          Product Description

          Heat Exchanger Is A Device In Which Heat Is Transferred From One Fluid To Another. The Apparatus Consists Of A Concentric Tube Heat Exchanger. Hot Water Flows through Inner Tube In One Direction Only And Cold Water Flows Through The Outer Tubes. Direction Of Cold Fluid Flow Can Be Changed From Parallel Or Counter To Hot Water So That Unit Can Be Operated As Parallel Or Counter Flow Heat Exchanger. Flow Rates Of Hot And Cold Water Are Measured Using Rota Meters. A Magnetic Drive Pump Is Used To Circulate The Hot Water From A Re-Cycled Type Water Tank, Which Is Fitted With Heaters And Digital Temperature Controller.

          Experimentation:
