HEAT EXCHANGER SERVICE UNIT WITH WATER TO WATER TURBULENT FLOW HEAT EXCHANGER
Heat Exchanger Service Unit is bench mounted, fully instrumented and operates from conventional single phase electrical supply and mains water.
The unit provides services for any of the optional heat exchangers.
The hot water system is equipped with a safety temperature limiting device.
The instrumentation consists of up to 12 type T thermocouples, displayed on a digital panel meter, and two flow-meters for hot and cold fluids.
A Computerized Data Acquisition Upgrade provided with the unit and a Water to Water Turbulent Flow Heat Exchanger
Determine the heat transfer rate, logarithmic mean temperature difference, and overall heat transfer coefficient and 4 point hot and cold stream temperature profiles.
determination of surface heat transfer coefficient inside and outside the tube, and of the effect of fluid velocity.
Comparison of performance in concurrent and in counter-current flow
