RST: solvent distillers

Our distillers allow the recovery and reuse of the used solvent, separating the polluting product (paints, inks, etc.) from the original solution. In other words, they recycle a hazardous waste material in a safe and environmentally friendly manner.

Sustainability

The distilled solvent is reusable, thus significantly reducing the cost of consumables. It is environment-friendly and reduces disposal costs.

Process

The operation is based on the evaporation of a liquid into a gas in order to separate the substances without altering the characteristics of the product. This process is carried out by applying heat and is based on different boiling points. The solvent is evaporated from the polluting products, condensed and finally directed to a tank in the form of a clean and reusable solvent. The polluting products remain at the bottom of the distillation tank and are easily disposed of. This operation can be carried out repeatedly without the solvent losing its properties.

Two Models

There are two models of RST distillers to meet the most common needs.

Characteristics of the models:

  • They comply with the ATEX safety regulations (explosives)
  • Solvent purchases are reduced by 90%
  • The need to handle the solvents and move them around the facilities is eliminated
  • Continuous cleaning of the internal boiler walls (contributing to efficient heat transfer and the mixing of the solids)
  • Automatic cycle (no supervision required by the operator)
  • Control by PLC throughout the process.
  • Vacuum pump with a liquid ring (enabling work at a lower temperature and energy savings; the solvent is further from the self-ignition point due to the temperature)
  • Easy access to the boiler and tanks for maintenance and cleaning.
