Standard Construction:

• Steel panels and structural elements are constructed of G-235 (Z700 metric) hot-dip galvanized steel. Casing panels and air inlet louvers are constructed of UV-resistant, fiberglass reinforced polyester (FRP).

Optional EVERTOUGH™ Construction:

EVERTOUGH™ Construction combines the most corrosion resistant materials to provide the best value in corrosion protection for most water chemistries. Specifically, the following materials are used:

• The cold water basin is constructed with the TriArmor^® Corrosion Protection System. The basin is leak tested at the factory and warranted against leaks and corrosion for 5 years.
• Designated steel components above the cold water basin are constructed of heavy-gauge G-235 galvanized steel and further protected with a thermosetting hybrid polymer.
• The hot water basins are constructed of corrosion and UV-resistant pultruded fiberglass reinforced polyester (PFRP) with corrosion resistant basin covers.
• The casing panels and air inlet louvers are constructed of corrosion and UV-resistant FRP.

EVERTOUGH™ Construction is backed by a comprehensive Louver-to-Louver^SM 5-year warranty which covers ALL components from the fan to the cold water basin, from louver to louver including the motor.

• TriArmor^® Corrosion Protection System – The cold water basin is constructed of the TriArmor^® Corrosion Protection System. The system consists of a heavy-gauge G-235 galvanized steel substrate, fully encapsulated by a thermosetting hybrid polymer and further protected by a polyurethane barrier applied to all submerged surfaces of the cold water basin. The basin is leak tested at the factory and warranted against leaks and corrosion for 5 years.
• Optional  Thermosetting Hybrid Polymer – A thermosetting hybrid polymer coating used to extend equipment life, is applied to select hot-dip galvanized steel components of the cooling tower. The thermosetting hybrid polymer has been tested to withstand 6000 hours in a 5% salt spray without blistering, chipping, or loss of adhesion.
• Optional Stainless Steel Cold Water Basin – A Type 304 stainless steel cold water basin is provided. Seams between panels inside the cold water basin are welded. The basin is leak tested at the factory and welded seams are warranted against leaks for 5-years.
• Optional Stainless Steel Hot and Cold Water Basins – Type 304 stainless steel hot water basins are provided in addition to the cold water basin described above.
• Optional JE PREMIER SERIES^® Construction – Steel panels and structural elements are constructed of Type 304 stainless steel. Seams between panels inside the cold water basin are welded. The basin is leak tested at the factory and welded seams are provided with a 5-year leak-proof warranty. Casing panels and air inlet louvers are constructed of corrosion and UV-resistant fiberglass reinforced polyester (FRP). Each cooling tower provided with the JE PREMIER SERIES^® Construction is backed by a comprehensive Louver-to-Louver^SM 5-Year Warranty, which covers ALL components from the fan to the cold water basin, from louver to louver, including the motor.
• Optional Seismic and Wind Rated Unit – Select steel panels and structural members are upgraded for extreme seismic and wind load applications.

Fan Drive System

The fan drive system provides the cooling air necessary to reject unwanted heat from the system to the atmosphere. The standard fan drive system on the Series 3000 is the exclusive BALTIDRIVE^® Power Train. This BAC engineered drive system consists of a specially designed powerband and two cast aluminum sheaves located on minimum shaft centerline distances to maximize belt life. A premium efficient cooling tower duty fan motor provides maximum performance and is backed by BAC’s comprehensive 5-year motor and fan drive warranty.

BALTIGUARD™ Fan System

The BALTIGUARD™ Fan System consists of two standard single-speed fan motor and drive assemblies. One drive assembly is sized for full speed and load, and the other is sized approximately 2/3 speed and consumes only 1/3 the design horsepower. This configuration allows the reserve capacity of a standby motor in the event of failure. As a minimum, approximately 70% capacity will be available from the low horsepower motor, even on a design wet-bulb day. Controls and wiring are the same as those required for a two-speed, two-winding motor. On some units the standby fan motor can be increased to the size of the main motor for 100% redundancy.

BALTIGUARD PLUS™ Fan System

The BALTIGUARD PLUS™ Fan System builds on the advantages of the BALTIGUARD™ Fan System by adding a VFD to either the pony or the main motor, depending on system requirements. This offers the benefits of additional capacity control and energy savings, along with the redundancy offered by the BALTIGUARD™ Fan System. Alternatively, a VFD can be added to BOTH the pony and main motor, for complete capacity control and redundancy under any load.

Gear Drive System, Close-Coupled Motor

A gear drive system is available as a fan drive option on Series 3000 Cooling Towers. Both the gear drive and couplings are selected with a 2.0 service factor. Gear construction includes a nickel-alloy steel shaft, casehardened gears, self lubrication, and a single piece, gray iron housing. This drive system ships completely installed and aligned.

Gear Drive System, Externally Mounted Motor

A gear drive system with a TEFC motor mounted outside the airstream is also available on Series 3000 Cooling Towers. A non-corrosive carbon-fiber composite drive shaft with stainless steel hubs is selected with a 2.0 service factor. The motor and drive shaft ship separately for easy field installation.

Low Sound Operation

Fundamentals_of_Sound

The low sound levels generated by Series 3000 Cooling Towers make them suitable for installation in most environments. For very sound sensitive installations, the Series 3000 is available with low sound fan options that significantly reduces the sound levels generated from the tower with minimal impact on thermal performance. The cooling tower thermal performance with the low sound fan has been certified in accordance with CTI Standard STD-201. For extremely sound sensitive installations, most units are available with the Whisper Quiet Fan option to further reduce sound levels. In addition, factory designed, tested and
rated sound attenuation is available for both the air intake and discharge of Series 3000 Cooling Towers.

Basinless Unit

The basinless unit construction option enables Series 3000 Cooling Towers to be directly installed on new or existing concrete cold water basins. This custom feature reduces maintenance costs by eliminating the integral basin from traditional units. It simplifies piping and pumping requirements of multi-cell installations and provides a cost-effective solution for many field-erected cooling tower replacement projects.

EASY CONNECT^® Piping Arrangement

This BAC option simplifies water inlet piping on the Series 3000 Cooling Tower. This piping arrangement automatically balances flow within each cell, eliminating the need for flow balancing valves. A single water inlet connection, located on the side or bottom of each unit, eliminates the need for overhead piping and piping supports.
