Interactive diagrams and calculators for thermal engineering — precise, print-ready and running entirely in your browser.
From moist air to real gases — open a tool and start calculating. Nothing leaves your machine.
Enthalpy–humidity chart for moist air. Model air conditioning, drying and humidification processes state by state.
Pressure–enthalpy and temperature–entropy charts. Lay out vapour-compression cycles and read every state at a glance.
Pressure–volume diagrams for piston machines and gas processes. Otto, Diesel and Stirling cycles with work and efficiency.
Compare refrigerants side by side: thermodynamic properties, GWP, safety class and cycle performance in one view.
Size pipes and select standard DN from flow, velocity and pressure-drop limits — with material data built in.
Assess water quality for heat-exchanger duty: hardness, conductivity, chlorides and fouling limits at a glance.
Generalized compressibility (Z) charts. Correct ideal-gas calculations for real-gas behaviour at any reduced state.

Every model runs locally in your browser. No installs, no accounts, no server round-trips — open a tool and get to work.
Diagrams are computed from established property formulations and standard correlations — not hand-drawn approximations.
Clean, readable output that drops straight into reports, design notes and presentations. Print-ready by default.
