Hybrid Cooling Systems

Optimal solution for plume abatement and water savings

Wet/Dry (Hybrid) Cooling

B&W SPIG environmentally friendly wet/dry (hybrid) cooling towers are the optimal solution for plume abatement and water savings.

Hybrid cooling towers are specifically designed to avoid visible plume in cold, humid ambient conditions and when local constraints require this technology, such as at airports, residential areas, etc.

The main advantages are no plume visibility, cost effectiveness and high performance.

B&W SPIG’s hybrid technology avoids environmental impact by coupling the wet cooling tower with a dry section (heat exchangers). The dry sections are basically conventional air-cooled heat exchangers located in the upper part of the structure above the drift eliminators. The tube bundle designs are commonly triangular pitch with fins.

How Wet/Dry (Hybrid) Cooling Systems Work

Hybrid Cooling Tower - SPIG - B&W



Air enters the tower

Air passes through the wet section

Air passes through the dry section

Air from the wet and dry sections rises and mixes above the fan, resulting in little or no visible plume
