The ASC-100 is a cost-effective alternative to the steam-driven solvent recovery systems. The ASC-100 is the smallest solvent recovery system from the professional ASC series.
The solvent recovery system as a modern integrated thermal oil heating system. A special feature of the solvent recovery system is the conical stainless steel distillation vessel, in which the shell surface of the solvent recovery system is heated with thermal oil. The hot oil in the double jacket of the solvent recovery system indirectly heats the solvent and then evaporates it. At the same time, a very good distillation performance is achieved with a small boiler volume.
Only one electrical connection for the solvent recovery system is required for the integrated thermal oil heating. A high performance liquid ring vacuum pump conveys the dirt into the solvent recovery system evaporator and guarantees continuous 24 hour operation. During automatic distillation, the evaporated amount of solvent is automatically replenished into the solvent recovery system by the addition of dirt. This automatic mode can be set by timer.
If the dirt tank of the customer contains no more solvent, the solvent recovery system receives a signal and automatically switches to "sump distillation". The continuous filling is stopped for the solvent recovery system and the amount of solvent still present in the solvent recovery system boiler is evaporated until the dirt becomes a thick concentrate. The solvent recovery system then switches off and is ready for manual or fully automatic emptying.
The distilled or purified solvent flows continuously from the solvent recovery system into the customer's on-site tank.
A very clever innovation for this solvent recovery system: A further feature of the ASC solvent recovery system is a slow-running scraper agitator with automatically adjusting scrapers made of PTFE. This unique doctor blade system for solvent recovery systems has been further developed over 30 years and is now used in the solvent recovery system for its robustness and cleaning efficiency. Two strong blades made of PTFE optimally clean the conical solvent recovery system vessel and do not have to be readjusted.
The doctor blades clean the solvent recovery system boiler wall over the entire filling area and not only at the boiler bottom like other solvent recovery system.
The contact pressure on the steep walls is optimal and large enough to prevent the build-up of deposits in the solvent recovery system.
The entire distillation process in the solvent recovery system is controlled by a SIEMENS SPS S7 1200. If the local requirements of the customer for his solvent recovery system change due to tanks, pumps or processes, the Siemens control system can be reprogrammed at any time and adapted to customer requirements and integration of the solvent recovery system. And this in national language bps. Chinese, Russian etc.! The OFRU solvent recovery system is multi-language ready.
The viscous residues are emptied by gravity via a slide valve at the lowest point of the conically round boiler of the solvent recovery system. The solvent recovery system can then be automatically refilled with contaminated solvent. A new continuous treatment process begins.
