HRS Heat Exchangers Software
vertical specialistSelection and sizing software for corrugated tube and plate heat exchangers.
Datasheet-style outputs from configured exchanger studies reduce manual re-entry during iterations.
HRS Heat Exchangers Software is oriented around performing thermal design calculations and then turning those results into documentation-ready outputs for exchanger selection. The workflow is structured around configuring exchanger type, flow arrangement, and geometry-related parameters before calculations run. It supports iteration by recalculating thermal performance under modified inputs to narrow to feasible designs.
A tradeoff appears in how tightly the workflow aligns with common exchanger design conventions rather than broad model extensibility for custom correlations. The tool fits situations where teams need repeatable exchanger sizing outputs for engineering reviews rather than building a bespoke property or correlation engine.
- +Output sets include calculation results suitable for exchanger selection reviews
- +Iterative runs support quickly updating duty and operating constraints
- +Configuration workflow keeps geometry and operating inputs tied to results
- +Datasheet-oriented exports reduce manual formatting during handoff
