• Standard Construction:
All steel panels and structural elements are constructed of heavy-gauge Z700 hot-dip galvanized steel. Air inlet louvers are constructed of UV-resistant, fiberglass reinforced polyester (FRP).
• Optional Stainless Steel Cold Water Basin:
A Type 304 or 316 stainless steel cold water basin is available. The critical components in that cold water basin are provided in stainless steel.
• Optional Stainless Steel Construction:
Steel panels and structural elements are constructed of Type 304 or 316 stainless steel.
• 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 2350 kPa.
• Optional Cleanable Header Coil:
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 860 kPa.
• Optional Stainless Steel Coil:
Coils are available in Type 304 or 316 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 2350 kPa.
• Optional Straight-Through Cleanable Coil:
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 860 kPa.
Independent Fan Operation
All FXV-models are standard equipped with the multiple fan motor system. This system consists of an independent fan motor and drive assembly per fan with a plenum partition to allow independent operation of each fan. This standard feature provides 2 steps of capacity control on dual fan units and 3 steps of capacity control on triple fan units, as illustrated below.
Note: When fan cycling is going to be used for capacity control, the unit must be ordered with partitioning panels.
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. For extremely sound sensitive installations, factory designed, tested and rated sound attenuation is available for both the air intake and discharge.
Combined Inlet Shields
Combined Inlet shields prevent biological growth from sunlight, act as a filter for air borne impurities and debris and eliminate water splash out.
