Product information
Tieser vacuum distillation unit solvent series DIstatic type DV 25 AX - LCD
The Tieser vacuum distillation unit solvent with stainless steel cooler (INOX) of the Distatic series are available with optional capacities of 12, 25, 60 and 120 litres. They are suitable for recovering and reusing the contaminated solvent from cleaning and degreasing processes.

Process description:
By utilising simple distillation, contaminants (such as resins, polymers, pigments, paints, oils, etc.) are separated from the original solvent. The soiled solvent is boiled in a stainless steel vessel (Inox AISI 304). Uniform heating takes place via a heating jacket made of heat transfer oil, which is heated by one or more heating rods. The solvent vapours produced are fed into an air- or water-cooled condenser. The condensed solvent is collected directly in a container for subsequent reuse. In the case of liquid soiling, the residues are emptied by simply tipping the tank. For solid soiling, use a heat- and solvent-resistant foil bag. The solvent properties are not changed by the distillation, so that the process can be repeated as often as required. All systems can be equipped with a vacuum group. This mode of operation can be used for solvents with very high boiling temperatures or for flammable solvents with close boiling and spontaneous ignition temperatures. The vacuum can be generated pneumatically or electrically, depending on requirements.

Additional instructions for pneumatic vacuum vessel:
A compressed air supply is required for distillation systems with a pneumatic vacuum vessel. This must be dry and oil-free, reach a pressure range of at least 6 bar and generate a minimum air flow rate of 450 l/min (for the duration of the vacuum build-up).
The vacuum is set at the factory between -0.5 and -0.7 bar negative pressure, depending on the system type.
The vacuum vessel is automatically pressurised with compressed air. The distillation vessel and the vacuum vessel are now vented (placed under vacuum) via the Venturi nozzle and the set vacuum of -0.5 to -0.7 bar is created. The process is accompanied by a clearly audible "hissing" sound. As the vacuum approaches the set value, the "hissing" becomes much quieter. The pneumatic vacuum valve now keeps the vacuum constant throughout the distillation process. Depending on the tightness of the overall system, this can occasionally lead to short refilling processes (a few seconds) of the vacuum.
