Ultrasonic Cleaning Machine GT-ST20 SUS304 Stainless Steel Tank 20L with Digital Timer Control

The Ultrasonic Cleaning Machine GT-ST20 is a larger bench top cleaning platform for workshops, service departments and laboratories that need serious tank capacity in a compact body. A 40 kHz transducer set drives a 20 litre SUS304 stainless steel tank, producing a dense cavitation field that strips grease, oil, carbon, dust and oxidation from tools, hardware and precision components. Parts that would take an hour of manual scrubbing are cleaned in minutes, including threads, crevices and internal passages that brushing cannot reach.

The ST series is engineered for repeatable results. Time and heating temperature are dialled in on the digital panel, the loaded stainless basket is lowered into the tank, and the machine runs exactly the same cycle every time. Adjustable heating brings the cleaning solution to its most effective working temperature, while the corrosion resistant tank and drain valve make solution changes quick and clean. For maintenance teams, retailers and laboratories, the GT-ST20 delivers professional cleaning with minimal training and low running cost.

• 40 kHz Precision Cleaning: High frequency cavitation generates dense, uniform bubbles that clean fine details and blind holes without abrasive scrubbing or surface damage.
• 20 Litre SUS304 Stainless Steel Tank: The seamless, corrosion resistant tank stands up to daily alkaline and mild acidic detergents and handles a large basket of small to medium parts.
• Digital Timer Control: Cleaning cycles are set precisely on the digital display and shut off automatically, protecting delicate components from over cleaning.
• Adjustable Heating: The built in heater raises solution temperature to as much as 80 degrees Celsius, speeding up the removal of oil, wax and polishing compound.
• Stainless Basket and Drain Valve: A fitted basket keeps parts clear of the tank floor for even cleaning, and a drain valve empties the tank quickly between batches.
• Robust, Quiet Construction: A reinforced stainless housing and damped transducer mounting keep the unit stable, quiet and durable in continuous daily operation.
• OEM and ODM Support: Tank size, power rating, branding and panel language can be tailored for private label programmes.

The GT-ST20 suits any bench where parts range from heavily soiled to delicate. Tool rooms and machine shops use it to strip cutting oil, swarf and polishing residue from cutters, spanners, gears, bearings and machined parts. Electronics workshops remove flux and contamination from boards, connectors and stencils, while jewellery and optical benches clean frames, chains, lenses and watch components before display or repair.

Automotive service departments clean injectors, carburettor bodies, nozzles and brake parts in bulk, and dental or laboratory users rely on the same machine for instruments, small tools and glassware. Because one tank handles both general and fine cleaning, a single unit replaces a shelf of solvents and manual scrubbing tools, saving time, chemicals and bench space.

Each machine is packed in a foam lined colour box with the power cable, stainless basket and an English user manual, then protected by an export grade carton. Every unit is powered up, frequency tested, temperature verified and leak checked before dispatch, and it carries a one year warranty on the ultrasonic generator and transducers. Standard lead time is 15 to 25 days after deposit, with sample units available for evaluation. Please contact us to confirm tank size and voltage, or to request a quotation and OEM cooperation.
