Construction Options

  • Standard Construction — Steel panels and structural elements are constructed of heavy-gauge G-235 hot-dip galvanized steel.
  • Optional Thermosetting Hybrid PolymerA thermosetting hybrid polymer coating used to extend equipment life, is applied to select hot-dip Galvanized steel components of the evaporative condenser. 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 Construction — A variety of stainless steel options are available to meet your needs.

Coil Configurations

SerpCoil

Serpentine Coil

  • 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 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.
  • 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 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.

Welding on Coil

  • 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 ASME “U” Stamp Coil — This coil is manufactured and tested in accordance with the ASME Boiler and 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).
  • Subcooling CoilsSubcooling coils are available for those halocarbon refrigerant installations where subcooled refrigerant is specified, or where the pressure drop or a vertical rise in the liquid line is great enough to cause excessive flashing. Standard subcooling coil sections provide approximately 10ºF of subcooling at standard conditions. Subcooling sections are approximately 7” high and are mounted between the coil and basin sections. Coils are hot-dip galvanized after fabrication and pneumatically tested at 375 psig (2,586 kPa).
  • Desuperheater CoilsThe addition of a desuperheater coil can sometimes permit the use of a unit with a smaller plan area. The desuperheater section is mounted on top of the condenser in the discharge air stream. Coils are hot-dip galvanized after fabrication and pneumatically tested at 375 psig (2,586 kPa). Piping between the desuperheater coil and the condenser coil is not included.
  • Multiple Refrigerant CoilsMultiple circuit coils are generally required on halocarbon refrigerant systems, where it is common practice to maintain individual compressor systems. The quantity of circuits, capacity per circuit, and desired connection size should be specified when requesting this option.
  • Auxiliary Water or Glycol Circuit — A circuit can be isolated to provide cooling of a water or glycol loop for compressor jacket cooling. The flow rate and entering temperature should be specified when requesting this option. The leaving temperature should be the same as the condensing temperature.
    When required, orders 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

Series V Fan Drive

Standard Fan Drive System

The fan drive system provides the air necessary to reject unwanted heat from the system to the atmosphere. Dynamically balanced, forwardly curved, centrifugal fans driven by matched V-belts with taper lock sheaves designed for not less than 150% of the motor nameplate horsepower are standard. Cooling tower duty fan motors, custom engineered for BAC to provide maximum performance for evaporative condenser service, are provided and backed by BAC’s comprehensive 5-year motor and fan drive warranty.

BALTIGUARD™ Fan System

SeriesV_BALTIGUARD.jpg

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™ 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.
