Hot gas enters S0 central plenum and distributes symmetrically left and right through sections S1–S4, each with its own thermal and material specification.
HEAX Recuperator V6.0: the physical product behind the architecture
Flow path analysis (top) and CFD thermal simulation 178–680 °C (bottom)
Every prototype is backed by our in-house CFD pipeline and NSGA-II optimization code, then physically tested on our dedicated bench.
Pay for Inconel only where it's needed. Each module section is independently specified for its local thermal and mechanical environment.
Same duty (158 kW, air-to-air). Half the backpressure. 37% less mass.

Laser welded prototype (50L) at the Versailles-Satory test facility
The compact footprint and extreme temperature range make this design uniquely suited where conventional Shell & Tube simply won't fit.
