Aqueous System Helps Clean Up the Process :: The high-temperature, ultrasonic, vacuum dry, aqueous vapor degreaser saved this manufacturer more than $30,000 in the frst year of use. Te vapor degreaser did not consistently clean the chill rings to the degree of cleanliness required. Te company searched for a solution for several years before Executive V.P. and General Manager Chuck Szeglin contacted MecWash Systems. "We ran cleaning trials with a number of wash equipment companies, but none of their systems performed consistently better than our vapor degreaser. Tat is, until we started working with MecWash." System Meets Needs After three rounds of cleaning trials, Kinemotive ordered the MecWash AVD, a high-temperature, ultrasonic, vacuum dry, aqueous vapor degreaser. When paired with MecWash System's cleaning chemical AC-32, this aqueous cleaning system can remove almost any contamination Kinemotive encounters, whether it is water- or mineral-based. Although Kinemotive still has its original vapor degreaser, they do not use it often. "Since we installed the MecWash system, we use the vapor degreaser to clean only a small subset of our parts," Mr. Szeglin says. "Tis has allowed us to drastically reduce our solvent purchases, which has saved us a lot of money." Because Kinemotive requires such demanding cleanliness standards for its components, the confguration of the MecWash equipment installed at the company is a bit unusual. Te company tests bellows sensors for functionality in silicone oil at high heat. Afterward, these components are taken to the cleaning system. Silicone oil is a tenacious oil to clean from metal surfaces. After this sensor testing, silicone oil becomes deeply embedded into the bellows, making the component difcult to clean. MecWash Systems devised a process whereby these bellows sensors are frst cleaned in an ultrasonic dunk tank built into the framework of the AVD that contains 100-percent AC-32 chemical at 140°F. After the sensors are exposed to this ultrasonic bath, they are then moved to the wash chamber to be cleaned using ultrasonic wash and rinse, food wash and rinse, and spray wash and rinse cycles. Te cleaning process concludes with a 285°F hot air blow dry and a deep-drawn vacuum dry to ensure that all moisture is pulled out of the now-contracted chill rings of the bellows. Another special requirement of this system is that the rinse tank water must be absolutely pure at all times, with no contamination at all. To achieve this requirement, MecWash installed its water polishing circuit. Tis polishing circuit purifes the entire quantity of water in the rinse tank in 15 minutes—less than the time needed to run one complete cleaning cycle.
