Omegasonics’ Viking line of multi-stage ultrasonic cleaning stations is designed for cleaning precision parts and components in the aerospace, dental, medical, pharmaceutical and microelectronic industries. Multi-stage ultrasonic cleaners are usually three- or four-stage systems. In a three-stage unit, the ultrasonic cleaner, rinsing station and drying station are built into a single housing so parts can be moved quickly from cleaning process to cleaning process. Some four-stage units include a pre-wash station ahead of the ultrasonic cleaner. This is a necessary step for manufacturers that need to remove loose scale, grease, oil or dirt before placing parts in the ultrasonic cleaner, the company says.
For flexibility, the Viking line includes three models with increasing stage capacities, including the X2, DX3 and DX4. The X2 offers the choice of two stages between ultrasonic wash, heated rinse and ultrasonic rinse; the DX3 offers the choice of three stages and adds a hot air dryer to the options; and the DX4 houses all four stages (ultrasonic wash, heated rinse, ultrasonic rinse and hot air dryer). The high-efficiency dryer is contained within the system to maximize space. Stainless steel tank sizes range from 18" × 18" × 14" to 24" × 36" × 20".
Each system includes digital temperature controls, digital timer control for the ultrasound wash, dual-stage filtration during the wash stage, single-stage filtration during the rinse stage and low-level float sensors during all stages. The washers are designed for portability, with built-in casters and a single point of connection for utilities. They are made of corrosion-resistant materials and coated with a Hammerton powder finish. In addition, the company says that its machines do not include automation in order to be an economical option for small- to mid-sized businesses.
