Large 20L Ultrasonic Cleaning Machine 400W 500W Heater Light Column Control

The GT SONIC-T20 steps up to a 500 x 300 x 150 mm tank, giving twenty litres of working volume and a long shallow working area that suits trays of parts laid out side by side. Complete cylinder heads from small engines, brake calipers, transmission valve bodies, pump assemblies, optical benches and full racks of machined parts fit with room to spare, and 400 W of ultrasonic power at 40 kHz is spread across the whole floor so a loaded tray cleans evenly. The 500 W heater holds twenty litres within the 20 to 80 degrees Celsius window through repeated loading, and the two stage switch covers both aggressive degreasing and gentler finishing work. Illuminated rotary knobs keep the control layout familiar across the series.

• Twenty litre shallow tank: The 500 x 300 x 150 mm cavity is laid out for trays and long assemblies, so parts sit in a single layer where cavitation reaches every surface.
• 400 W ultrasonic power: A high transducer count across the floor maintains cleaning intensity in a twenty litre bath, including the areas under a fully loaded basket.
• Two stage power switching: Operators choose maximum output for burnt oil, carbon and scale, or the lower stage for aluminium, plated finishes and thin walled parts.
• 500 W heating with sensing: Fast ramp and constant temperature control keep twenty litres at the set point between 20 and 80 degrees Celsius, even with cold parts loaded continuously.
• Illuminated knob control: Timer and thermostat are set through 360 degree light column knobs that stay readable across a workshop and can be turned with wet hands.
• Leak proof commercial build: New seam process, full leak testing and a rear main switch make the machine safe for daily commercial use and simple to isolate for service.

The T20 is aimed at workshops that clean assemblies rather than single parts. Automotive service centres clean cylinder heads, calipers, valve bodies, oil pumps and EGR assemblies; motorcycle and small engine shops process carburettor banks, crankcases and clutch packs. Industrial maintenance teams clean heat exchanger plates, small pump bodies, bearing housings and pneumatic components, optics and electronics shops clean long boards and chassis parts, and contract cleaners use it for mixed customer trays where one bath has to suit many part types.

The T series is covered by CE verification (T188066801 and T188066802), RoHS compliance (T188066803), FCC verification (T188103901 and T188103902) and REACH compliance (T188085501). Report copies are supplied with the shipping documents for customs clearance, tender submission and distributor registration, and the design is patent protected, so a repeat order matches the tested sample rather than drifting between production runs.

Units pack in a foam lined gift box inside a master carton with basket, lid, cord and manual, then palletise for container shipment. Testing covers a loaded two hour run, heater ramp, insulation resistance, tank leak and control function, recorded against the serial number. The one year warranty covers generator board, transducers and heater, with spare baskets, lids and knobs stocked.
