• Optional Stainless Steel 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 five-year leak-proof warranty.
• Standard Serpentine Coil - The standard cooling coil is constructed of continuous lengths of all prime surface steel, hot-dip galvanized after fabrication (HDGAF). The galvanizing is on the outside surface. The coil is designed for low pressure drop with sloping tubes for free drainage of fluid. Each coil is pneumatically tested at 375 psig (2,586 kPa) and is ASME B31.5 compliant.
• Optional Cleanable Header Coil – (available on Single Air Inlet Models) - The cleanable header tube bundle provides removable cover plates on the inlet and outlet header boxes to permit access to each serpentine tube circuit for solvent or air-pressure cleaning. Tubes are all prime surface steel tubing formed into a serpentine shape and welded into an assembly. Coil material options include carbon steel coils (hot-dip galvanized outside surface) or stainless steel coils. Each coil is pneumatically tested at 125 psig (860 kPa).
• Optional Stainless Steel Coil - Coils are available in Type 304 stainless steel for specialized applications. The coil is designed for low pressure drop with sloping tubes for free drainage of fluid. Each coil is pneumatically tested at 375 psig (2,586 kPa) and is ASME B31.5 compliant.
• Optional Straight-Through Cleanable Coil - (Available on Single Air Inlet Models) A header box with a removable cover plate at each end of the coil allows access to every tube end for mechanical cleaning or plugging. It is available in carbon steel (hot-dip galvanized inside and out) or stainless steel. Each coil is pneumatically tested at 125 psig (860 kPa).
• Optional ASME “U” Stamp Coil - The ASME coils are requested for heavy industrial or process applications. This serpentine coil is manufactured and tested in accordance with the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, and bears the ASME “U” stamp. ASME coils are hot-dip galvanized (outside surface) after fabrication (HDGAF). The coil is designed for low pressure drop with sloping tubes for free drainage of fluid. Each coil is pneumatically tested at 375 psig (2,586 kPa).

Coil Configurations

When required, coils shipping into Canada are supplied with a CRN. Other coil configurations are available for specific applications. Contact your local BAC Representative for details.

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 all models is the BALTIDRIVE^® Power Train. This BAC engineered drive system consists of a specially designed powerband and cast aluminum sheaves located on minimum shaft centerline distances to maximize belt life. A premium efficient 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 motors and drive assemblies. One drive assembly is sized for full speed and load, and the other is sized for 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^TM 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.

Independent Fan Operation

Models FXV-43X, 44X, Q44X, 64X, T64X and Q64X are provided with one fan motor driving two fans as standard.

Gear Drive System, Close-Coupled Motor

Models FXV-66X, T66X and Q66X are provided with two fan motors driving three fans as standard. The independent fan option consists of one fan motor and drive assembly for each fan to allow independent operation, adding an additional step of fan cycling and capacity control.

Gear Drive System, Externally Mounted Motor

Models FXV-288 and 364 are available with a gear drive system with an external (TEFC) motor. 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.

Equipment Controls

BAC control panels are specifically designed to work seamlessly with all BAC units and engineered to meet your particular application.

Low Sound Operation

The low sound levels generated by FXV Closed Circuit Cooling Towers make them suitable for installation in most environments. For very sound sensitive installations, a low sound fan option is available to reduce the sound levels generated from the tower with minimal impact on thermal performance. The FXV thermal performance with the low sound fan has been certified in accordance with CTI Standard STD-201 . For extremely sound sensitive installations, factory designed, tested and rated sound attenuation is available for both the air intake and discharge.

Whisper Quiet Fan

FXV single air inlet models (FXV-42X through FXV-Q66X) are available with a Whisper Quiet Fan that significantly reduces the sound levels generated from the unit with minimal impact on thermal performance.

Basinless Unit Construction (FXV-288 and 364 Models Only)

The basinless unit construction option enables units 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 replacement projects.
