The sensitivity of carbon molecular sieves to temperature
The high temperature sensitivity of carbon molecular sieve is an inherent characteristic of PSA nitrogen generation. Elevated temperature does not damage the material but significantly reduces oxygen–nitrogen separation efficiency, affecting nitrogen recovery and energy consumption.
Why is the air temperature still high after an air dryer?
Answer：
Refrigerated dryers are designed mainly for moisture removal, not deep cooling. Under high ambient temperature, outlet air may still reach 35–40 °C.
Does long-term high temperature operation shorten CMS service life?
Answer：
It may accelerate performance degradation, but this is due to operating conditions, not product defects.
How to distinguish temperature issues from CMS quality issues?
Answer：
Recommended checks:
Measure inlet air temperature
Check if it is continuously above 35–40 °C
Compare performance during cooler periods
Observe performance recovery after temperature reduction
Is performance reduction under high temperature covered by warranty?
Answer：
If inlet air temperature exceeds the recommended range, performance reduction is generally considered an operating condition issue, not a material quality issue.
