Wilson Heat Exchanger™

CR Series

The Continuous Rotation of the CR Series heat exchangers is being designed for applications where both gas streams are near atmospheric pressure. For higher-pressure applications, consider the IR Series heat exchangers that use a patented indexed-rotation sealing system.

IR Series

The Indexed Rotation of the IR Series is being designed for heat exchange between gas streams with pressure differences up to five bar. For applications with operating flows near atmospheric pressure, consider the CR Series heat exchangers that use a continuous-rotation ceramic disk.

Breakthrough Technology

The ultra-high effectiveness of the Wilson Heat Exchanger™ is the result of MIT research that promises to achieve elusive breakthroughs. The significant benefits of a rotating regenerator-type heat exchanger have long been known but were previously offset by rapid wear and leakage. However, the substantial operational benefits and performance efficiencies of a ceramic regenerator warranted the research to overcome these problems. With worldwide rights to the resulting patented MIT technologies, Wilson TurboPower is currently developing a practical regenerator-type ceramic heat-transfer system for industry.

This ultra-effective, heat-transfer process can achieve a remarkable effectiveness of up to 98%. In contrast to a conventional recuperator-type metal heat exchanger that performs in principle like an automobile radiator, the Wilson regenerator-type heat exchanger uses a ceramic honeycomb disk. As the ceramic core slowly rotates, hot gas flows through and heats a portion of the disk, while cool air or another gas flows in the opposite direction through the remaining preheated portion.

The ceramic core of the Wilson Heat Exchanger has excellent thermal characteristics for regenerators including a low coefficient of expansion, a high working temperature, and low conductivity. The ceramic honeycomb contains between 200 and 1,100 open passages per square inch (depending on the application).

The Wilson Heat Exchanger offers significant advantages over metal recuperators for high efficiency, high operating temperature, high durability, and small size. In contrast to a conventional recuperator-type heat exchanger that transfers heat through the walls of tubes or plates, the Wilson regenerator-type heat exchanger uses a more effective ceramic honeycomb disk. The ceramic core of the Wilson Heat Exchanger can effectively process high inlet temperatures to allow more heat to be recovered and reused. A metallic heat exchanger can suffer severe deterioration at high temperatures, so it is common practice to precool the inlet air or gas — which may prolong equipment life but obviously wastes heat energy.
