Large Capacity 189L Ultrasonic Cleaning Tank 2400W 6000W Heating SUS304

The ST189A/B is built for the loads that decide whether a cleaning step is a bottleneck. Its 700 x 600 x 450 mm tank holds 189 litres, enough for complete engine assemblies, large pump bodies, heat exchanger bundles, gearbox casings, long hydraulic cylinders and full stillage baskets of small parts. 2400 W of ultrasonic power is distributed over the full tank floor so that a densely packed basket still cleans in one pass, and the 6000 W heater keeps a bath of this volume at temperature while cold parts are loaded. The three phase supply, braced chassis and heavy castors are specified for continuous operation in a production environment rather than occasional use.

• 189 litre working volume: A 700 x 600 x 450 mm cavity handles assemblies and bundles that do not fit smaller tanks, removing the need to disassemble parts before cleaning.
• 2400 W full floor ultrasonic power: Transducers cover the entire base rather than a central patch, which is what allows dense baskets and large single parts to clean in a single cycle.
• 6000 W heating capacity: The heater recovers temperature quickly after loading cold components, keeping cycle times predictable even when the tank is worked hard all shift.
• Frequency options for mixed work: Choose 28 kHz for carbon, scale and heavy grease, or 40 kHz when aluminium, plated parts and electronic assemblies need gentler cavitation.
• Sweep generator with safety transducers: Continuous frequency sweeping avoids standing waves and shadow zones, while the patented high voltage transducer design keeps the bath electrically safe and serviceable.
• Production grade construction: A reinforced frame carries a full tank without deflection, heavy duty castors take the loaded weight, and the integrated generator is rated for 24 hour 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.

Plants that clean large or numerous parts per shift use this size. Engine and transmission remanufacturers process complete blocks, crankshafts, camshafts and casings in one immersion. Hydraulic repair shops clean cylinders, rods, manifolds and valve blocks. Heat exchanger and compressor service companies remove scale and oil from bundles and rotor assemblies. Foundries and machine shops clean castings and welded frames before machining or coating, and contract cleaning operations run stillage baskets of mixed fasteners, fittings and small castings where volume matters more than individual fixturing.

The machine is crated in an export plywood case with the tank braced, the panel protected and all fittings capped. Delivery includes a stainless steel basket, lid, drain hose, spare fuse set and manual. Each unit is leak tested on all welds, run loaded for two hours, and checked for heater ramp, insulation resistance and frequency sweep before dispatch. A one year warranty covers generator, transducers and heater, with video diagnostics and stocked spare parts to keep downtime short.
