Sweep Mode

Evenly distributes cleaning power throughout the solution for consistent results.

Pulse Mode

Adds bursts of ultrasonic power for intensive cleaning and degassing of tough contaminants.

Dynamic Mode

Combines Sweep and Pulse modes for optimum cleaning results on a wide range of parts.

Industrial-Grade Construction

Robust stainless steel tanks with long service life. Wheel-mounted for portability. Designed for continuous operation under the highest operational demands in production environments.

Timer

Timer adjustable from 1 to 30 minutes or continuous operation. Automatic shut-off at 90°C or after 12 hours of continuous operation for safety.

Heater

Temperature adjustable from 30°C to 80°C with automatic start-up.

Drain System

All models feature drains with stainless steel ball valves for easy maintenance and cleaning solution changes.

Easy Servicing

Control panel/generator assembly can be quickly removed and replaced in-house. Intelligent generators adjust automatically to transducers. Made in Germany with UL, CSA, ISO9001, and ISO13485 certifications.

Frequently Asked Questions

When should I choose xtra ST instead of benchtop industrial models?

Choose xtra ST when your parts are larger, your throughput is higher, or you need floor-standing tanks designed for production-duty cleaning.

How do I size the right xtra ST model?

Measure the largest part you need to clean, then compare those dimensions to the basket and tank dimensions. If you run multiple parts per cycle, size up for spacing and consistent cavitation.

Can xtra ST handle heavy soils like polishing paste and machining residue?

Yes. Dual-frequency operation plus Sweep, Pulse, and Dynamic modes are designed for difficult industrial soils while maintaining repeatable cleaning quality.

Do I need filtration with xtra ST?

For high-volume production cleaning, filtration is strongly recommended to extend bath life, reduce downtime, and stabilize cleaning results.

What chemistry should I run with xtra ST?

Use ultrasonic-safe chemistry matched to your soil and substrate. Verify concentration and temperature guidance before production runs.

Will it damage the tank if I set it to run continuously and forget to shut it off?

No. The Elmasonic xtra ST models will automatically shut off after 12 hours of continuous operation. This protects the tanks and any parts left in the tank. The unit will also shut down for safety if the temperature reaches 90°C.

Do these units have UL or CSA electrical certification?

Yes, the xtra ST models have UL and CSA certification.
