Construction Options

  • Standard Construction — Steel panels and structural elements are constructed of heavy-gauge G-235 (Z700 metric) hot-dip galvanized steel. Air Inlet louvers are constructed of UV-resistant, fiberglass reinforced polyester (FRP).
  • Optional Thermosetting Hybrid PolymerA 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 available. 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.
  • 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.

Prime Surface Coil Configurations

Hot-dip Galvanized After Fabrication

  • 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 of the coil. 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.
  • 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.

Dry Finned Coil Configurations

FINNIED_DRYCOIL

Dry Finned Coil

The standard finned coil is constructed of copper with aluminum fins and further protected assuring long lasting nominal performance. The coil has 6 rows and is available in various serpentine arrangements. The unit flow and pressure drop allowance must be taken into account when the finned coil serpentine is selected to obtain the most suitable HXV selection. Consult your local BAC Representative for selection assistance.

Fan Drive System

High Efficiency Fan

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 exclusive 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 for cooling tower service, and is backed by BAC’s comprehensive five-year motor and fan drive warranty.

Independent Fan Operation

Models HXV-64X and Q64X are provided with one fan motor driving two fans as standard. Models HXV-66X 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, providing an additional step of fan cycling and capacity control.

BALTIGUARD™ Fan System

Baltiguard

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.

Low Sound Operation

HXV_LowSound

The low sound levels generated by HXV Closed Circuit Hybrid Cooling Towers make them suitable for installation in most environments. For extremely sound sensitive installations, factory designed, tested and rated sound attenuation is available for both the air intake and discharge.
