A “one of a kind” process
Since 1972 Esma Incorporated has been manufacturing high quality ultrasonic cleaners and washers as well as benchtop electropolishing equip-ment. Esma offers a unique approach to automating the ultrasonic cleaning process by transferring liquids to a single ultrasonic process cham-ber from individual heated storage tanks. These tanks are designed to re-use and filter the detergents, acids and rinse water.
This approach has been especially effective in cleaning applications which use dangerous chemical such as those used in passivating stainless steel. By moving the fluids and not the parts, the entire system can be closed with each storage tank covered and vented. The cover of the process unit, which also acts as the dryer, can be vented to exhaust any chemical fumes out of the work environment. PLC and HMI touchscreen controls give the oper-ator full access to program changes and data, which can be recorded for process validation and control.
“We move the liquid NOT the parts”
Multi-tank and benchtop ultrasonic cleaning equipment complete the ultrasonic cleaner line.
Esma also manufactures a line of benchtop electropolishing equipment and corresponding electropolishing solutions. Our electropolishing solu-tion for cobalt chromium has been recognized for its excellence throughout the world and is used to electropolish stents for many major medical manufacturers.
