ASC-Series Professional Solvent Recycling
ASC-type units, comprising some of the most modern distillation plants worldwide, are compact in design, powerful, and very easy to operate.
The OFRU distillation plant ASC was specially developed for custom- ers with large quantities of soiled solvents, e.g. 300-30.000 l/day. The plant is equipped with a conical distillation vessel in stainless steel and an integrated high capacity steam generator for powerful distillation (beginning with ASC-150). The heat is produced with electrical energy 380-410 Volts. Alternatively, other heat carrying media (e.g. oil/hot wa- ter) can be attached. The plant is normally connected to tanks for soiled and purified solvents.
An Ex-proof level control system retains a constant solvent quantity inside the evaporator system and guarantees continuous 24hr-opera- tion. A vacuum pump conveys the soiled solvent into the evapora-tor. A vacuum unit reduces the boiling temperature and thus prevents undesired decomposition of the solvent and pollution. Solvent vapours are condensed inside the water-cooled condenser and are collected in a tank, for reuse.
A slow-moving scraper device, with self-adjusting scraper blades, maintains the vessel walls free of crust formation during distillation. The combination of a uniform stirring and perfect scraper blades on the side wall of the vessel ensure for optimum heat transfer into the solvent. The result of such construction details is a fast heating-up of the solvent and a high solvent output, even with a compact machine size and ves- sel/filling volume.
The whole distillation process is controlled and monitored by a SIEMENS microprocessor. At the end of the continuous operation the automatic sump distillation process is started. The residue is thickened to a predetermined viscosity, controlled by a timer. Afterwards, the plant is automatically switched off and ready for drainage. The drainage of the viscous residues occurs via a sliding valve at the bottom end of the conical vessel. The rotating scraper and the conical vessel design provide for easy drainage of the sludge through the centered outlet of the vessel. Manual cleaning duties are no longer necessary.
The plant is then ready for the next continuous operation.
ASC- type units comprise professional and easy-to-operate solvent recovery plants for high volumes, 300-30.000 l/day. Obtain the best performance
■ Fast and powerful heating-up of the machine. This saves time and money.
■ High outputs possible (litres per hour)
■ Constructed acc. to latest EU directives: High levels of operational safety
■ Low space requirement
