Heat Exchanger Design - Design Calculators

Heat Exchanger Design Calculator

This calculator assists in the design and analysis of heat exchangers using two fundamental methods:

Log Mean Temperature Difference (LMTD) Method: Suitable for known inlet and outlet temperatures of both fluids and helps determine the required heat transfer area.
Effectiveness-Number of Transfer Units (Effectiveness-NTU) Method: Ideal when only inlet temperatures are known and the heat exchanger performance (effectiveness) or size (NTU) needs to be evaluated.

Choose the appropriate method and unit system, input your fluid and heat exchanger parameters, and let the tool calculate the key design values.
