Our product lines

Two architectures, one manufacturing team

Every unit is the output of an NSGA-II multi-objective optimisation on your exact duty, not an off-the-shelf product. Delivered with a full thermo-hydraulic report.

Patented TRL 5 · 5 prototypes tested Flagship: MST-Q150M50

Modular Shell & Tube Platform

Section-wise parameterisation: (N_t, D_o, P_t, t_w, material) tuned independently per section. Welded partitions eliminate Tinker bypass. Rectangular envelope removes cylindrical dead volume. Result vs TEMA: −50% ΔP, −37% mass, +10 pts effectiveness at iso-duty.

  • Central hot plenum S0 → symmetric S1–S4 bundles each side
  • Ultra-thin tubes 0.08–0.15 mm wall · laser-welded or brazed
  • Inconel/310S hot sections · SS 304/carbon cold sections
  • Zero shell-side bypass, welded partitions, not baffles
  • Envelope: 499 × 178 × 689 mm · β ≈ 245 m²/m³
  • Customisable: per-duty NSGA-II re-run, proposal in 10 working days

3D-Printed Additive Line

Patented winglet-offset fin architecture, topology-optimised, flow-adaptive, impossible to stamp or braze. Printed monolithic in 310S, 309 or Inconel. −20 to −35% ΔP vs classical offset strip fins at iso-effectiveness. Zero brazed joints, zero leak paths.
