Why choose Dinex double swirl inline mixer?
1. Modularity and Scalability
The mixer has been applied for a range of different applications, including on-road, stationary, and off-road, across a variety of diameters. For all applications the mixer is designed, tested and simulated using methodologies developed in-house.
The versatility of the mixer is created by tailoring each of the three design elements. Deposit performance is governed by the evaporation device, instigating swirl around the spray plume, pressure drop can be modulated by the transition from evaporation device to distribution module and finally, distribution can be adjusted in the distribution module. The optimum is found in balancing these three elements, illustrated here in an on-road application.

2. NH3 Distribution
Ensuring NH3 distribution is crucial for future-proofing the technology. Distribution is quantified by a uniformity index, where a value
of 1 indicates ideal distribution. The left side illustrates the performance of a 9,5” dia. mixer.
High uniformity and good consistency between simulated & tested results.

3. Deposit Resilience
Deposit testing can be conducted through various methods. On the left, we observe exemplary deposit screening results, short stationary tests, performed to see what amount of dosing can be achieved without accumulating deposits. On the right we see comparative results, illustrating how results can be improved through CFD simulation. In this case the results are from a long duration stationary testing. Deposit testing can also be performed in Dinex under transient or pseudo-transient conditions.
Deposit screening results presented in the form of the energy availability ratio – a measure of how efficiently the mixer utilizes the energy available in the gas stream – lower is better
