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.

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 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.
