Are you researching

functional films for Li-Ion batteries, OLEDs, OPV systems, fuel cells, catalysts, medical diagnostic coatings, thin film optical switches or other high tech functional films?

Then you know all about the pain of drying high-tech films in a lab.

Surface deformation, particle agglomeration, severe cracking and overall abysmal product performance, anyone? Don't get us even started...

Here at CNDT we worked incredibly hard to make all that history and build a batch-process drying system that delivers production-street-level performance at lab-size.

Well, here you are.

Positioning System

The positioning system has been integrated to allow a maximum level of comfort in the interaction process of coating and drying. Based on a button-click, the drying hood can be lifted during the coating process and repositioned to the exact distance between substrate and drying hood for the drying process.

Positioning System

By allowing easy access to your substrate even mid-drying-process our positioning system makes drying even the most complicated of coatings a convenient task.

Whether you need to quickly rearrange, probe or manipulate your coating, at the click of  a button you can lift the drying hood during and then lower it back to the exact same position it was at before.

Air Heater

The integrated air heater allows drying experiments at fluid temperatures up to 150°C.

Heat Exchanger

As physics dictate, the temperature of the compressed air leaving the side channel blower is always higher than at its intake.

At full compressor load it may rise to up to 70°C. 

None-the-less, thanks to powerful  heat exchangers, the CND-1000 can reliably dry at ambient temperatures.

Side Channel Blowers

Two side channel blowers provide the system’s desired mass flow rate at the required supply pressure.  

While the pressure side blower comes as a standard side channel blower, the suction side features an ATEX compliant variant, making the whole system practically explosion proof.

Massflow Control System

The mass flow controller integrated in suction and pressure side of the drying system automatically drive the power input to the side channel blowers based on drying conditions set by the user.

The Drying Hood

Our patented drying hood is the center piece of the system. It consists of the characteristic array of comb nozzles and fluid vents as well the complex infrastructure managing the internal mass flow distribution.

The latter assures that each nozzle receives exactly the same kind of mass flow and that each of the integrated exit slots removes exactly the same amount of drying fluid.

SPS Steering Unit

The complex interplay between all components of the CND-1000 is orchestrated by a SPS steering unit.

Based on the drying conditions specified by the user, a correlation based algorithm will adjust all internal parameters to achieve the desired boundary conditions.

Take The Guesswork Out Of Your Development Process

By far the most time and cost intensive steps in getting the latest functional coatings market ready all lie between process engineering stage and production pilot.  

CN Drying Technology gives process engineers the means for consistent homogeneous drying at reproducible drying conditions. Not only does that dramatically reduce the amount of necessary iterations between material development and process engineering, it also eliminates the need for running production pilots all together. 

However, the revamped development process does more than just saving you massive amounts of time, money, material and nerves. It actually makes the whole development process calculable and projectable, effectively putting you back where you belong: in control.  

Additionally: It’s also nice if stuff just works for once.

Comparing an Advanced Round Nozzle Dryer with the CND-1000

Advanced Round Nozzle (ARN) impingement dryers deserve the label advanced because they already feature CNDT patented air-vents that remove spent fluid before it can create messy interactions effects with the jets of the surrounding nozzles. 
They represent an earlier stage in the development of the CND-1000.

Spent fluid removal alone will allow standard lab dryers to bring down percentage deviation from perfect homogeneity by factor five, or, in other words, down to a mere 25%.

Yet, combining local fluid removal with our patented comb nozzle impingement jets is where the real magic happens. It allows us to reduce local fluctuations in HTC to near perfect rates of 5%, all the while offering absolute control over all relevant drying parameters.

Staff Engineer, Process Catalysis and Solid Processing @ BASF

"The CND-1000 thin-film test device comes with a straightforward, user-friendly design, supporting us to significantly reduce the time we need to run experiments. All-the-while individual experiments yield highly reliable data.

With this tool in hand, we can easily recreate production-level drying conditions in our laboratory. Iterative steps for scaling drying processes on larger pilot systems are now practically obsolete."
