Importance of preventive maintenance and checking and replacement of gaskets to ensure full efficiency of plate heat exchangers for temperature control in the production process industry.
Why and how do heat exchangers get dirty, scaling of thermal transfer surfaces or fouling due to dirty fluids with solid suspended particles flowing inside the exchanger, and the possible interventions aimed at maintaining the thermal transfer efficiency.
Fouling Factor is a crucial element to evaluate for the sizing of plate heat exchangers upon the conditions of a certain thermal application, in order to ensure the best flow rate of the fluids inside the exchangers and maximizing the thermal transfer efficiency.
Crossing of temperatures in plate heat exchangers and shell and tube exchangers with fouling problems and thermal energy recovery.
ATEX certifications, anti-corrosion treatments and the selection of construction materials that cope with challenging and harsh working conditions of oil & gas indutrial plants can turn a simple plate heat exchanger into something very special.
Micro channel brazed plate heat exchangers employed in chillers allow to reduce the amount of refrigerants flowing within the exchanger, contributing to the reduction of emissions and greenhouse gases in industrial refrigeration.
Increase in pressure drop between inlet and outlet of the fluid and the decrease of temperature levels are the key parameter indicators to determine the right moment for preventive maintenance on heat exchangers.
Maintenance intervention with cleaning and complete regeneration of plate heat exchangers for a plastic material grains manufacturer, with penetrating liquids test on plates.
Chemical fouling, biological fouling, deposition fouling and corrosion fouling: how to evaluate the fouling factor on heat exchangers preventing fouling on thermal transfer surfaces.
The selection of the size of hydraulic passages in plate heat exchangers is based on the application, from brazed plate exchangers to free-flow exchangers operating with dirty fluids.
