Why Specify Plate And Frame Instead Of Shell And Tube?
SUPERCHANGER® Plate And Frame Heat Exchangers transfer heat more efficiently than shell and tube units in most applications, due in large measure to the turbulent flow created by the corrugated patterns of their plates. They use only 20% to 50% of space required by shell and tube units including service footprint and are much lighter in weight. And, they cost less. As long as the operating temperatures and pressures do not exceed 180°C (356°F) or 27.5 bar (400 psi), a plate heat exchanger is worth a look.
|Plate & Frame||Shell & Tube|
|“U” or “K” values several times greater than shell and tube||Low efficiency|
|Can be designed for less than a 1°C(2°F) temperature approach||Typically designed for greater than a 3°C to 5°C(5°F to 10°F) temperature approach|
|Easy disassembly within its own footprint||Requires twice its length to pull tube bundle; complex disassembly—tube bundle must be pulled|
|Low fouling due to corrugations and inherent turbulence||3 to 10 times greater fouling due to circular cross-section and laminar flow|
|Practically no heat loss—no insulation required||Great amount of heat loss—insulation required|
