The S1 is our compact, single sump vapor degreaser. The S2 is our twin sump technology. The S2 is the system of choice for co-solvent cleaning applications. Both Solvac units come in 10x10 or 18x12 sizes and we also offer custom sizes where needed. Our patented Crest 132kHz ultrasonic sweeping technology provides the cavitation for strong cleaning of parts coupled with the solvent liquid. Our units offer low energy consumption with our vaportronic technology and minimizes solvent waste with our automatic sealed lid.
