Drive System Options

BAC cooling tower duty motors are specially designed for the harsh environment inside a cooling tower and have permanently lubricated bearings, drastically decreasing the maintenance requirement of the motor. BAC belt drive systems are the most maintenance-friendly drive systems on the market, including single nut adjustment to make belt tensioning simple. 

Standard BALTIDRIVE® Power Train-The BALTIDRIVE® Power Train utilizes special corrosion resistant materials of construction and state-of-the-art technology to ensure ease of maintenance and reliable year-round performance.

  • Powerband and two cast aluminum sheaves located at minimal shaft centerline distances, maximizing belt life.
  • Requires only periodic inspection of components
  • Single nut adjustments belt tensioning requires less downtime
  • Suitable for VFD applications without optional accessories

BALTIDRIVE® Power Train Fan System

ENDURADRIVE™ Fan System –The only variable speed direct drive solution for modular cooling towers.

  • Reduces drive maintenance by 90%
  • 100% reliability on transmission components
  • Industry best 7 year motor warranty and 5 year VFD limited warranty

ENDURADRIVE™ Fan System

Gear Drive System, Close-Coupled Motor-A gear drive system is available as a fan drive option on the Series 5000. 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 the Series 5000. 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.

Cold Water Basin

The cooling tower water collects in the cold water basin which provides the required head pressure for the cooling system pump. The Series 5000 cold water basin includes BAC’s patented hygienic cold water basin design. During operation, BAC’s patented hygienic cold water basin helps eliminate any stagnant water zones, which are susceptible to biological growth.

Standard Mechanical Water Level Control-Mechanical make-up valves must operate continuously in the moist and turbulent environment existing within evaporative cooling equipment. Due to this environment, the operation of the valve must be simple, and the valve must be durable. BAC’s high quality mechanical water level control assembly is standard with all units, and has been specially designed to provide the most reliable operation while being easy to maintain. This accessory is omitted for remote sump applications.

Mechanical Water Level Control

Mechanical Water Level Control

Side Outlet Depressed Sump Box –A side outlet depressed sump box is available for field installation below the base of the tower. This option facilitates horizontal piping below the basin, and is a compact alternative to using an elbow in the piping arrangement, saving on both installation time and cost. The outlet connection is designed to mate with an ASME Class 150 flat face flange. 

Low and High Level Alarm float switches-Low and high level alarm float switches are available to provide added control to your equipment operation. Level alarms can alert operators to an abnormal operating condition to ensure the highest system efficiency with minimal water usage.

Multi-Cell Unit Options

Special care must be taken for multi-cell installations to ensure balanced water levels in the cold water basins across cells. If measures are not put in place to ensure balanced basin water levels, a potential exists that one basin may overflow and dump water, while the water level in another tower goes low and requires make-up. This leads to unnecessary water waste. To prevent this from occurring, BAC provides two options for balancing water levels and recommends that the installation be designed to ensure balanced flows to and from each tower.

Flume Box – Standard on all Multi-Cell Units-A flume box is provided as standard for multi-cell units to balance the water level in the cold water basins.

Equalizer –Equalizer connections are available as an option for multi-cell cooling towers in lieu of a flume box. Use of an equalizer allows for easy isolation of a cell for winter operation, maintenance, or inspection while continuing system operation. See “Cooling Towers in Parallel” on page J167 for more information.

Water Distribution System

The Series 5000 Cooling Tower utilizes a low pump head gravity distribution system with large orifice non-clogging nozzles that requires less pump energy than a pressurized distribution system.

Standard Top Inlet Connections-The Series 5000 comes standard with top inlet connections to each of the hot water basins. Hot water basin covers matching the unit material of construction come in easy to handle sections for easy access and inspection of the distribution system. The use of gravity distribution minimizes pump head requirements and allows for maintenance during unit operation. BAC’s patented non-clog nozzles ensure even flow over the fill area and are simple to remove for maintenance.

Standard Weir Dams-Reducing water flow through a unit below the recommended level may potentially create uneven water distribution through the heat transfer section, causing scale build up, splash out/drift, and icing. To successfully modulate the water flow while avoiding potential complications, weir dams may be installed in the hot water basin. With a weir dam, the hot water basin can accommodate a flow range of 50% to 100% of the design flow.

ENDURAFLOW Heat Transfer System

Superior low clog performance for dirty water applications, reduces fill replacement and downtime.

  • Patent pending technology-Maximizes thermal performance in demanding power and process applications
  • Accessible design-Allows for cleaning while tower is in operation, reducing downtime
  • Line of sight cleanability-Reduces maintenance to ensure thermal performance and uptime

Capacity Enhancement

The need to enhance the capacity of a unit may be necessary when layout is restricted or if capacity requirements have increased and exceed an existing unit’s capabilities. By enhancing the capacity of a unit, it may be possible to use a smaller foot print while still meeting thermal requirements of the installation.

Velocity Recovery (VR) Stacks –A VR stack is a conical fan cowl extension that reduces the discharge pressure the fan has to work against, allowing the fan to move more air for the same energy input. By moving more air through the same unit, the cooling capacity is increased without increasing horsepower or footprint. Effectively, the amount of energy required for each ton of cooling capacity is reduced. VR stacks are factory assembled, CTI certified, and can be configured during initial unit purchase to reduce energy requirements or through the aftermarket to increase capacity.

Shipping and Rigging

BAC units are factory-assembled to ensure uniform quality with minimum field assembly. Each unit has been designed with rigging and assembly
in mind and includes features to minimize the number of tools required and installation time.

Standard Rigging Guides-Rigging guides allow for the upper and lower section of units with a two piece rig to align and engage. The guides ensure proper placement
of the top section for multi-cell installations, making rigging much simpler and reducing the time required. This is especially critical
during multi-cell installations when units are rigged side-by-side.

Rigging Guides Ensure Alignment

Knockdown Units –Knockdown units are available for jobs where access to the cooling
tower location is limited by elevators, doorways, or similar obstacles, where lifting methods impose very strict weight limits, or where the shipping cost of a fully assembled tower is excessive. Welded stainless steel cold water basins and TriArmor® Corrosion Protection System cold water basins are excluded.
