Do not use for construction. Refer to factory certified dimensions. This catalog includes data current at

the time of publication, which should be reconfirmed at the time of purchase.

Notes:

1. Data corresponds to all available motors for this model.

2. Operating weight is based on the water level in the cold water basin at overflow height. If a lower operating weight is needed to meet design

requirements, your local BAC Representative can provide additional assistance.

Engineering Data

Notes:

1. * in Model Number below indicates number of cells.

2. For a plan view of Models PT2-1218A-**2 and

PT2-1218A-**T, see Page 5.

3. Nominal tons of cooling represents 3 GPM of water from 95°F

to 85°F at a 78°F entering wet-bulb temperature.

4. The cell will have a break horsepower of 25 HP.

Structural Support

The recommended support arrangement for the PT2 Cooling Tower consists of parallel I-beams positioned as shown on the drawing. Besides providing adequate support, the steel also serves to raise the unit above any solid foundation to assure access to the bottom of the tower. The PT2 Cooling Tower may also be supported on columns at the anchor bolt locations shown in Plan A.

A minimum bearing surface of 12 in2 (77,742mm2) must be provided under each of the concentrated load points (See Note 5). To support a PT2 Cooling Tower on columns with an alternate steel support arrangement, or the optional structurally upgraded unit, consult your local BAC Representative.

Notes:

1. Contact your local BAC Representative for

multi-cell or structurally upgraded unit

steel support.

2. Support beams and anchor bolts to be

selected and installed by others.

3. All support steel must be level at the top.

4. Beam size should be calculated in

accordance with accepted structural

practice. Maximum deflection of beam

under unit to be 1/360 of span, not

to exceed 1/2”. Use 65% of operating

weight as a uniform load on each beam.

The length of the beam must be at least

equal to the length of the basin. Refer to

engineering data for basin dimensions.

Support data and maximum allowed

deflection is tabulated in the table to

the left.

5. If vibration isolators are used, a rail

or channel must be provided between

the unit and the isolators to provide

continuous support. Refer to vibration

isolators drawings for the length of the

rails and mounting hole. Locations, which

may differ from the length and the hole

location of the unit itself.


Structural Support

For replacement installations, the PT2 Cooling Tower has been designed to match the supporting steel of many existing counterflow and crossflow cooling towers without modifications. Shown below are the most common steel support arrangements which can be accommodated by the PT2. IBC wind and seismic load ratings are not available on alternate steel support arrangements. If individual point support is required, or if the steel arrangement is not shown as below, consult your local BAC Representative for assistance.
