Performance monitoring and predictive maintenance software for shell-and-tube heat exchanger networks

SmartPM^TM simulates complex networks of shell-and-tube heat exchangers to help engineers and plant operators manage fouling. Used in exchanger networks such as refinery preheat trains, SmartPM predicts future performance, including the effects of fouling build-up, and can help achieve energy savings and maintain throughput by scheduling exchanger cleanings.

Combining HTRI’s single- and two-phase detailed exchanger analysis methods with advanced techniques for exchanger network simulation makes SmartPM the most robust, validated thermo-hydraulic simulator of its type. Its use of dynamic fouling models allows engineers to evaluate the best options for mitigating fouling.
