• 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). 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 (2586 kPa) and is fabricated per ASME B31.5 standards.
• 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). 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 335 psig (2,310 kPa).
• Optional Extended Surface Coil: Coils are available with half or all rows finned at 5 fins per inch for seasonal wet/dry operation. The coil is hot-dip galvanized after fabrication (HDGAF). The galvanizing is on the outside surface of the coil and fins. 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 fabricated per ASME B31.5 standards.

Serpentine Coil

When required, coils shipping into Canada are supplied with a Canadian Registration Number (CRN).  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.

Independent Fan Operation

Models FXV-0809, FXV-0812 and FXV-1212 are provided with one fan motor driving two fans as standard. Models FXV-0818 and 1218 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, Close-Coupled Motor

Models FXV-288 and 364 are available with a close-coupled gear drive system. 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

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.

Low Sound Operation

FXV Closed Circuit Cooling Towers generate low sound levels, making 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 is certified in accordance with CTI Standard STD-201.

Sound Attenuation

For extremely sound sensitive installations, factory designed, tested and rated sound attenuation is available for both the air intake and discharge. On single air inlet models (FXV-0806 through FXV-1218) the thermal performance with intake or discharge sound attenuation is certified in accordance with CTI Standard STD-201.

Unit With Intake and Discharge Sound Attenuation

Whisper Quiet Fan

FXV single air inlet models (FXV-0806 through FXV-1218) are available with a Whisper Quiet Fan that significantly reduces the sound levels generated from the unit with minimal impact on thermal performance. The FXV thermal performance with the Whisper Quiet fan is certified in accordance with CTI Standard STD-201.

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.
