Plate Heat Exchanger Vs Spiral Heat Exchanger

Plate Heat Exchanger

  • Additional equipment/components are required for the secondary circulation loops like a Secondary Circulation pump along with a control panel and extra piping and valves required.

  • Extra Power Consumption for the secondary circulation pump.

  • Heat loss via PHE which is generally not insulated and secondary circulation loop pipings, valves and fittings.

Spiral Heat Exchanger

  • No secondary circulation loop is required.

  • Only one circulation pump power consumption.

  • No external HE and secondary circulation loop.

  • PHE requires maintenance like the replacement of gaskets and has a limited life of approx. 10 years.

  • Extra investment on the secondary pump, control panel & secondary loop piping, valves and fitting.

  • Larger footprints due to external PHE & Secondary Loop.

  • SHE requires zero maintenance and her life is more than 25 years.

  • Approx. 20-40% less capital cost

  • Fewer footprints due to no external HE & Secondary loop requirement and there are only primary pipings outside.
