The Numerix Heat Exchanger Configurator is plate heat exchanger sizing software. Enter duty, fluids, and operating conditions; it returns a validated PHE size, plate count, performance curves, and a branded PDF quote — in under 2 minutes. Built on validated NTU-ε / Martin / Kumar correlations.
Plate heat exchanger OEMs, distributors, sales engineers, and end users who size PHEs repeatedly. Replaces spreadsheets, vendor calculators, and manual sizing time. Also used for CDU sizing in liquid-cooled data centres.
Out of the box: 28 fluids covering process water, glycols, oils, refrigerants, and common process streams. Custom fluids can be added via property tables. Single-phase, sensible heat duties on plate-and-frame geometry.
Yes — five published benchmarks against Martin (1996) and Kumar (1984) correlations, plus operating-data validation from PHE OEM partners.
