CliniEco Ultrasonic Cleaner — 20 L Bench Unit, CS20 with Heater and Drain Valve

Quick answer: A 20 L chamber with eight transducers, 500 W of ultrasonic power and 500 W of heating — built for a clinic running several chairs, or a laboratory cleaning in batches.

At 20 L the tank stops being a bench accessory and becomes a station. The chamber is 42 × 26 × 20 cm, the unit is 54 × 37 × 40 cm and weighs 17 kg dry, and eight transducers are distributed under the floor so coverage holds across the full length rather than concentrating in the middle. It can sit on a counter or be installed recessed into one, which is usually how a multi-chair clinic handles a tank this size.

Scope of use. This is a cleaning device. It removes soil — cement residue, polishing paste, dried blood in hinges and threads — as a step in instrument reprocessing. It makes no microbicidal claim, and it does not replace any later step in the workflow set out in the instrument manufacturer’s instructions for use. The Health Canada guidance on reprocessing information is why the instrument manufacturer’s instructions — not the cleaner’s specification sheet — decide what happens to a given instrument after it comes out of the tank.

What are the CS20 specifications?

The two numbers that decide an installation are the loaded weight and the footprint: a 20 L working volume is roughly 20 kg of water plus a 17 kg unit.

Which tank size in the range fits your room?

This is the largest unit in the range and it is not the right unit for a two-chair practice. The sizes below it cover one chair, one cassette, or two chairs in one cycle; 20 L is for a room where the tank runs continuously or where instruments arrive in bulk.

Plan the bench before the unit arrives. A loaded 20 L tank is about 37 kg on a 54 × 37 cm footprint, and it needs to sit within reach of a drain or a container you are willing to carry. Recessing it removes the lifting problem and is the reason this model has a noise-reduced cabinet.

How do you run a repeatable cleaning cycle on the CS20?

A tank this size changes the workflow question from ‘does it fit the bench’ to ‘who owns the cycle’. One person should own the fill level, the solution change interval and the log.

The failure mode on large tanks is drift: the level drops as baskets come out wet, someone tops it up with water, and after a week the concentration is half what the label says. Keep a marked fill line and change solution on a schedule, not on appearance.

What an infection-control inspection asks for is the record, not the machine. Ontario’s provincial reprocessing guidance asks for documentation and maintenance of records for each component of the cleaning, disinfection and/or sterilization process, based on the manufacturer’s recommendations, and repeats that records must be retained according to the facility’s policy (Public Health Ontario, “Best Practices for Cleaning, Disinfection and Sterilization of Medical Equipment/Devices In All Health Care Settings”, 3rd edition, checked 2026-11-07). A unit with a drain valve, a visible timer and a stable temperature set-point is what makes that record short enough to write at the end of a shift.

What does the cETL mark cover, and what does it not?

The CS20 sits under a different Intertek report from the smaller units — 260210005GZU-001 — which is the number to quote if a technician or an inspector asks which certificate covers this family. The mark on the unit is an ETL mark issued by Intertek, tested against UL 73 and CSA C22.2 No. 68. It is an electrical safety certificate. It is not a UL listing and it is not CSA certification, and it says nothing about how well the tank cleans. Canadian reprocessing practice sits on a separate standard, CSA Z314:23, whose scope puts documentation inside the reprocessing quality system rather than inside the appliance.

What is in the box, and what should be ordered with it?

One cleaner, 20 L, 110 V with a North American plug and the manufacturer warranty. Basket as an accessory. Because the unit can be recessed, confirm the cut-out dimensions with us before the bench is built rather than after.

Multi-enzyme ultrasonic cleaning solution is what goes in the tank, sold as a 1 L bottle or a 5 L pail and diluted 1:400 to 1:600. The 6 L CS6.2 is the unit to look at if your load grows into full cassettes. Read how to choose a tank size and what to record on the cleaning log before you commit to a size.
