H102H Coiled Concentric Tube Heat Exchanger
An example of an industrial coiled concentric tube heat exchanger with turbulence enhancing tubes. The heat exchanger is fully instrumented using the Heat Exchanger Service Unit H102 with thermocouples on the inlet and outlet of both the hot and cold streams.
The heat exchanger can be arranged so that either hot or cold streams are in the inner tube. With either configuration both co-current and counter-current flow can be established.
The heat exchanger is deliberately not insulated so that heat losses in all of the configurations can be investigated.
