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.

A Plate And Frame requires only 20% to 50% the space of shell and tube units including service footprint. They are much lighter in weight, and they cost less.


Plate & FrameShell & Tube
“U” or “K” values several times greater than shell and tubeLow efficiency
Can be designed for less than a 1°C(2°F) temperature approachTypically designed for greater than a 3°C to 5°C(5°F to 10°F) temperature approach
Easy disassembly within its own footprintRequires twice its length to pull tube bundle; complex disassembly—tube bundle must be pulled
Low fouling due to corrugations and inherent turbulence3 to 10 times greater fouling due to circular cross-section and laminar flow
Practically no heat loss—no insulation requiredGreat amount of heat loss—insulation required
