I would like to ask everyone: How long can a 350 air separation unit be shut down temporarily, under the condition that liquid oxygen is not discharged? Must the 3 delivery valves be closed during parking? Which other valves need to be closed?
Additional question: How long does it generally take for a small air separation unit to be shut down before liquid oxygen needs to be drained? What issues need to be considered when not using liquid oxygen? Also, how long can the heating element of an electric heater generally last?
