Solvent Saver FLEXO Recycling Equipment

With Maratek's Solvent Saver FLEXO (SSF) 300 and 500 solvent recovery and recycling systems it's possible to minimize your costs while protecting the environment.

The solvents n-Propanol and Propyl Acetate are commonly used in Flexographic printing processes to clean printing equipment. They are often mixed with flexographic inks that can contain nitrocellulose which is combustible. Maratek can provide equipment to safely recover solvents for reuse and reduce your waste disposal costs.

With Maratek’s FLEXO line of products, you can expect to recycle up to 95% of your used flexographic solvents. This series of solvent recycling equipment processes solvent waste automatically with almost no operator intervention required.

Your waste solvent streams can be recycled efficiently and economically using the Maratek FLEXO solvent recycling units. In addition, these solvent recycling units are designed to integrate into your printing production process with ease.

Versatile Units with More Automation

The FLEXO 300 units can recover 300 gallons a day, while the FLEXO 500 units can recover 500 gallons a day. To find the right size for your application our team will assess the characteristics of your waste stream. Due to advanced automations, each system can operate virtually without an operator.

These rates are assigned according to the reference chemical, acetone, without any contaminants. The FLEXO units do not use bags and come with variety of useful automations. Internal mixers and scrapers are also used to manage waste buildup inside the vessel and assist with the discharge of viscous wastes.

Each system is equipped with glycol heating and high vacuum to minimize the temperatures required to prevent the combustion of nitrocellulose when present in the waste. As an additional safety feature, water quench is also included with these systems. 

All FLEXO units are fully constructed of 304 stainless steel. Both systems are water cooled and require a source of chilling water which can be provided by Maratek. 

The Maratek FLEXO units can be configured with different heating and condensing mediums, making these units extremely versatile. By selecting the appropriate options, these units can be tailored to fit the requirements of your waste stream.

Operating Principle

Maratek’s FLEXO 300 and 500 models separate solvents using the proven process of distillation, as described below.

  1. The waste solvent is automatically pumped into the distillation vessel. 
  2. The distillation vessel is fitted with a jacket of thermal oil that is heated by one or more electric heaters which brings the waste solvent to its boiling point. 
  3. Pure solvent vapor is then channeled to a condenser, where it cools into its liquid form. 
  4. The liquid is then directed to the clean solvent collection drums, where it can be re-used.
  5. As solvent is recovered new waste is automatically fed into the unit without operator intervention.
  6. Once the solvent recovery process is complete the waste sludge is automatically discharged to a waiting drum/tote below.
