Stop #1(1st) cooler Close its air flow adjuster.

Stop KOACHs 2 minute after the coolers operation.

  • Working mode

Operate both coolers at "23.8C" with fully opening the air adjusters. Operate KOACHs. Open two doors (door btw outside and sound proof room and door btw pre-room and clean room) of the PSL room with 10cm space.

The attached graph shows each temp during working mode. "Booth_PSL temp(set inside the clean area)" keeps almost same temp with that before action with short time disturbance.

(The air adjuster is situated at the bottom of a duct of the precision cooler. You can slide a metal plate by hand.)
