Construction Options

• Standard Construction – Steel panels and structural elements are constructed of heavy-gauge G-235 (Z700) hot-dip galvanized steel.
• Optional Thermosetting Hybrid Polymer – A 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 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 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 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 5-year leak-proof warranty.
• Optional Stainless Steel Hot and Cold Water Basins – Type 304 stainless steel hot water basins are provided in addition to the cold water basin.
• 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 5-year leak-proof warranty.

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 the Series 1500 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 cooling tower duty fan motor provides maximum performance for cooling tower service and is backed by BAC’s comprehensive 5-year motor and fan drive warranty.

Independent Fan Operation

Models 15296 through 15425 are provided with one fan motor driving two 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.

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^TM 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.

The low sound levels generated by Series 1500 Cooling Towers make them suitable for installation in most environments.

• For situations when one direction is sound sensitive, the unit can be oriented so that the side opposite the air inlet faces the sound-sensitive direction.
• The Series 1500 is also available with a low sound fan or a Whisper Quiet Fan. The thermal performance with either fan option has been certified in accordance with CTI Standard STD-201 .
• For extremely sound sensitive installations, factory designed, tested and rated sound attenuation is available for both the air intake and discharge.
