Heavy Duty 105L Ultrasonic Cleaner Tank 1500W 4000W Heating Unit SUS304

The ST105A/B is the point where the ST series turns into a true production tool. Its 600 x 500 x 350 mm tank holds 105 litres and accepts parts that previously needed a multi tank line, including engine blocks from compact vehicles, transmission housings, large manifolds, welded frames and full racks of machined components. 1500 W of ultrasonic power drives cavitation across the whole floor of the tank rather than only around the centre, and the 4000 W heater keeps a large bath at temperature while cold parts are dropped in. The frame is stiffer than the smaller models, the castors are heavier duty, and the integrated generator is rated for continuous production shifts.

• Production sized 105 litre tank: A 600 x 500 x 350 mm cavity takes engine blocks, gearbox housings and long fabrications, and the flat floor makes basket loading and sludge removal straightforward.
• 1500 W distributed ultrasonic power: Transducers are bonded across the entire tank base, so a full basket of parts cleans evenly instead of needing to be shuffled around during the cycle.
• 4000 W heating for large baths: The heater holds 105 litres at working temperature with margin to spare, which prevents the slow temperature sag that stalls cycles when cold parts are added.
• Dual frequency architecture: Order the A version at 28 kHz for heavy carbon and rust removal, or the B version at 40 kHz when machined surfaces, aluminium and electronics need a gentler bath.
• Adjustable amplitude and sweep cycle: Output can be reduced for thin section parts, and the sweep generator continuously shifts the resonance point to eliminate blind spots behind ribs and inside pockets.
• Continuous duty industrial frame: Reinforced chassis, heavy castors, an integrated generator bay and a 24 hour duty rating let the machine keep pace with a two or three shift operation.

Model suffix A denotes the 28 kHz configuration and suffix B the 40 kHz configuration. Both versions share the same tank, heating system and generator platform.

This size is common in remanufacturing, engine overhaul and general industrial maintenance. Workshops clean stripped engine blocks, cylinder heads, oil coolers, turbo housings, transmission casings, differential parts and brake components before inspection and rebuild. Fabricators use the tank to remove cutting fluid, mill scale and welding residue from frames, brackets and formed sheet parts before powder coating. Aviation and rail maintenance shops clean overhauled components, and PCB assemblers use the 40 kHz version for stencils, pallets and frames. Food and beverage plants clean stainless fittings, valves and pump parts with a compatible detergent.

Units ship in a heavy plywood case with internal bracing, the control panel protected, the drain valve capped and the castors secured. The package includes a stainless steel basket, lid, drain hose, spare fuse set and manual. Each machine runs a two hour loaded test, a heater ramp test and an ultrasonic sweep verification, and the test sheet travels with the serial number. The one year warranty covers generator, transducers and heater, and consumable parts such as gaskets and fuses are held in stock for quick shipment.
