Plate heat exchanger calculator for preliminary sizing
Size a plate heat exchanger from duty and process conditions, or check the performance of a fixed plate count and area. Geometry-based U, LMTD/F correction, pressure drop, and validation scoring stay visible the whole way through.
What XHeat calculates
XHeat walks through a plate heat exchanger preliminary sizing the way an engineer would check it by hand, with every assumption visible and editable.
Duty and LMTD
Solve duty, outlet temperatures, or flow from process conditions, with LMTD and an F correction for multi-pass arrangements.
Geometry-based U
Calculate h_hot, h_cold, and overall U from plate gap, width, length, chevron angle, and correlation constants, iterating plate count until consistent.
Pressure drop
Channel and port pressure drop breakdown by side, with velocity and Reynolds number checks against typical PHE ranges.
Validation and sensitivity
Confidence scoring against energy balance, correlation range, and hydraulic limits, plus sensitivity analysis and case comparison across plate presets.
