exhaustedtemperaturereaction front

CO₂ + H₂O → H₂CO₃① CO₂ dissolves in the pellet's surface water film

H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O + heat② fast neutralisation by NaOH (catalyst)

Na₂CO₃ + Ca(OH)₂ → CaCO₃ + 2NaOH③ slow step: lime locks CO₂ as chalk, regenerating NaOH

The exhale lung feeds the upper canister; gas crosses it outwards, runs along the main cover and crosses the lower canister back into the inhale lung, where the cells sit. The front eats the upper canister first: cycling moves the half-used bottom canister to the top. Cycle up to 3 h 15 on the stack, past that replace both; 4 h limit. The rMS (▼ on the profile) finds the front from the bed temperature. Manual: > 160 min at 40 m, 4 °C, 40 L/min; > 75 min at 100 m.
