AUTOMATIC CLEANING AND SOLVENT RECYCLING SYSTEM
I
RAC S.r.l. started its activity of solvent use and recovery 25 years ago, when the “distiller” was still designed as a response to the small business management problems. During the following two decades, it has transformed and increased the response capabilities of its equipment by preferring some constructive choices to others and by enhancing the capability and versatility of its products. IRAC aims at all those market segments where the solvents, be they flammable or not, including water, are the only or the best way to wash, degrease, clean. One of the company’s flagship systems is the specific tank for cleaning 30 l commercial cans, combined with an automatic distiller type PAIL-WASH DISTI COMBO 1100. The washing tank is made entirely of stainless steel AISI 304 and allows the use of both flammable and non flammable products. The control panel is pneumatic. The average cycle length is between 8 and 12 minutes: its duration is influenced by the amount and the fluidity of the ink, as well as by the type of solvent used.
The inside of the can undergoes a washing process whose quality is ensured by special high liquid flow rotary heads, while the process liquid is recycled. The tank is equipped with a device for the discharge of the dirty solvent by means of a pneumatic pump and with a suction hood to remove any vapour through a Venturi system. The T working dimensions are: a max 3x 30 l commercial cans, 1100 x c 500 5 x 500mm. A solvent distiller is automatically connected with the tank, so as to create a “washing/recycle” closed circuit. This automatic system draws the exhausted solvent from the tank, regenerates it through distillation and reintroduces it into the tank, a without stopping the washing w process. The number of washing p ccycles after which the solvent must be recycled can be regulated. The b plant is designed to work both with p and without vacuum, thus making it possible to treat every solvent on the market. For further information: www.irac.it
