APPLICATION
Our systems with automatic operation are capable of reprocessing all organic solvents in outstanding quality. By applying the special LÖMI vacuum technology, our systems are capable of reprocessing organic solvents with a boiling point of up to 250 °C. Integration into existing purification processes is possible in a fast and economical way.
Advantages
- Consistent cost savings
- Minimisation of disposal costs
- Minimisation of stockkeeping
- Minimisation of in-house handling
- Rapid amortisation
- Recovery rate up to 99 percent
- Consistent production quality
Vacuum distillation is used for reprocessing the solvent: The distillation can be carried out at lower temperatures, as the vacuum leads to a decrease in the boiling point of the solvent. This reduces the energy requirement and thus the operating costs. The lower temperatures have a number of positive side effects: firstly, thermal decomposition of the solvent is prevented, secondly, foaming due to possibly contained water is reduced. In addition, when reprocessing cleaning media with nitrocellulose lacquer components, process temperatures of less than 100 °C can be guaranteed.
ECONOMY LINE
These systems are characterised by extensive standardisation, low investment costs and a short lead time.
CUSTOMISED LINE
Tailor-made high-end systems that are individually adapted to your process. With comprehensive configuration variations, we can satisfy any of your requirements.
ECONOMY LINE: VDA / VRA

FAQ
An in-house solvent recovery system is profitable starting at 25 litres of used solvent per day.
For quantities of more than 200 litres per day, the amortisation of a solvent treatment plant usually occurs within one year, for smaller systems after about two years.
The distillation can be carried out at lower temperatures, as the vacuum leads to a decrease in the boiling point of the solvent. This reduces the energy requirement and thus the operating costs.
The lower temperatures have a number of positive side effects: firstly, thermal decomposition of the solvent is prevented, secondly, foaming due to possibly contained water is reduced. In addition, when reprocessing cleaning media with nitrocellulose lacquer components, process temperatures of less than 100 °C can be guaranteed.
