A Single tank cleaning system is most often used when only a small number of parts are cleaned. It is important to remember that you should use an industrial grade ultrasonic cleaning system, not one of the standard table top types. Most table top systems are very lightly constructed and have small transducers, with the generator, tank and heater in the same shell. These systems are used primarily for cleaning small parts, once or twice a day. They are not designed to provide high throughput or a high end clean part. Industrial Table Top Tanks always have the generator as a separate unit, this prevents damage by the heat generated in the ultrasonic tank and allows more room for larger transducers on the tank bottom.

Single industrial table top tanks can be set up to clean parts as well as a multiple tank system at far less cost. Of course there is no free lunch. A single tank system requires a manual cleaning procedure with full operator attendance. Another restriction is that you are limited by the size of a table top to smaller loads, especially if you are using a multiple beaker cleaning system where 3 or 4 beakers are placed in a holder and filled with cleaning and rinsing solutions. The parts are manually transferred from one beaker to another. Single tank systems are ideal for low volume, lab type or prototype cleaning lines.

AQUEOUS ALTERNATIVE TO SOLVENT CLEANING
The current Practice involves use of Chlorinated solvents like TCE, PCE etc. that are the choice solvent used through the industries in their cleaning process. Aqueous ultrasonic cleaners are very popular due to their good solvency, lower heat of evaporation, high or absence of flash point, non-corrosive nature, relative stability & compatibility with metals & glass. However all chlorinated solvents are hazardous to human health & environment.

Some chlorinated solvents are suspected to cause cancer (Carcinogenic) over prolong exposure. Being hazardous to health their usage has come under intense investigation from pollution control & health authorities & has already been banned by developed countries. This has lead to shift to alternative cleaning technology based on aqueous solvents.

Another factor driving the shift to aqueous cleaning is the environmental hazard caused by chlorinated solvents due to their Ozone depleting property. Due to this they have been targets of strong Government regulations throughout the world. It may be not long before similar legislation is introduced in India to phase out their usage.

AQUEOUS CLEANING TECHNOLOGY: THE ALTERNATIVE
Aqueous ultrasonic cleaners are environmentally benign, technically feasible alternative to solvent cleaning. The medium used for cleaning is predominantly water compounded with Alkali, Surfactants, Water conditioners, Corrosion inhibitors, Foam stabilizers etc.

Aqueous systems in many cases have replaced solvents without sacrificing cleaning performance. However due to the nature of solvent used, successful implementation of aqueous systems require a careful design effort necessitated due to the multistage operations involved like -
1) Cleaning with aqueous solution
2) Removal of contaminated solution with water rinse
3) Removal of water
4) Hot air drying

While solvent based cleaning primarily rely on chemical properties of the solvent, whereas aqueous cleaning systems rely on the mechanical properties like high-pressure spray, Ultrasonic agitation, dunking, etc. apart from the chemical properties of the aqueous medium. Therefore it is always recommended to have higher ultrasonic power per liter of volume. (Normally 16 to 20 watts per liter.)
