Workshop Grade 288L Ultrasonic Cleaning Machine 3000W 7000W SUS304 Tank

The ST288A/B is the largest standard model in the ST series and is aimed at plants that treat cleaning as a production station rather than a support task. An 800 x 600 x 600 mm tank holds 288 litres, which covers complete engine assemblies, large gearboxes, industrial pump sets, motor housings, long shafts and pallet sized baskets of components. 3000 W of ultrasonic power and a 7000 W heater are matched to the volume so that a heavily loaded tank still cleans in a predictable cycle, and the deep cavity allows parts to be immersed upright without dismantling. Three phase power, a load rated frame and heavy castors are standard.

• 288 litre deep tank: The 600 mm depth and 800 x 600 mm opening accept upright assemblies and pallet baskets, so large parts no longer need to be broken down before cleaning.
• 3000 W ultrasonic coverage: A high transducer count across the full tank floor maintains cavitation density in a bath of this size, including the corners that smaller designs leave dead.
• 7000 W heater with insulation: Fast ramp and quick recovery after loading keep the bath within the working window even when the machine runs continuously through three shifts.
• Selectable 28 kHz or 40 kHz: The A version drives heavy carbon removal, the B version protects machined surfaces and fine features, and both share the same tank and controls.
• Stepless power and sweep cycle: Output can be dialled down for delicate parts, and continuous sweeping removes standing waves that otherwise leave shadow areas behind ribs and baffles.
• Heavy duty industrial platform: The frame is designed for a full tank load, the castors handle the working weight, and the integrated generator is rated for 24 hour continuous duty.

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.

Heavy equipment, marine, rail and power generation maintenance departments run this size. Workshops immerse complete engine blocks, large gearboxes, hydraulic power units, turbocharger assemblies, motor casings and long propeller or drive shafts. Industrial cleaning contractors use it for customer parts that arrive on pallets, and pump and compressor rebuilders clean housings, impellers and rotor assemblies before reassembly. Foundries and heavy fabrication shops remove core sand residue, cutting fluid and mill scale from large castings and weldments before machining or painting.

Shipping uses a heavy export plywood case with internal bracing to hold the tank and frame, the panel protected by a foam face and the drain fittings capped. The package includes a stainless basket, lid, drain hose, spare fuses and a manual. Each machine is weld tested, run loaded for two hours, and verified for heater ramp, insulation resistance and frequency sweep, with the test record tied to the serial number. The one year warranty covers generator, transducers and heater, supported by video diagnostics and stocked service parts.

Send the largest part dimensions, the load weight and your required cycles per shift, and our engineers will confirm the 288 litre platform or quote a custom tank and handling system.
