About this app

AIRExpander Pro is the paid version of AIRExpander — dry standard air expansion for turbo expanders, with extended tools for precise engineering work.

PRO FEATURES (rolling out)
• Precise numeric input (not only sliders)
• Full state properties: enthalpy, entropy, specific volume at inlet and exhaust
• Same robust dry-air thermodynamics as free AIRExpander
• Calculate power, mass flow or isentropic efficiency
• Copy / share results (planned)
• Light and dark themes, German and English UI

HOW IT WORKS
• Set inlet pressure, inlet temperature and exhaust pressure
• Choose what to solve for (power, mass flow or efficiency)
• Review exhaust temperature, flows and enthalpy drops

UNITS
• Pressure: bar absolute · Temperature: °C · Mass flow: kg/s · Power: kW · Efficiency: %

Also available free: “AIRExpander” (slider-only exploration).

IMPORTANT
Provided in good faith without warranty of correctness or completeness. Always verify critical calculations.
