Coflore ATR

Pilot Scale Flow Reactor

The Coflore® Agitated Tube Reactor (ATR) is an actively-mixed tubular flow reactor that employs the same mixing principles as the smaller ACR reactor.  The Coflore ATR operates from 0.35 L to 10 L in reactor volume, and has been developed for the pilot-scale production of material. Configured of up to eight reactor tubes in series, the ATR flow reactor exhibits excellent plug-flow, with experimental data demonstrating well-over 100 theoretical stages.  Each of the eight tubes can be heated or cooled independently of each other and reagents can be added (or samples removed) at each end of each reaction tube. 

The Coflore ATR can handle a wide range of reagent mixtures; even those with heavy slurries without blocking, making it ideal for a wide range of processes including hydrogenation, which can be fully-automated for ease-of-use and safety.

For a 5-minute residence time, the Coflore ATR can continuously produce up to 120 L per hour, or 2,880 L continuously per day.

The Coflore ATR  is a flexible, versatile and and efficient plug-flow reactor. Its unique characteristics stem from the use of radial mechanical stirring rather than passive mixing. This approach decouples plug-flow and mixing from residence time, to give very low dispersion numbers, fast blending and high shear.
