Single Tank 53L Industrial Ultrasonic Cleaner 900W with 2000W Heating SUS304 Tank

The ST53A/B opens the ST series with a 53 litre working volume that suits workshops running mixed batches of metal, glass and electronic parts through one tank. A 500 x 350 x 300 mm cavity takes long shafts, small gear sets, PCB carriers and hand tools in a single load, while 900 W of ultrasonic energy and a 2000 W heater bring the bath up to the set point without a long wait. The generator sits inside the chassis, so the machine only needs a power connection and a drain before it starts working. Because output is adjustable from 0 to 100 percent, the same unit can strip polishing compound from brass fittings at full amplitude and then switch to a gentler setting for anodised aluminium or delicate instrument parts fitted with plastic seals.

• Reinforced SUS304 tank: The cavity is formed from 2.0 mm imported SUS304 stainless steel, welded, ground and passivated so that aqueous alkaline detergents do not attack the seams during years of daily use.
• Stepless power control: Ultrasonic output runs from 0 to 100 percent, letting an operator match cavitation intensity to the part rather than to the tank, which protects thin walls, plated surfaces and soft soldered joints.
• Selectable frequency: The A version works at 28 kHz for heavier soils such as carbon, polishing paste and burnt oil, while the B version runs at 40 kHz for finer cleaning of small bores and blind holes.
• Sweep generator and safety transducer: A second generation sweep circuit spreads the resonance point instead of holding a single peak, and the patented high voltage transducer arrangement removes dead zones in the tank corners.
• Efficient 2000 W heating: The heater reaches 30 to 110 degrees Celsius with insulation around the tank, so the bath holds temperature with less element cycling and lower energy draw over a shift.
• Built for continuous work: Medical grade swivel castors, a rigid frame, an integrated generator and a continuous duty rating let the machine run through back to back loads without cool down intervals.

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 53 litre platform is the usual choice for job shops that clean under a hundred kilos of parts per shift. Typical loads include hydraulic fittings, valve bodies, machined brackets, mould inserts, cutting tools, bearing housings and small welded assemblies before painting. Electronics workshops use it for populated boards, stencils and solder frames where 40 kHz keeps fragile traces safe. Tattoo studios and piercing suppliers rely on it for instrument trays and grips. Jewellery repair benches use the tank for rings, chains and watch cases after polishing, and automotive service points clean injector components, EGR valves and small transmission parts before inspection.

Every machine ships in a plywood case with foam blocks around the tank, the castors braced and the drain valve protected, together with a basket, a lid, a drain hose and an operation manual. Each unit is pressure tested, run for two hours with a load, and checked for transducer bonding and heater response before packing, and the serial number is recorded against the test sheet. The warranty covers one year on the generator, transducers and heater, with remote diagnosis by video and spare transducers, fuses and gaskets kept in stock for fast dispatch.

Send us the parts you plan to clean and the throughput per shift, and our engineers will confirm whether the 53 litre tank is the right size or recommend the next model in the series.
