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.
