Distillation Unit ASC-500 37 kW

Functional description of the solvent distillation units 
The ASC-500 37 kW is an extremely comfortable vacuum distillation unit from the professional ASC series. It has a modern integrated steam heating.

Heating of solvent distillation units ASC-500
A special feature of the distillation units is the conical stainless steel distillation vessel or boiler, in which the shell surface is heated with steam. The distillation units heating steam in the double jacket transfers the heat extremely quickly to the solvent. At the same time, high distillation performance is achieved with a small boiler volume.

The distillation units have a clever design. Only one electrical connection is required for the integrated steam heating of the distillation units. A high performance liquid ring vacuum pump conveys the dirt into the distillation units and guarantees continuous 24 hour operation. During automatic distillation in the unit, the evaporated amount of solvent is automatically replenished by the addition of dirt into the distillation unit. This automatic continuous distillation mode can be set by timer.

Distillation units safety function:
If the dirt tank of the customer contains no more solvent, the distillation units receive a signal and automatically switches to "sump distillation". The continuous filling into the distillation units is stopped and the amount of solvent still present in the distillation units boiler is evaporated until the dirt becomes a thick concentrate. The distillation units then switches off and is ready for manual or fully automatic emptying.

The distilled or purified solvent flows continuously from the distillation units into the customer's on-site tank.

Perfect scraper system in ASC-500 distillation units

A further feature of the ASC solvent distillation units is a slow-running scraper agitator with automatically adjusting doctor blade made of PTFE. This unique doctor blade (scraper) system has been further developed over 30 years and is now used in our solvent distillation units for its robustness and cleaning efficiency. Two strong scrapers made of PTFE optimally clean the conical evaporator vessel in the solvent distillation units and do not have to be readjusted. The doctor blades or scrapers clean the boiler wall over the entire filling area and not only at the boiler bottom like other solvent distillation units.

The contact pressure on the steep walls is optimal and large enough to prevent the build-up of deposits in solvent distillation units.

Flexible process in distillation units and adaptation to customer requirements:
The entire solvent distillation process for the distillation units is controlled by a SIEMENS SPS S7 1200. If the local requirements of the customer change due to tanks, pumps or processes, the Siemens control system can be reprogrammed at any time and adapted to customer requirements for the distillation units integration. And this in national language bps. Chinese, Russian etc.! OFRU distillation units are multi-language ready.

Discharging the distillation residues in ASC distillation units:
The viscous solvent residues in the distillation units are emptied by gravity via a slide valve at the lowest point of the conically round boiler. The distillation units can then be automatically refilled with contaminated solvent. A new continuous distillation process of solvents begins.

ASC-100 12 kW

Functional description of the solvent recovery system 
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.

Heating of the solvent recovery system ASC-100
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.

Filling of the solvent recovery system
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.

Solvent Recovery System Safety Function
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.

Perfect Scraper System in the solvent recovery system
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.

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.
