Inner tank: Flexibility, economy, ultrasonic precision cleaning
Push-pull thickness mode ultrasonic transducers
Each transducer is comprised of a thin resonator rod with ultrasonic driver heads on each end. Its tall, thin design creates longitudinal pulses at a very high frequency with a near-perfect transmission of sound waves. Its sleekness also allows it to be placed into positions that are either extremely difficult or impossible to achieve with other designs. Learn more about our transducers.
Free-hanging for maximum power transfer
Each transducer emits 2,000 watts of ultrasonic power. By attaching the hanging transducers by a spring at the top (shown above) and a spring at the bottom (shown here), we ensure maximum transfer of power—which would be dampened if the transducers were firmly attached. This freedom creates more “action”—maximizing power flow along the tank bottom, sides, and surface. The loosened activity also creates natural air pockets that deflect the ultrasonic energy randomly, further ensuring complete sonic wave coverage.
Staggered inner wall placement for best power coverage
In addition to allowing random movement from the spring-and-ring hanging method described above, we also stagger transducer placements along the opposing inner tank walls. By purposely avoiding perfectly parallel placement—vertically and horizontally across from one another—we maximize power coverage around fouled parts within the tank during cleaning.
Placement along angled floor increase coverage and savings
In addition to along the inner tank sides, we run more transducers along angled edges along the tank floor. This dispenses ultrasonic cleaning power up and toward the center of the tank from below. The angled flooring also reduces detergent expanses and water resources by decreasing the total volume of liquid a 90-degree tank bottom edge would require.
Bottom rails support heavy parts, help slide sludge away
Two rails run along the length of the tank floor. These sturdy twin support rests can hold heavy equipment parts such as oil refinery heat exchangers and protect the tank bottom. They are also sloped slightly, using gravity to help loosened contaminates naturally fall away from the part as it is cleaned. The floor under the rails collects dense loosened waste that sinks below for easy removal after part is cleaned.
Overflow weir siphons away floating waste
Loose debris and lighter oils float to the surface as dirty parts are lowered into the tank and during the cleaning process. This floating waste naturally flows toward an overflow weir on one end of the tank, where it cascades over and down into two collection totes situated outside of the tank.
Adjustable, removable steam plates rapidly heat tank liquid
The steam plates located on the opposite end of the tank from the wire allow temperature adjustments, so liquid can be heated to any desired temperature at various time intervals. These plates are also individually removable, which in addition to affecting heating times also allows tank length to adapt to longer or shorter equipment parts. Temperature probes in the steam plates connect to the power cabinet’s Programmable Logic Computer (PLC) unit to monitor and adjust heating output—generally to maintain a temperature of 150°F. Fittings on the sides of each steam plate connect to the recirculation and filtration system to continuously recirculate water back into the steam plates. This completely eliminates the need to use more water or detergent once the tank has been filled.
Result: Precision cleaning, separation, and removal
After the equipment part is submerged, the operator activates the ultrasonic transducers that line the inner tank. The ultrasonic action and heated water-and-detergent solution safely break down the heavy, caked-on particles and gelatinous waste—which sinks to the bottom of the tank—as well as the lighter oils and particulates, which rise to the bottom of the tank and flow over the weir to the outer waste collection totes.
Crane lifts and tilts for loosened inner-part waste removal
When the immersed part is fully precision-cleaned, the crane operator will lift up and tilt the part so loosened debris will pour out of any tubes or openings. In fact, the operator can dip, lift, and tilt the part multiple times to fully flush any inner contaminants from the equipment part.
