ATCU-18 All
 

Ultra-Precision Temperature Control For Drum Roll Lathes and Custom Build Cleanrooms.

 

• We guarantee that a Præcis air temperature control system will maintain the temperature control at the Critical Point to ± 0.003 °C.

• Præcis systems provide long-term temperature stability and do not require operator intervention. The ATCU screen displays the temperature in real time, and if the temperature should go out of range, the ATCU will sound an alarm.

• If your Præcis Environment system should need adjustment, Præcis provides remote tuning from its headquarters.
