| Construction Alternatives |
| 1. Optional galvanized and thermal spray coating double protection system |
| The BAC corrosion protection system is a unique system approach to evaporative cooling equipment protection．A special hybrid polymer，formulated for tenacious bonding，toughness，and impermeability to fluid，is applied by electrostatic spray to hot dip galvanized panel and steel surfaces．The polymer undergoes a thermosetting cure process，fuse-bonding to the galvanized steel substrate，which can greatly extend the equipment decorativeness and service life． |
 |
| 2. Optional Type 304 Stainless Steel Construction |
| Type 304 stainless steel Cooling Towers are designed for applications exposed to extremely corrosive conditions or where the longest life is desired．AU steel panels and structural elements，including the structural frames，louver supports，cold water basin，fan deck，and mechanical equipment supports are constructed of Type 304 stainless steel． |
 |
| Optional Cleanable Header Coil |
| For applications that might deposit soluble scale or sludge within the tubes，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 deaning．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． |
|
| Internal Access Options |
| A galvanized steel walkway enables easy access to inspect basin level items such as the pump strainer，make-up assembly，optional basin accessories and provides a dry working area to view the drive system and heat transfer components．An elevated，galvanized steel internal service platform with aluminum ladder provides a permanent working surface for maintenance personnel to inspect and maintain the mechanical system(including fan belts，drive sheaves and motor)．removable drift eliminators and coil section． |
 |
- External Service Platforms
|
 |
|
| Every external platform is preassembled and pre-fitted at the factory to ensure that every component will fit and function exactly as described. The platform will ship secured in the basin and attach quickly in the field with minimum fasteners. Platforms, ladders and safety cages can be added at the time of order or as an aftermarket item.All components are designed to meet OSHA requirements. |
|
|
| Basin Sweeper Pinping |
| Sweeper pinping is an effective method of eliminating debris that may collect in the basin of the tower .A complete piping system, including educator nozzles, is provided in the basin for connection to side stream filtration equipment(by others). |
|
| Extended Lubrication Lines |
| Extended lubrication lines with standard grease fittings are available for lubrication of the fan shaft bearings .Fittings are located inside the plenum area next to the access door. |
|
| Basin Heaters |
| Closed circuit cooling tower exposed to below freezing ambient temperatures require protection to prevent freezing of the basin water when the unit is idle．Factory installed heaters that of basin are a simple and inexpensive way of providing such protection. |
