Economical xtra ST Series

Elmasonic xtra ST Series Ultrasonic Cleaners

The 7-member xtra ST family comprises the workhorse units of Elmasonic industrial ultrasonic cleaners.  They’re found in shops handling a wide range of cleaning tasks – from grungy engine components to newly fabricated assemblies ready for painting, plating or further processing.  Splash-proof LED-equipped control panels tell at a glance what frequency is being used – 25 or 45 kHz – which functions are operating, and the status of cleaning cycles in terms of time and cleaning solution temperature.

The tank is equipped with two positions for hanging baskets facilitating loading products to be cleaned, and draining freshly cleaned loads while conserving cleaning chemistries by returning them to the tank.  Cleaning tasks are further eased because the Elmasonic xtra ST units can be rolled to the site – requiring only a source of electric power.  Models are equipped with lockable wheels to keep them in place when on site.

Elmasonic xtra ST industrial ultrasonic cleaners are easy to operate and easy to maintain. If service is needed, simply swap out the control panel/generator assembly cutting down time to a minimum.  The new generator automatically tunes itself to the transducers. They come with a 3-year tank warranty (for single shift operation).

Available Peripherals

Elma Filter Extends Cleaning Solution Life

The Elma Filter Option prolongs cleaning solution effectiveness by monitoring and removing contaminants and fine particles during cleaning cycles. Benefits: extended bath effectiveness, lower water consumption and reduced tank erosion from settled particles. When flow rate decreases due to contaminant buildup, filter cartridges are easily replaced by shop personnel. Elma Filter is available as an option on all newly purchased Elma xtra ST units offered by Tovatech or can be retrofitted on your existing xtra ST equipment.

The Elma Rinse option can be table or wall mounted and is equipped with two rinsing wands, one for tap and one for demineralized water.
