Esma’s automatic ultrasonic passivation systems offer a compact, closed-loop solution for cleaning, rinsing, passivating, and drying parts, all at the push of a button. Designed for in-house use, these systems minimize fumes, reduce floor space requirements, and deliver significant cost savings compared to robotic alternatives. With a “we move the fluids, not parts” approach, Esma ensures safer, more efficient processing. Standard tank sizes are available, and custom configurations are common. Complementing the equipment, Esma’s proprietary ultrasonic cleaning solutions are formulated to clean and passivate a wide range of metals, including stainless steel, aluminum, and copper, even in complex geometries.

Esma’s multi-tank ultrasonic cleaning and passivation systems offer a flexible, in-house solution for medical and industrial applications requiring precision cleaning. These manual systems guide parts through a sequential process—heated cleaning, DI rinsing, passivation, and drying, with digital timers to assist operators. Compatible with both citric and nitric acid, they’re ideal for facilities seeking cost-effective alternatives to automated lines. Available in standard and custom tank sizes, Esma systems are supported by proprietary ultrasonic cleaning solutions formulated for a wide range of metals and complex geometries.

Esma ultrasonic cleaners combine precision engineering with rugged stainless steel construction, offering models from compact 1-gallon benchtop units to large 350-gallon floor systems. Powered by proprietary solid-state circuitry, each unit delivers consistent square-wave frequency and automatic tuning for uniform, high-performance cleaning, even in hard-to-reach areas. Esma also provides custom tank sizes and specialized ultrasonic cleaning solutions formulated to remove residues without damaging surfaces, helping improve throughput and finish quality across industrial and medical applications.

ESMA’s automated ultrasonic cleaning systems redefine efficiency by moving liquids, not parts, through each cleaning phase, resulting in lower costs, reduced footprint, and safer operation compared to robotic gantry systems. With over 40 years of expertise, ESMA offers both standalone and integrated units in standard and custom sizes, featuring PLC controls, heated storage tanks, and multi-stage cleaning, rinsing, and drying cycles. From compact 3.5-gallon models to advanced passivation systems, each unit is designed to deliver consistent, high-quality results. ESMA’s proprietary ultrasonic cleaning solutions further enhance performance across a wide range of metals and industrial applications.

Esma’s non-automated ultrasonic cleaning systems feature multi-tank designs in single or multi-chassis configurations, offering dedicated chambers for ultrasonic cleaning, hot water flush rinsing, and hot air drying. With models ranging from compact benchtop units to larger console-mounted systems, Esma delivers versatile solutions for precision cleaning across industries. Durable stainless steel construction, consistent amplitude control, and optional features like pump filters ensure high-quality results for applications including optics, circuit boards, jewelry, and machined parts. Paired with Esma’s specialized cleaning solutions, these systems provide efficient, reliable performance for demanding environments.

Esma’s automatic ultrasonic washers and tabletop cleaners feature a proprietary in-tank tumbling system that enhances cleaning performance by rotating parts during the ultrasonic cycle. This motion dislodges debris from blind holes, separates clustered components, and eliminates trapped air, allowing ultrasonic cavitation to reach all surfaces. Integrated into fully automatic systems, the tumbling action also accelerates rinsing and drying. Built with durable stainless steel and backed by a one-year warranty, Esma’s rotational cleaning systems offer a cost-effective solution for surgical, laboratory, and industrial applications, especially when paired with Esma’s non-abrasive ultrasonic cleaning solutions.
