Construction Options

  • Standard Construction Steel panels and structural elements are constructed of G-235 (Z700 metric) hot-dip galvanized steel.
  • Optional TriArmor® Corrosion Protection System The cold water basin is constructed of the TriArmor® Corrosion Protection System. The system consists of a heavy-gauge G-235 galvanized steel substrate, fully encapsulated by a thermosetting hybrid polymer and further protected by a polyurethane barrier applied to all submerged surfaces of the cold water basin. The basin is leak tested at the factory and warranted against leaks and corrosion for 5 years.
  • Optional EVERTOUGH™ Construction EVERTOUGH™ Construction combines the most corrosion resistant materials to provide the best value in corrosion protection for most water chemistries. Specifically, the following materials are used:
    • The cold water basin is constructed with the TriArmor® Corrosion Protection System. The basin is leak tested at the factory and warranted against leaks and corrosion for 5 years.
    • Designated steel components above the cold water basin are constructed of heavy-gauge G-235 galvanized steel and further protected with a thermosetting hybrid polymer.
  • Thermosetting Hybrid Polymer A thermosetting hybrid polymer coating used to extend equipment life, is applied to select hot-dip galvanized steel components of the 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 Water-Contact Stainless Steel Cold Water Basin A cost effective alternative to an all stainless steel cold water basin, all critical components in the cold water basin are provided in Type 304 stainless steel. The remaining components are constructed of the base material of construction (galvanized steel or a thermosetting hybrid polymer). Seams between the panels inside the cold water basin are welded. The basin is leak tested at the factory and welded seams are provided with a 5-year leak-proof warranty.
  • Optional Water-Contact Stainless Steel Construction A cost effective alternative to all stainless steel construction, all components that are exposed to the recirculating water are provided in Type 304 stainless steel. The remaining components are constructed of the base material of construction (galvanized steel, or a thermosetting hybrid polymer).
  • Optional All Stainless Steel Construction Steel panels and structural elements are constructed of Type 304 stainless steel.

Coil Configurations

  • Standard Serpentine Coil The standard refrigerant 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.
SerpCoil

Serpentine Coil

  • Optional Extended Surface Coil Coils are available with finning 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. 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 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 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).
  • Subcooling Coils Subcooling 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 Coils The 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. 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.

Independent Drive System

Independent Drive System

The fans, motors, and drive system of the VCA are located outside of the moist discharge air stream, protecting them from moisture and icing, while facilitating maintenance.

  • Fans are supplied with dedicated motors
  • Minimum L10 bearing life is 94,000 hours
  • Premium efficient/inverter duty motors are standard
  • Motors meet NEMA Standard MG 31, Section IV, Part 31
  • Dual drive option is available for retrofit applications to avoid costly rewiring

Extended Lubrication Lines

Extended Lubrication Lines

  • Extended lubrication lines with grease fittings located outside the fan section for lubrication of the fan shaft bearings are standard on VCA Evaporative Condensers.

Multiple Refrigerant Circuit Coils

  • Multiple 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.

Copper Sweat Fittings

  • Optional copper sweat fittings are available to simplify field piping for halocarbon based systems.
