Roll Up Your Sleeves

Sandy Mueller, technical sales representative at Daetwyler, stresses that proper usage eradicates the chance of damage with ultrasonics. Users should ensure that the roll is rotating during cleaning, and that the solution in the tank cavitates, or bubbles, well. Newer systems offer adjustable sweep frequencies. A table-top ultrasonic unit can run as low as $500, while a complete system for extremely large rolls could cost up to $50,000, Mueller estimates.
