Molecular sieve protection operation during parking
Reply #22010-03-31
Protect with nitrogen; a pressure slightly higher than atmospheric pressure is sufficient

It’s generally not necessary; as long as you stop at the right time – usually at the end of the cool-down phase or during the transition period – you’ll be able to meet the requirements when starting the vehicle again

For short-term parking, pay attention to the opinions of those on the 3rd floor, and make sure to maintain pressure to keep the instrument air supply stable. For long-term parking, the instrument air must be switched to a backup system; otherwise, once the instrument air is lost, the valves will revert to their original open/closed behavior, and the molecular sieve will absorb moisture, which will affect the temperature after the system is restarted – often regeneration is required.

It is best not to leave the molecular sieve in the heating phase; if a short-term shutdown is necessary, pressure can be maintained in the molecular sieve.
