OFRU Recycling from Babenhausen in Germany is optimising its product range in preparation for the DRUPA 2012. The main focus is on the ASC-150 recovery plant with 24 kW heating capacity. The ASC-150 solvent recovery plant is the smallest model in the professional ASC series which has an integrated steam heating system. The steam heater in the double jacket of the distillation vessel was developed by OFRU as long ago as 1997, and replaces the conventional thermal oil heating system for solvent recovery plants.

The optimisation of the ASC-150 for flexo printing shops drew on the experience and wishes of the customers. Packaging and flexo printing shops wish to integrate the solvent recovery directly into the automatic washing process of a modern printing press on the one hand and to incorporate older printing presses into the recovery process on the other.

At the DRUPA 2012, OFRU will therefore be presenting a solvent recovery concept linked to an ASC-150, two stainless steel solvent tanks with UN and DOT approval (approved in particular for hazardous liquid substances of classes 3, 4.2, 4.3, 5.1, 6.1, 8 and 9). The two tanks can be connected online to a printing press and ensure continuous processing of the solvents.
In addition, a solvent filling and discharge station has been integrated. At the push of a button, the printer can also transfer the soiled solvent from a drum into the tank, or pump clean solvent from the second tank when necessary for manual washing processes. This solution is particularly practical, as many printing shops still employ older printing presses and have not yet changed over to printing presses offering an automatic washing process.

Experience has shown that the distillation capacity of this plant is sufficient for 30 to 65 litres per hour with a heating temperature of only 100-110°C. The low heating temperature is necessary to ensure safety during the distillation of nitrocellulose-based solvents.

The processing concept presented already forms part of the OFRU product range for 2012.

OFRU Recycling GmbH & CO. KG (www.ofru.com) is a medium-size family company based in Babenhausen at the edge Rhine Main Frankfurt area. The enterprise was created in the year 1978 and looks back today on 33 years experience in the distillation technology of solvents. Today OFRU is a leading global manufacturer of highly productive solvent recycling and recovery machines (Solvent recovery systems, distiller); solvent recycling plants for distillation solvents.

The product program covers modern distillation systems and/or vacuum distillation plants for inflammable and aqueous solvents and/or cleaners. Beside the small plants for 50 l daily volumes, fully automatic evaporators up to an output of 2000 l/hr are available.

Recycling and reclaiming systems recycle, recover a variety of solvents. Almost all flammable solvents. Examples of alcohols include ethanol, isopropyl alcohol, n-butanol in the ketones: acetone, methyl ethyl ketone, methyl isobutyl ketone, esters with ethyl acetate, with the aromatics: toluene, xylene, to name only the most important. Typical solvents include ethyl acetate in packaging printing and flexo printing in ethanol, toluene in gravure and all known organic solvents for washing the flexographic printing plates / sleeves in analog prepress.

The success bases on a comprehensive process engineering know-how in many industries and a modern development department. Technical innovations and safety is a huge priority with OFRU. Clients are based all over the world, mainly in environmental, chemical, printing and industrial sector.
