CREST Optimum Console ultrasonic washing machine

Ultralsonic washing machine-The Crest Ultrasonics Optimum Console is a cost-effective, highly flexible solution for all industrial precision cleaning applications. Engineered with a compact, space-saving design and rugged, stainless steel tubular frame, it offers the convenience of an all-in-one, wash-rinse-dry design with a single-point facility connection for easy installation.


Versatile precision cleaning systems available in aqueous and semi-aqueous — manual, automated, and custom.

4- or 5-station designs available for immediate delivery

The 4-station wash-rinse-rinse-dry is ideal for cleaning at the microscopic level. And the 5-station wash-wash-rinse-rinse-dry system is configured for Dual Process or semi-aqueous precision cleaning applications. Standard tanks sizes (for manual and automated consoles) range from 10″L x 14″W x 10″D to 24″L x 36″W x 20″D. Custom tank sizes are also available.

Our manual Optimum Consoles are our base models, most commonly used in industrial applications where ultimate control in ultrasonic precision cleaning is not required, or where budget is an restraining issue over automation.

Every manual console includes:

  • Manually adjustable digital temperature and timing controls— Allows operator to set each independently, per wash, rinse, and dry station.
  • Smallest possible footprint— Saves space by maximizing compact design, with easy replacement of vapor degreasers.
  • 316L stainless steel tanks— For maximum wear resistance and lifespan.
  • Standard wire baskets— Available to fit inside each of our standard-size tanks.
  • GenesisTMgenerators — Patented, constant power provides TRU-SWEEP  sweep frequency cleaning action. Available in 25, 40, 58, 132, and 192 kHz frequencies, each designed for specific cleaning applications
  • Heated ultrasonic wash station(s)— Provides high-intensity heated ultrasonic cleaning with filtered recirculation with overflow weir to remove oil and particulate contaminants, which automatically maintains a cleaner solution.
  • Heated ultrasonic rinse station(s)— Provides two-stage, reverse flow cascade rinse with spray-over immersion, which conserves space and water usage, while maximizing rinses for spot-free drying.
  • High-efficiency recirculating hot air dryer(s)— With unique updraft air flow design to dry parts quickly with compressed air blow-off to allow speed and efficiency. (Much better drying solution than traditional ultrasonic cross-flow or convection drying.)
  • Sliding dryer cover— Promotes fast drying and protects against injury from flying particles.
  • HEPA-type filters— Removes microscopic particles during drying cycle.
  • Electrical control box— Conveniently located for easy access.
  • Single point utility connection— Fully plumbed and valved to single point for quick and easy installation.


Our automated Optimum Consoles are stock items based on our manual models, but drastically reduce the need for human interaction by replacing manual temperature and timing controls with Programmable Logic Control (PLC) operations. Upgrading to PLC provides significant benefits, including:

  • Programmable recipes — so your washes and rinses are timed perfectly each cycle. eliminating human error
  • Auto-advancing through the cycles — so your operators can spend more of their time on more important, more profitable tasks
  • Load Stations — With basket sensors to automatically activate transport and process cycle.

One type of “custom” Optimum Console we offer is a passivation unit for ultrasonically precision cleaning stainless steel. We call it our “made-to-order standard” console. A 5-station configuration of wash-rinse-passivation-rinse-dry, it allows you to remove iron residue that is introduced during the manufacturing of stainless steel, so the final cleaned items will not rust. We can produce your semi-custom passivation Optimum Console for either manual or automated operation, the latter of which uses our Programmable Logic Control technology.

Other than the semi-custom passivation unit, our custom ultrasonic cleaning equipment development offers truly one-of-a-kind consoles that adapt our basic system to:

  • as many stations as you want
  • with auto-forwarding from station-to-station
  • with manual or automated timing and temperature guages
  • in any size you need
  • to meet the demands of any production item, industry, or government standards in the world

Additional Accessories

Whether you elect to purchase a manual, automated, or custom Optimum Console, we offer you many optional equipment solutions to further adapt your console to your needs. We offer over 80 different items for maximum flexibility, so please contact one of our worldwide sales representatives to discuss all options that may suit your needs. But here are some of our most commonly ordered options for Optimum Consoles:

  • RoTumbler Rotating Basket System — Perfect for applications where fixturing is difficult or where parts tend to cup fluids. For loads up to 250 pounds. 
  • Closed Loop Water System— Environmentally safe, efficient recycling of rinse water for ultrasonic cleaning systems, spray systems and overflow rinse systems. 
  • Custom Fixtured Baskets— Uniquely configured for ideal cleaning of intricate parts.
  • Sliding Dryer Cover Automatic Activation— Reduces manual labor time, increases assured closer.
  • Oil coalescers/system replenisher — For cleaning applications that require ongoing removal of oil and other contaminants without interrupting the processing. Custom sized to fit system.
