B&W SPIG can supply natural draft and both induced or forced draft wet cooling tower systems designed for a wide range of project requirements such as high seismic and wind loads, vibration control, corrosion resistance, low-noise emission, sub-freezing operation and fresh, geothermal, sewer or sea water applications. Cooling tower structures can be customized using fiber reinforced polymer (FRP), precast or cast in situ concrete, steel or wood.
SPIG complies to the main reference codes, guidelines and applicable regulations and customer requirements for the design of cooling plants, to allow safe operation, easy maintenance and energy efficiency.
Mechanical draft field-erected cooling towers are used in a wide range of cooling applications such as power plants, industrial processes, refining, manufacturing and HVAC&R. Mechanical draft cooling towers use one or more large mechanical fans to move air through the tower.
Water is pumped into the tower through a main header and is sprayed over the fill surface. Depending on fan position, mechanical draft cooling towers are classified as either induced draft or forced draft and can be either counterflow or crossflow depending on the relative direction of water and air.
B&W SPIG counterflow cooling towers are designed and configured to meet critical customer thermal performance in a cost-effective manner. Our crossflow cooling towers are designed for lower energy consumption and operating costs while providing ease of inspection and maintenance access.
Power Plant Cooling System
FRP cooling towers have gained acceptance as a smart alternative to wood, concrete or steel thanks to its outstanding properties. FRP cooling tower structures consist of a framework made by structural shapes of fiberglass composite, stiffened with diagonal braces to transfer wind, earthquake and other live loads to the basin. A large area of the fan deck is walkable and designed to allow easy maintenance.
FRP cooling towers are considered the preferred material for harsh and corrosive environments such as oil refineries and petrochemical facilities, offering these features:
B&W SPIG’s environmentally sound cooling towers contribute to safeguarding the delicate marine ecosystem and to reduce environmental impact. Our sea water cooling towers help to preserve costly desalinated water, and also results in reducing the carbon footprint.
When using sea water as make up, material selection is very important. We use corrosion-resistant fiber reinforced plastic (FRP) structures along with high-resistance steelworks and hardware. The mechanical equipment is protected with suitable coatings to provide the highest degree of protection for salt water application.

Sea water hybrid cooling towers
B&W SPIG has also engineered and installed a variety of cooling towers in specialty applications such as hybrid cooling towers (wet/dry), seawater cooling towers, and noise-abated cooling towers.
