Model SRU-30 to SRU-265 -Solvent Recycling and Vacuum Distillation Units

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.
