Plate & Frame Heat Exchanger
Compact, serviceable, and efficient — the workhorse of process heat transfer.
Some plate & frame problems don't fit neatly into a sizing run. A unique fluid combination with unusual viscosity or fouling behavior, a tight footprint that rules out standard frame sizes, or a unit already installed and underperforming — these need a person, not just a calculation.
Our engineering team designs plate & frame exchangers directly for exactly these cases, working through the same thermal-hydraulic fundamentals behind our N-PHE software, but applying engineering judgment where a standard sizing algorithm would need manual override — non-standard chevron combinations, mixed-plate packs, or unusual port arrangements to fit an existing pipe layout.
We also handle troubleshooting on installed units: falling performance, excessive pressure drop, or premature fouling that a maintenance team can't diagnose on their own. Because we understand both the plate-side physics and the mechanical realities of frame assembly, we can trace a performance problem back to its actual cause — gasket degradation, flow maldistribution, or genuine undersizing — rather than guessing.
Typical engagements run from a single design review to full new-installation engineering, and we scope each one based on what's actually needed — a two-hour sanity check on someone else's design, or a complete specification built from your process data upward.
