What dew point should activate the required alarms when the dew point at system pressure exceeds?

The dew point is an important parameter in medical gas systems because it indicates the temperature at which water vapor in the gas will begin to condense into liquid form. When the dew point at system pressure exceeds a certain threshold, it can lead to moisture accumulation within the gas lines, which may cause corrosion, microbial growth, or contamination of the medical gas. These issues can compromise the quality and safety of the gas being delivered to patients.

Setting alarm thresholds is a critical part of maintaining the integrity of a medical gas system. A dew point of 35°F is recognized as the appropriate point for alarm activation. This threshold allows for a buffer against potential issues caused by condensation of moisture in the lines, thus ensuring the gas remains dry and within the required specifications for safe medical use. Monitoring this dew point and having an alarm set at this level helps technicians respond promptly to potential issues before they become significant problems for patient care and the equipment itself.
