AIRExpander Pro Turbo Expander

AIRExpander Pro calculates the expansion of dry standard air in turbo expanders – with precise numeric entry, full state properties at inlet and exhaust, and copy and share functions for your results. For engineering estimates, teaching and precise “what if” checks on the go. WHO IT’S FOR • Engineers in expander, compressed-air and plant engineering • Students and lecturers who want to work with exact numbers HOW IT WORKS • Set inlet pressure, inlet temperature and exhaust pressure • Choose what to solve for: power, mass flow or isentropic efficiency • Review exhaust temperature, volumetric flows and enthalpy drops PRO FEATURES • Precise numeric input (not only sliders) • Full state properties: enthalpy, entropy and specific volume at inlet and exhaust • Same dry-air thermodynamics as the free AIRExpander app • Solve for power, mass flow or isentropic efficiency • Copy and share results • Light and dark themes, English and German interface UNITS • Pressure: bar absolute • Temperature: °C • Mass flow: kg/s • Power: kW • Efficiency: % PURCHASE Paid app: buy once, no ads, no in-app purchases. To try it out first, the free version “AIRExpander” (slider-only) by MyEngineeringTools is available. ACCURACY Developed by a project engineer with more than 15 years of experience in turbomachinery and thermodynamic cycles. Provided in good faith but without warranty of correctness or completeness. Always verify critical calculations with your own methods and professional judgment. Get AIRExpander Pro for your next expander layout. Feedback is welcome at [email protected].
