Model SRU-30 to SRU-265 - Vacuum Distillation/ Solvent Recycling Unit



The filling of the units SRU-30 to SRU-265 takes place fully automatic and is controlled by filling level regulation. At the end of the process the distillation residues are treated up to the desired residual solven rate. Therefore, almost unattended 24-hour operation is possible.

Instruments in the front panel inform about process pressure, solvent gas temperature and heating temperature of the unit. The discharging of the residues is done via the user-friendly cleaning aperture, which ensures safe operation due to an integrated O-ring seal.

The unit is equipped with switching cabinet and PLC controll unit. The control unit ensures the desired process flow and monitors the compliance of all safety relevant parameters. 

The vacuum unit reduces the boiling point of the solvent, avoiding thermal decomposition of the solvent. At the same time the energy consumption is decreased, solvent yield, performance and distillate quality as well as operation safety are greatly increased. Additionally the process under vacuum (and therefore the absence of oxygen) offers a improved explosion protection and a more favorable ex-zone classification.
