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