement.) Bolt the bottom section to the steel support
before rigging the top section.
