Engineering capability
Performance is designed in—before metal is cut.
Our work begins with the real process conditions. Thermal sizing, mechanical integrity, material compatibility and maintainability are treated as one engineering problem.
Thermal design
HTRI and Aspen-assisted modelling for duty, pressure drop, phase change and close temperature approaches.
Mechanical design
Pressure, temperature, nozzle loads and structural requirements developed around the operating envelope.
Quality control
Pressure testing, leak detection, dimensional checks and traceable documentation for reliable service.
Lifecycle support
Selection, replacement, plate packs, accessories and practical maintenance guidance from one team.

Frequently asked questions
Heat exchanger selection, explained.
Which heat exchanger type is best for my application?
The right type depends on the media, temperatures, pressure, allowable pressure drop, fouling tendency, hygiene requirements and maintenance plan. Share your duty data and our engineers can compare the practical options.
Can HEXNOVAS replace an existing exchanger?
Yes. HEXNOVAS supports replacement projects for discontinued or underperforming units, including thermal re-rating, dimensional review, connection matching and alternative material selection.
What information is needed for heat exchanger sizing?
For each side, provide fluid name, inlet and target outlet temperature, flow rate, operating and design pressure, allowable pressure drop and any known fouling or material constraints.
Which standards can HEXNOVAS support?
Projects can be engineered in line with relevant ASME, PED, EN and GB practices, depending on equipment type, destination and project requirements.
