Thermal evaporator VK series

short pathprocessfor liquids

SHORT PATH EVAPORATORS Lowest distillation pressure for high boiling and thermal sensitive products Short path - or molecular - distillation allows the evaporation of heat sensitive products at operating pressures down to 0,001 mbar at short residence times. On a cylindrical heating jacket the product is distributed and turbulized by a wiping system. The evaporated fraction is condensed on a condenser installed in the center of the evaporator. This arrangement minimizes the path from evaporation to condensing surface and achieves the lowest possible pressure drop. The high vacuum and the short residence time avoids thermal stress and decomposition of the processed products.
