⚙️ TEMA Class R/C/B Shell & Tube Exchangers, Log Mean Temp Difference LMTD & Area

TEMA Shell & Tube Heat Exchanger Calculator

Size industrial shell and tube heat exchangers under Tubular Exchanger Manufacturers Association (TEMA) standards: calculate Log Mean Temperature Difference (LMTD with F-correction factors), required heat transfer surface area (Square Feet = Heat Duty BTU / [Overall U-Factor x LMTD]), tube pass counts (1, 2, or 4-pass), and mechanical margins.

1. Project & Operating Inputs

Thermal Heat Duty (MBTU / Hr e.g. 6,500 MBTU/Hr Duty)

Overall Heat Transfer Coefficient U (BTU / hr-sqft-°F e.g. 185 U-Factor)
