Harper Scientific, the printing and coating supplies division of global anilox supplier Harper Corporation has introduced the Promag magnet with bracket.
Without the heater, the ultrasonic vibration heats the cleaner to about 120 degrees Fahrenheit - a temperature that is claimed to provide excellent results.
The new cleaner's surfactant technology is claimed to be environmentally friendly, using no petroleum distillates, or environmentally hazardous chemicals.
It is a biodegradable, low-vapour pressure and low-VOC cleaner.

Environmentally friendly new cleaner developed for on-press use
Available exclusively through Harperscientific, the super-concentrated formula, which can be diluted with water, is sold in four-packs of 32oz bottles, pails and drums.
Jim Doedderlein, technical sales specialist for Harperscientific, said: "We were thrilled to get reports from customers that they found great success using UV Re-Leez as a solvent ink cleaner for anilox and gravure cylinders in ultrasonic tanks.
We've had reports that customers are cleaning press sleeves in ultrasonic tanks and cleaning the between-station dryer assemblies the same way." And Jim Harper, vice president at Harperscientific, added: "In a case where the air diverters on the drum side of the dryer were clogged with ink, the customer used UV Re-Leez in the ultrasonic tank to clean them and the operator called to tell us the dryers looked like new.
Another converter ran its ultrasonic tank with UV Re-Leez to clean chrome and copper gravure cylinders and said it was the best stuff they have seen." As a result of the reports, Harperscientific conducted its own corrosion and efficacy tests on UV Re-Leez that indicated the product is indeed, safe and effective for ultrasonic tank use.
A one-week soak test found that UV Re-Leez is non-corrosive for aluminum, said the company.
Tony Donato, Harper Corporation's process and product development engineer, commented: "We talked to ultrasonic tank manufacturers who indicated that until now there has not been an ultrasonic cleaner that is aluminum-safe.
In addition, a gravure user told us that cleaning a roll covered with cold seal adhesive with their former cleaning solution in the ultrasonic tank gave off a very foul odour that filled the whole plant.
But UV Re-Leez cleans the cold seal roll without any noxious smell.".
