Air Temperature Control Unit (ATCU) Overview 

Precision thermal control of enclosures. For those with enclosures already in place, a Præcis Air Temperature Control Unit (ATCU) can be attached to the enclosure as a retrofit.

Præcis has four ATCU models to accommodate enclosures from tabletop applications to entire rooms. Multiple ATCU's can be used to control the temperature in enclosures with a footprint larger than 17 m².

Basic features:

• We guarantee that a Præcis air temperature control system will maintain the
   temperature at the Critical Point from 0.01 p-v (± 0.005) °C. Select the amount of
   control that you need for your application.

• 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.

Retrofitting to Existing Enclosures.

A Præcis Environment ATCU can be attached to any enclosure. See our gallery for examples.
