Air Temperature Control Unit-18
The ATCU-18 accommodates enclosure:
Area: Up to 17 m²
Volume: Up to 34 m³
Ultra-Precision Temperature Control
For cleanrooms and large precision equipment.
• We guarantee that a Præcis air temperature
control system will maintain the temperature
at the Critical Point to 0.008 °C p-v (± 0.004).
• . 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.
ATCU-18 maximum enclosure size.
