For highest product quality, we at VTA optimize temperature, process pressure, feed rate, and wiper speed.
Temperature and pressure mainly determine the evaporation rate, the feed amount influences the residence time and therefore the thermal stress on the product.
Through precise control and suitable sensors, we ensure reproducible conditions – from laboratory scale to pilot plants and up to industrial production.

As a manufacturer of complete solutions, we use both processes depending on the product requirements.
Both processes operate under vacuum with a thin product film on the evaporator wall and are designed for high product quality and efficiency.
In thin film or wiped film distillation, the light-boiling component condenses in an external condenser; in short path distillation, it condenses on an internal condenser.
Due to the low pressure drop and the resulting very low distillation pressures, short path distillation is particularly gentle and ideal for temperature sensitive products.

The achievable purity depends on the product composition, the corresponding boiling points and the required product yield.
As part of feasibility studies and pilot tests, we define the realistic target values together with you.
Depending on the application, very high purities can be achieved; in other cases, an economically reasonable purity (e.g. ~80%) is more appropriate.
Multistage concepts, re runs, or combinations (falling film/thin film/short path) significantly increase the separation performance.

As a plant manufacturer, we provide comprehensive consulting: from product viscosity, temperature sensitivity, and target purity to throughput and scale up, all the way to installation and layout concepts.
In our test center we determine the process window and use this to define the plant type, number of stages, wiper system, evaporator size, and vacuum concept.
The result is a customized VTA plant design, validated on our pilot units – including a clear economic evaluation.

Key factors are: temperature and pressure within the optimal range, an adjusted feed rate, wiper speed (film quality), condenser / cold trap design, as well as possible multi stage configurations.
VTA special wipers and process specific surfaces reduce fouling and increase separation efficiency.
Through visualization and control of the systems with suitable control strategies, we make improvements reproducible.

Through visualization and control of the systems with suitable control strategies, calibrated sensors, and validated scale up methods.
Pilot trial data from the VTA technical center are transferred to the industrial plant.
In this way, you achieve scalable processes from laboratory scale to production.

VTA uses short residence times, optimized film formation (wiper system), low pressures, and adjusted temperature profiles.
Short path distillation (molecular distillation) with optimized vapor flow and low operating pressures reduces the thermal stress for the product.
An optimized film formation together with suitable material and surface treatment can reduce fouling; special wiper systems make it possible to distill higher‑viscosity products in a thin film evaporator.

Possible causes include leakages, contamination/deposits, or incorrect calibration of the measuring devices; the vacuum system must also be checked in detail.
Our VTA After Sales team supports you with diagnosis and troubleshooting – worldwide.
Final pressure measurements of the vacuum system and performing leak tests can be the first diagnostic steps in addition to checking the components.
Maintenance intervals and the instructions in the corresponding operating and maintenance manuals must be followed.

Yes. VTA offers practical trainings worldwide – for plant operators as well as for engineering departments and decision makers.
Different topics can be covered after prior agreement: e.g. plant design, operation & optimization, quality & reproducibility, troubleshooting, or an economic evaluation of toll distillation compared to an investment in your own plant.
On request, we also offer in house trainings at your plant.
You can receive current dates and offers directly from VTA.
