ASC-500 50 kW Solvent Recovery Plant


The ASC-Series, one of the most modern distillation plants worldwide, is constructed with a com- pact design, is powerful and very easy to use.


solvent. At the same time a high distillation rate is reached with a small vessel volume. Only an electrical connection is necessary for the integrated steam heating system.


A high-speed vacuum pump transfers the dirty solvent to the evap- orator and guarantees a continuous 24 hour operation. During au- tomatic distillation the quantity of solvents which is evaporated is automatically refilled by small portions again. This automatic pro- cess is adjusted by the timer. Timer 1 "Continuous Distillation": If the set time has passed or the tank of dirty solvent is empty, the plant switches automatically to Timer 2. Timer 2: Final distillation mode "Sump Distillation". The continuous filling is stopped and the remaining solvent mixture in the vessel is evaporated to a thick concentrate. After the time has passed the plant switches off and is ready for the manual or fully automatic emptying.


The distilled and cleaned solvent flows continuously from the distilling plant into a build-lateral tank. A further characteristic of the ASC evaporators is a slow-running agitator with automatic self adjusting scraper blades made out of PTFE. These blades optimally clean the conical evaporator vessel and need no re-adjustment. The total distillation process is controlled by a SIEMENS micropro- cessor.


The ASC-500 is a most comfortable vacuum distillation unit out of the professional series ASC. It includes a modern integrated steam heating system.


A characteristic is the conical distillation vessel made of stainless steel, where the lateral surface is heated with steam. The steam in the double jacket transfers the energy extremely fast into the

The emptying of the high-viscosity residue is done by natural grav- ity over a drainage valve at the bottom of the conical round vessel. The plant can be re-filled again automatically with dirty solvent. A new continuous recycling process begins.
