Wilson Heat Exchanger™CR SeriesA Continuous-Rotation regenerator using ceramics technology to improve dramatically the performance of gas-to-gas heat exchange and reduce system sizeThe CR Series is best-suited 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. |

Performance BenefitsHigh effectivenessUp to 98% of the thermal energy can be transferred in a gas-to-gas, heat-exchange process compared to the 40% to 80% typical effectiveness of shell-and-tube and other metal exchangers. High operating temperatureThe ceramic matrix is ideal for high-temperature operation. The standard matrix is capable of operation up to 1,100°C (2,012°F), and alternative matrix compositions are available for heat-transfer temperatures up to 1,400°C (2,552°F), well in excess of the capacity of metal recuperators. Low pressure dropA short flow path through a ceramic matrix of small passages results in a consistently low pressure drop. Shell-and-tube exchangers attempt to improve effectiveness by increasing core density with smaller-diameter tubes, but at the sacrifice of a corresponding increase in pressure drop. Small sizeThe relative small size of the rotating ceramic disk used in a regenerator results in a very compact heat exchanger that can often be a fraction of the size of its shell-and-tube equivalent. Small size reduces installation cost and increases ease of retrofit. Reduced emissionsThe ceramic matrix is ideal for high-temperature gas applications and can be developed for use with catalysts to treat exhaust emissions. Low leakageThe leakage rate across seals can range from 2% to 15% of mass flow. For applications that do not tolerate cross contamination (mixing of the two streams), purge sections can be designed to capture leakage and direct it to an appropriate exhaust. |
