Large Ultrasonic Cleaners          

Zenith Ultrasonics manufactures large ultrasonic cleaners for the cleaning of heavy and big components with light or heavy contamination.  Large tanks are usually required to clean parts such as:

  • Plastic Injection Molds
  • Aerospace components
  • Large batches of smaller parts
  • Bulk rebuilding of firearms
  • Heat Exchangers
  • Engine blocks

What do I need to consider when purchasing a large ultrasonic cleaner?

When dealing with large liquid volumes and ultrasonic cleaners, there are several considerations:

  • Tank Integrity:  The tank needs to be able to withstand the pressure of the liquids and the weight of the parts being cleaned.  This requires a specific tank design that moves the stress points away from welded edges.
  • Ultrasonic Power:  There needs to be enough ultrasonic power to provide the cleaning performance you need.
  • Ultrasonic Frequency:  The frequency chosen will usually be in the low frequency range when cleaning heavy parts, or Zenith's patented CROSSFIRE Multiple Frequency Ultrasonic System operating at 25 and 40kHz.
  • Heating Systems:  Large tanks may require extended time to heat to operational temperatures due to the large liquid volume in the tank.
  • Filtration Systems:  Need to be large enough to remove the dirt being removed from the parts, and push to dirt towards to filter system suction port.  Filter housings and pumps need to be larger.
  • High-volume Oil Skimming:  When removing greases and oils, a high volume oil skimmer with the ability to isolate surface oils from the cleaning tank is needed to prevent oils from re-depositing onto parts when they are removed.

How large can the ultrasonic cleaning tank be?

The only limitation is the size of your parts.  Tanks from 1000-3500 gallons in size have been manufactured by Zenith.  At 3500 gallons, a small car could fit into the tank.  This gives you an idea of how large ultrasonic cleaning tanks can be.  If you already have an existing tank, Zenith can supply immersible transducer systems to provide ultrasonic cleaning action to your existing tanks.

How many tanks do I need for my application?

If you already have a way to rinse and dry your parts, you would need only a single ultrasonic cleaning tank sized to fit the load of parts you intend to clean.  If you need rinsing and/or drying, these tanks can be included in the system.  The upper photo to the right includes dual ultrasonic cleaning tanks and a single ultrasonic rinsing tank with internal tank dimensions of 72" x 48" x 40" tall.

What standard sizes are available?

The 2 largest standard sizes include baskets which are 24' x 36" x 24" tall, and 36" x 48" x 36" tall.  Larger systems are available and are custom-designed to suit your specific application, and customization is no extra charge at Zenith.
