Dynamically Mixed Flow Reactor | DART-DM

We offer a comprehensive range of value engineered, dynamically mixed continuous flow reactors and peripheral equipment.
Salient features include:
Modular design capable of operating as a single stage system, or as a multistage cascade, or for parallel processing
Our reactors are fully scalable, with nominal working volumes from 3ml to industrial scales of 50L and beyond.
Variable Volume capabilities within a fixed tube geometry
Materials of construction - Glass, Stainless Steels, Exotic Alloys such as Hastelloy C22 and chemically resistant engineering plastics, such as Peek, PTFE and PFA
Single or Multi-Zone heating/cooling jacket options are available
Bespoke  designs to match unit operation and customer requirements
Control System ranging from basic on/off agitation with variable speed, to a more sophisticated PLC based systems with optional ATEX certification
3 fundimental design forms cover a wide range of operating conditions
DART reactors are dynamically mixed and can be used to tackle many challenging flow processes, involving gas, liquids and highly concentrated suspended solids.  Light sources can also be used for photcochemisrty applications.
Reactors designed specifically for biochemistry and photochemistry are also available.  An Electrochemical reactor is in development and is due for release in 2021. 

DART compared to Micro Reactors:

Many people may be familiar with the benefits and limitations of micro tubes and channels, but some maybe less so with the benefits of dynamically mixed reactors such as DART.

Due to their relatively small flow geometry, conventional micro reactors are extremely capable. The advantages of the DART over micro reactors are few in number but are nevertheless totally compelling:

  • SOLIDS HANDLING - The annular channel in a DART reactor provides a higher working volume than that in a micro reactor, but without sacrificing the amazing performance of micro reactors. Consequently where solids concentrations reach the point where micro channels block DART reactors continue to operate.
  • HEAT TRANSFER - The shear created by the spinning agitator results in much better U values than are possible with micro reactors.
  • MASS TRANSFER - The shear created by the spinning effect of the agitator produces vastly better mass transfer than is possible in a micro reactor under the same flow conditions.

DART Mixing Methodologies

DART-CSTR DART-DM with CSTR mixing

CSTR Flow Reactor Cascade

Based on batch reactor technology, the CSTR is a relatively straight-forward and easy to understand flow reactor. The simplicity of design makes the CSTR a popular choice, but it is important to understand the nuances of the system design to determine if it will deliver reliable and repeatable performance.

DART-TVR DART-DM with Taylor Vortex mixing

Taylor Vortex Flow Reactor

Taylor Vortex Reactors can generate homogenous micro-mixing zones. By generating strongly mixed zones, it is possible to achieve faster chemical reaction speeds and shorter cycle times. The tightly mixed zones also assist the production of high purity products with uniform-sized particles.

DART-DM DART-DM with patented 2D mixing technology

2D Mixed Flow Reactors

2D Mixed reactors are designed to mix in the radial plane only.  They are mostly operated at or near horizontal and offer unparalleled performance when handling multiphase processes.
