How does an aqueous parts washer work?

An aqueous parts washer is a safe and effective waste-based solution that, unlike petroleum- based solvents, are typically non-flammable and contain little or no VOCs. It is an alternative to solvent parts cleaning and eliminates the need for harmful cleaning solutions. Aqueous parts washers use water-based chemicals. Instead of dissolving grease and solids, aqueous cleaners rely on heat, agitation, and soap action to break dirt into smaller particles.

. Because they clean differently than harmful solvent-based cleaning, an aqueous parts washer reduces the release of VOC (volatile organic compound), which cause lung problems and other medical issues. Aqueous parts washers can improve parts cleaning in your operation and reduce the creation of hazardous waste.

How do you select an Aqueous Parts Washer?

Aqueous parts washers can last longer than solvents, but careful consideration must be made in order to extend the life of an aqueous solution. There are traditionally two types of aqueous cleaning units: microbial sink top and spray cabinets. You can read about these strategies on the EPA website. Today, dynamic manufacturers and other specialty shops now use immersion and ultrasonic cleaners. In this post, we'll cover immersion parts cleaners.

Immersion Parts Washing Methods

Immersion parts washers are preferred for parts that must be partitioned and placed in baskets for longer processing, in order to remove contamination deeply within the pits and grooves of the part. Immersion cleaning exposes all surfaces of the part, and as such, it is the most effective method, even if not the fastest one. It can be aused with virgin cleaning solvents as well as aqueous detergents, heated (aqueous only) or at room temperature.

There are four types of immersion parts washing methods:

1. Soaking

Soaking is the simplest, least aggressive cleaning action but requires more time so that the sludge and chemical waste can be fully removed.

2. Turbo Fluid Agitation

This is a faster method than manual soaking and requires constant movement of solutions in order to work through and around the soiled parts. A variety of pump circulated parts washing systems are available for fluid agitation.

3. Lift Platform Agitation

This type of “scrubbing” action is achieved by continually moving the parts through vertical oscillation and agitationThis method is fully automated and further intensified when used in combination with Turbo fluid agitation.

4. Heated Solution (water-based solution only)

The effectiveness of water-based cleaning solutions increases dramatically as the temperature increases. The optimum recommended temperature is governed by the equipment and the particular detergent used.

By combining hands-off, total immersion cleaning with easy loading, Solvent Recycling Systems offers the most advanced immersion parts washing available.
