1. These are suggested arrangements for preliminary layout purposes. Consult your EVAPCO representative or http://www.evapcoeurope.com/ for
factory certified steel support drawings.
2. The recommended support for the AT Cooling Tower is structural “I” beams located under the outer flanges and running the entire length
of the unit. The unit should be elevated to allow access underneath the unit and to the roof below. Mounting holes, 19mm in diameter,
are located in the bottom flanges of the pan to provide for bolting to the structural steel.
3. Beams should be sized in accordance with accepted structural practices. Maximum deflection of beam under unit to be 1/360 of the unit
length, not to exceed 13mm.
4. For these models where two support beams are required, deflection may be calculated by using 55% of the operating weight as a uniform
load on each beam.
5. Beams should be level before setting the unit in place. Do not level the unit by shimming between it and the “I” beams.
6. Support beams and Anchor bolts are to be furnished by others.
7. Dimensions, weights and data are subject to change without notice. Refer to the factory certified drawings for exact dimensions.

Two “I” Beams Required (by Others)
Notes:
Models AT 19-56 through 312-960
1. These are suggested arrangements for preliminary layout purposes. Consult your EVAPCO representative or http://www.evapcoeurope.com/ for
factory certified steel support drawings.
2. The recommended support for the AT Cooling Tower is structural “I” beams located under the outer flanges and running the entire length
of the unit. The unit should be elevated to allow access underneath the unit and to the roof below. Mounting holes, 19mm in diameter,
are located in the bottom flanges of the pan to provide for bolting to the structural steel.
3. Beams should be sized in accordance with accepted structural practices. Maximum deflection of beam under unit to be 1/360 of the unit
length, not to exceed 13mm.
4. For these models where two support beams are required, deflection may be calculated by using 55% of the operating weight as a uniform
load on each beam.
5. Beams should be level before setting the unit in place. Do not level the unit by shimming between it and the “I” beams.
6. Support beams and Anchor bolts are to be furnished by others.
7. Dimensions, weights and data are subject to change without notice. Refer to the factory certified drawings for exact dimensions.
