Available Options

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.

Elma Rinse Achieves Spotless Results

Use the Elma Rinse with tap water to remove heavy, loose contaminants before ultrasonic cleaning to help prolong cleaning solution life.  After the items have been cleaned, spray rinse products with demineralized (DM) water provided by the included filtration system, to remove remaining residues. 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.
