MAGCalc: Expansion Vessel

MAGCalc helps heating and HVAC technicians size membrane expansion vessels and prepare precharge and filling pressures. WATER SIZING Record system volume, temperature, static height and safety valve pressure. Estimate water expansion and view the next standard vessel size. INSTALLATIONS AND SCENARIOS Save named installation projects with location notes. Create and duplicate independent scenarios, select a reference and compare results. Keep input sources and assumptions with each scenario. Share a calculation record containing inputs, results and differences. German and English. Calculations and local projects work offline. MAGCalc Pro unlocks manual expansion calculations for glycol, solar fluids and special media through a one-time in-app purchase. Water sizing and project management are available without that additional purchase. Professional calculation aid: manufacturer data, applicable rules, system design and actual measurements take precedence. Check results against the real installation.
