Benchtop Ultrasonic Cleaner Sizes from 1.3 L to 30 L: Tank Dimensions, Power and Which Series

A benchtop ultrasonic cleaner can have enough litres on the label yet leave your largest part sticking out of the liquid. It can also fit the bench while adding an electrical load nobody checked. What use is extra capacity if the basket cannot take the part? Start with the inner tank dimensions, then compare ultrasonic power, heating power and the controls your process needs.

This guide compares Jietai’s tabletop ultrasonic cleaner sizes from 1.3 L to 30 L. For a toolroom, laboratory or quality department, the useful shortlist comes from the actual load: part geometry, basket space, batch size and available electrical supply.

Compare tank dimensions and power before choosing a capacity

The table brings together the listed capacities and models. Slash-separated powers and adjustable ranges represent alternatives in the model group; they do not mean every model has every setting. Match the exact model to its specification before ordering. Browse the benchtop cleaner range with your basket dimensions beside you.

Read L × W × H against the basket and largest part

Measure the largest part in its intended cleaning orientation. Compare the basket’s outside dimensions with the tank, then compare its usable inside dimensions with the parts. Basket walls, supports and the arrangement of the load consume space; the tank dimensions are not the basket dimensions.

The part must be completely immersed at the permitted operating liquid level. Tank height includes space that may not be available for immersion, while the basket can raise the part above the tank bottom. Request the basket dimensions and operating fill guidance rather than treating the full tank depth as usable part height.

A 2 litre ultrasonic cleaner has a listed tank of 150 × 140 × 100 mm. The 1.3 L tank has the same length and width but a depth of 65 mm: 100 − 65 = 35 mm less tank depth. Buying by litres alone hides that distinction.

The same issue matters farther up the range. Both 10 L and 14 L tanks are 300 × 240 mm across, while their depths are 150 and 200 mm: 200 − 150 = 50 mm additional tank depth. Likewise, 22 L and 30 L share a 500 × 300 mm footprint; the larger capacity adds depth, not length.

For a lab ultrasonic cleaner, ask whether the whole intended basket load fits, not merely an individual specimen. If the required working space exceeds this benchtop range, assess single-tank industrial cleaning equipment rather than assuming a larger benchtop model exists.

Separate cleaning power from heating power

Ultrasonic power and heater power are separate ratings. Neither the larger heater rating nor the larger litre figure proves that a particular contaminant will be removed.

For comparison, the fixed ultrasonic entries give 180 W ÷ 6 L = 30 W/L and 600 W ÷ 30 L = 20 W/L. Those ratios describe listed power per nominal capacity. They are not measured cleaning results, and an adjustable model’s ratio changes with its setting.

The summed ratings help frame a supply enquiry, but they are not a substitute for the complete machine’s input specification. Ask which exact model and power setting the quotation covers. An adjustable-power entry in this table should never be treated as a feature of every machine at that capacity.

A German toolroom: check the complete load before ordering 30 L

For the buyer with 230 V single-phase power and a 16 A circuit, the 30 L row provides a starting point: 600 W ultrasonic + 600 W heating = 1,200 W. Where the exact model has the listed adjustable ultrasonic range, its lower endpoint gives 240 W + 600 W = 840 W. The upper endpoint gives 600 W + 600 W = 1,200 W.

These are sums of the listed component ratings, not verified maximum mains input. We would request the exact model’s maximum input rating, whether heater and ultrasound can operate together, and any supply requirements before purchase. Also identify other equipment sharing the circuit.

Confirm the offered voltage and single-phase configuration when requesting a quotation; they are not specified in the listed product details. Confirm certification and supporting documentation at the same stage. Could a component-power sum alone tell you whether your existing circuit is suitable? Have the actual input specification and shared circuit checked before accepting that conclusion.

A Spanish workshop: size for the optical-mount batch

For the buyer in Spain cleaning 100 optical mounts a day on 230 V single phase, the daily count does not establish tank size. You need the mount dimensions, intended basket arrangement and number that can be cleaned together. Establish an acceptable cleaning process in trials before using it to plan daily throughput.

A 6 litre ultrasonic cleaner offers a 300 × 150 × 150 mm tank; a 10 L unit offers 300 × 240 × 150 mm. The width difference is 240 − 150 = 90 mm, with no increase in tank depth. Shortlist the smaller tank if the complete loaded basket fits; consider the wider tank if the arrangement needs that width.

Using the fixed ultrasonic entries, their component sums are 180 W + 300 W = 480 W and 240 W + 300 W = 540 W. Confirm the exact model’s complete electrical input and supply configuration. The Spanish enquiry specifies no circuit rating or shared loads, so neither option can be promised to avoid tripping.

To turn 100 mounts a day into a tank size, use two numbers from the trial rather than guesses: parts per validated batch, and the full batch turnaround time including loading, cleaning, rinsing, drying and any cooling pause. Batches needed = 100 ÷ parts per batch, rounded up; time needed = batches needed × turnaround time. Compare that with the working time available that day. If the 6 L basket meets the result and the daily time, it is the candidate; the 10 L tank is only worth choosing if its wider basket actually adds parts per batch or fits a part geometry the 6 L cannot.

Why a 10 L cleaner might overheat during repeated cycles

The reported pattern is shutdown after three consecutive 8 min cycles at 70°C: 3 × 8 min = 24 min of cleaning time. Both heating and ultrasound can raise liquid temperature. A temperature setting does not provide active cooling, and closely spaced cycles can leave accumulated heat in the bath.

This mechanism makes heat accumulation worth checking; it does not identify the shutdown cause. The listed specifications do not state thermal protection thresholds, duty limits or restart conditions. Do not infer those values from the thermostat’s adjustment range.

Check the actual liquid temperature against the setting, and observe whether it keeps rising during ultrasound operation.

Check the liquid level and loaded basket against the exact model’s operating instructions.

Review ventilation and whether the heater continues contributing heat between cleaning cycles.

Ask the supplier about permitted duty, protection behaviour and restart instructions; evaluate a cooler starting condition or pauses only through controlled trials.

Record what stops: only the ultrasound, only the heating, or the whole unit, together with any display message and the liquid temperature at that moment. If the shutdown is a protective response, do not bypass it or keep restarting until the cause is established.

What differs between the six benchtop series?

The product descriptions give concrete differences in controls and timer ranges. Each lists a 20 to 80°C adjustable thermostat and stainless-steel inner tank and outer shell. Confirm additional construction details and performance claims against the exact model specification.

Mechanical Series: a 0–30 min mechanical timer and mechanical thermostat.

Digital Black Titanium Series: a 0–30 min digital-display timer and digital-display thermostat. The listed tank and shell material is stainless steel despite the series name; the product page also lists a degassing function and a full/half-wave function.

Smart Digital Three-Frequency Series: a 1–99 min digital-display timer and digital-display thermostat. The product page lists 40, 80 and 120 kHz as selectable frequencies, with the option of stepping through them automatically in sequence.

Dual-frequency machine: a 0–30 min digital-display timer and digital-display thermostat. Its name identifies dual frequency; confirm the actual frequency options when enquiring.

Digital Multi-Functional Series: a 1–99 min digital-display timer and digital-display thermostat. Request the exact function list rather than inferring it from the name.

Digital Power Adjustment Series: a 0–30 min digital-display timer and digital-display thermostat. Confirm the exact model’s power adjustment range against its quoted specification.

Use the ultrasonic cleaning frequency guide to frame selection questions, then verify the offered settings. A series name does not establish cleaning suitability for your part.

Jietai Ultrasonic has made industrial ultrasonic cleaning equipment since 2003 and has its own factory in Dongguan. To narrow the shortlist, request a free cleaning test using your own parts. Describe the contamination, your planned basket arrangement and the cleaning result you need. Use that trial to inform the capacity and series discussion; agree separately on any additional testing you need.
