?Some like it hot - but not expensive?

#Heatexchangers are a central component of many process plants and can be found in almost all industrial sectors. They play an important role in the stabilization of process temperatures and the recovery of thermal energy, which contributes significantly to sustainable and resource-saving production. Regular inspection of heat exchangers is essential to ensure their proper functioning. Problems such as #dirt, #corrosion or #fouling can severely affect efficiency. To monitor the performance of heat exchangers, a #conditionmonitoring solution is a good option. This helps to keep an eye on efficiency and to schedule maintenance work in good time.The efficiency of a heat exchanger can be monitored by using suitable sensors that provide relevant data.

• ?? Measuring the #temperature difference between the inlet and outlet is crucial. A decreasing temperature difference may indicate reduced efficiency.
• ????Measuring #pressure drop is also important. An increased pressure drop across the heat exchanger may indicate blockages caused by dirt.
• ?? ?Monitoring #flow rates can be enlightening. A drop in flow velocity below a certain level may indicate a blockage.
• ?? #Vibration measurement technology can be used for heat exchangers with moving parts. Changes in frequencies, for example, can indicate deposits.

It is not absolutely necessary to query all parameters in parallel. Depending on the application, the temperature or differential pressure is absolutely sufficient. Since heat exchangers are central components in a process plant and failure results in long downtimes, monitoring is very useful. Without question, the investment for the installation is more than compensated by an unplanned shutdown. #Turck offers you a wide range of sensors (e.g. the new #PS+ or #FS+ series) and, depending on the systems in which the evaluation and monitoring is to be carried out, you can choose between a PLC/DCS version with the #TBEN I/O modules or, for convenient data ejection via #MQTT or #OPCUA, with the #IM18CCM60 condition monitoring platform. With the monitoring of heat exchangers, you increase the availability of your systems and reduce the costs caused by unplanned downtimes.
