Aqueous Parts
Cleaning Systems

In the demanding world of manufacturing and MRO (maintenance and repair operations), machinery up time, production efficiency, and product quality are crucial in ensuring an organization’s success. Aqueous cleaning systems play an integral role in a manufacturer’s ability to deliver quality parts in a repeatable, efficient manner.

Aqueous parts washers are specialized cleaning systems that utilize water-based solutions (often combined with detergents, specialized chemistries, and heat) to remove tough contaminants like grease, oil, grime, and machining residues from a wide array of parts. They come in various designs to suit different applications and part sizes.

“Jenab’s aqueous cleaning systems are reshaping industrial cleaning with an eye on the future. As regulations tighten and efficiency demands grow, we are focused on ensuring our systems deliver. We routinely see manufacturers cut cleaning times by a third while slashing chemical costs in half.” – Jim Chew, CEO

How Aqueous Cleaning Systems Work

Aqueous cleaning systems provide a safe and environmentally conscious alternative to solvent-based parts cleaning. Their cleaning effectiveness comes from the unique interplay of these key components:

1. The Cleaning Chemistry

Aqueous solutions rely on water as their primary solvent. This foundation is further optimized through carefully selected additives:

• Detergents. These work much like dish soap, breaking down and emulsifying oils and greases, allowing them to be lifted from the part’s surface.
• Builders. These soften water and optimize the effectiveness of the detergents for enhanced cleaning power.
• Specialized Additives. These components provide tailored benefits. Rust inhibitors protect ferrous metal components, dispersants break down solid particles, and biocides maintain solution health by preventing bacterial growth. These components provide tailored benefits. Rust inhibitors protect ferrous metal components, dispersants break down solid particles, and biocides maintain solution health by preventing bacterial growth.
• Temperature. Aqueous cleaning solutions generally work best at elevated temperatures (up to near boiling), as heat softens contaminants, reduces surface tension, and speeds up chemical cleaning reactions.

2. Cleaning Action

• Spray Nozzles. Parts are blasted with high-pressure jets of heated solution. This direct force physically dislodges surface contaminants and washes them away.
• Immersion & Turbulence. Fully submerging a part ensures the solution reaches all surfaces. Pumps and mechanical movement create turbulence within the cleaning tank, further breaking down and flushing away grime.
• Mechanical Action. Parts washers often provide greater cleaning power through:
  • Basket Rotation: Gently tumbling parts allow for full exposure of all surfaces to the cleaning solution.
  • Agitation: Vertical agitation while submerged creates agitation that helps dislodge solids.
• Ultrasonics. This highly effective technique uses high-frequency sound waves to create microscopic bubbles in the solution. These bubbles implode violently (a process called cavitation), creating a scrubbing action that reaches into even the most complex crevices and internal structures.

3. Cleaning Action

An essential part of the cleaning process involves maintaining a clean process solution by adequately removing soils. Aqueous parts washers employ filtration systems to:

• Remove Particulate. As contaminants like oils, dirt, and metal shavings are removed from parts, filters continuously trap and remove them. Filtration systems range from simple mesh screens to sophisticated multi-stage setups, ensuring the solution doesn’t redeposit debris onto cleaned parts.
• Skim oil. Many washers integrate oil/water separators, like oil coalescers or skimming belts, to continuously remove floating oils and greases. This significantly extends the useful life of the cleaning solution, minimizing maintenance requirements and reducing waste generation.

4. Rinsing & Drying

The final steps in aqueous parts washing focus on eliminating cleaning solution residue and ensuring proper drying:

• Rinse Stages. Many cleaning systems utilize rinsing, oftentimes more than a single stage. Effective rinsing ensures no chemical residue remains that could interfere with downstream processes or the part’s final use while improving reliability, appearance, and overall part quality.
• Drying. In many applications, thorough drying is critical for post cleaning operation processes or to prevent the formation of contamination spots. Common drying methods include:
  • Recirculating High Volume Air. Heated air is forced across parts through an air delivery device (air knives, nozzles, manifolds), and continuously recirculated to effectively shear and evaporate remaining liquid.
  • High-Pressure Blow-Off. High pressure blow-off systems rely on blowers that deliver significant pressures to shear excess solution from the part system rather than relying on heat to dry.

Aqueous parts washers come in diverse configurations to accommodate different cleaning needs, space constraints, and budgets. Below are the most common types.

Cabinet Washers

Cabinet washers are enclosed machines where parts are cleaned in a dedicated chamber using spray nozzles and sometimes high-pressure jets. There are several variations of cabinet washers. Jenfab generally breaks these down as two types including:

1. Front Loading
   1. PCS
   2. HDS
   3. Vertical Door
2. Top Loading

Both Front-Load and top-load industrial cabinet washers share similar cleaning processes:

• Loading. Parts are manually loaded onto a basket or turntable inside the cabinet. When the application requires it, these systems can be fully automated.
• Cleaning Cycle. The chosen cleaning solution is pumped and sprayed throughout the chamber, dislodging contaminants. This can involve multiple wash, rinse, and dry stages depending on the application.
• Unloading. Once the cleaning cycle is complete, the door is opened, and the parts are removed.

Selecting a parts washer can be a daunting task with the number of different machine types available. When you speak with a Jenfab representative, we will gather the details on your application and work with you to determine the optimal solution for your unique problem. The decision about which wash system to invest in goes beyond its core cleaning capabilities. To get the most out of your system, it’s vital to consider numerous factors.

When choosing the optimal aqueous parts washer, consider:

Part Size & Geometry: Size, weight, and complexity dictate washer type and chamber dimensions. Measure the largest part you anticipate cleaning – not just length/width, but the full 3D space it occupies. Tank, tunnel, or process chamber dimensions directly limit what fits. A few oversized parts justify larger units, while small components often do well with batch washing.

• Ensure the washer easily handles your largest parts and provides ample space for loading and movement within the cleaning chamber.

Materials of Compatibility: Equally important is material compatibility. The cleaning solution you choose must be formulated for the metals, plastics, or other materials present in your parts to prevent any damage. It’s crucial also to verify that the washer itself – the tank, internal components, seals, etc. – can withstand the chosen cleaning chemistry without deterioration. The material of the components you are cleaning could limit the types of cleaning process or cleaning solutions that will work with your application.

Environmental regulations and your company’s sustainability goals deserve careful attention. Ensure your chosen system adheres to all local and federal environmental regulations regarding VOC emissions, wastewater discharge, and disposal. Some industries, like healthcare and aerospace, face even stricter requirements. Even where not strictly mandated, choosing an aqueous system naturally aligns with environmentally responsible manufacturing practices.

Production Volume: Batch vs. continuous processing influences model choices. For maximum efficiency, assess whether your workflow benefits from batch cleaning, individual part washing, or a system designed for continuous, inline parts processing. Plan for potential growth in production volume or changes to part complexity, as these may impact your initial washer choice.

• One-offs vs. Batch Cleaning: Low volume favors simple setups. Continuous process lines may call for conveyor models.
• Cycle Time Matters: Do you need one part done ASAP, or is leaving a tank running while other work happens acceptable? This influences features like heated solutions, aggressive spray action, etc.

Automation Requirements: The level of automation plays a significant role as well. Determine whether manual loading and unloading are feasible or if an automated washer would bring significant gains in productivity and labor savings. For processes with strict standards, automated washers, and programmable cycles ensure reliable, repeatable cleaning results.

Required Cleanliness Level: Understanding the contaminants being removed and how to deal with them once removed is critical in specifying the proper cleaning sys
Operating Costs. Don’t overlook long-term operational costs. Compare upfront prices across systems, factoring in the cost of detergents, additives, and any wastewater treatment needed. Include utility usage (water, heat, electricity), labor savings associated with automation, and preventative maintenance.

The Next Step in Manufacturing: Is the part immediately going to final assembly? Drying methods (heated blow-offs, etc.) matter, as do temporary rust inhibitors incorporated into the final wash cycle. If you are prepping for Coating/Plating specialized washer chemistries and rinse setups ensure surface pre-treatment needs are met, guaranteeing later bonding processes succeed.

Your Facility’s Space and Size

• Floor Space Available: When selecting an industrial parts washer, look beyond its footprint to ensure adequate surrounding space for loading/unloading parts, servicing the unit, and moving materials with lift equipment. Careful measurement of these peripheral floor space needs will help optimize the installation process.
• Ventilation & Fume Control: Heated units, and certain detergents require air exhaust to stay safe, possibly taking up room and factoring into setup costs.
• Electrical & Utility Constraints: Match a washer’s power demands to what your space has. Upgrading old wiring becomes an add-on cost!

Aqueous Parts Washer Fluid: What Type of Fluid Do They Use?

The Role of Water Quality in Aqueous Parts Washers

The effectiveness of an aqueous parts washer is multi-faceted. Cleaning systems rely on a combination of mechanical action, exposure time, temperatures, and the water-based cleaning compound being used.

This starts with the quality of the water itself. Hard water supplies can cause scale build-up within the parts washer and leave behind residue deposits on the parts being cleaned. Softened water, or in stringent applications the use of RO or DI water, help ensure spot-free parts and minimize potential system build-up.

While water quality is an integral part of the process, choosing the correct chemistry (or wash compound) is essential in achieving optimal performance. Chemistry works in conjunction with mechanical action and heat to deliver consistent results. The machine provides heat and agitation; it’s the chemistry that gets the tough work done.

While solvents once dominated the cleaning scene, they have by and large been restricted by legislation. Aqueous solutions present undeniable advantages across a spectrum of concerns. Beyond environmental compliance, a well-chosen aqueous washer brings tangible benefits to worker health, process efficiency, and even your bottom line. If you are still working to find a solvent alternative for your cleaning operation, please reach out to us for assistance.

Aqueous Cleaning Solutions & Their Applications

Aqueous cleaning solutions are formulated to tackle specific contaminants and to ensure compatibility with diverse part materials:

• Alkaline Cleaners: Alkaline solutions excel at removing particulate matter, oils, and certain surface oxides.
• Rust Inhibitors: Protection for ferrous metals is vital. These additives can be included in the cleaning solution or in rinse stages to prevent flash rust from forming on freshly cleaned parts.
• Specialized Additives: This broad category includes anti-foaming agents (necessary for vigorous agitation or high-pressure spray), rinse aids, and biocides that prevent bacteria or microbes from ‘spoiling’ the cleaning solution.

Chemistries: These fluids come in various formulations and concentrations to cater to diverse cleaning requirements. Here’s a breakdown of some key aspects:

• Composition: The primary component in most any cleaning chemistry is water. The water is then blended with detergents, surfactants, and corrosion inhibitors depending on the application.
• Cleaning action: While water itself doesn’t dissolve oil and grease, detergents and surfactants act as emulsifiers, breaking down these contaminants into smaller particles for easier removal.
• Biodegradability: Look for formulas labeled biodegradable for a more environmentally responsible choice.

Selecting the most suitable aqueous parts washer fluid depends on several factors:

• What Part Material is Being Processed? Different materials may require specific cleaners: Parts manufactured from aluminum or copper alloys might be more prone to pitting than ferrous metal parts, requiring different cleaning fluid formulations.
• What Part Material is Being Processed? Different materials may require specific cleaners: Parts manufactured from aluminum or copper alloys might be more prone to pitting than ferrous metal parts, requiring different cleaning fluid formulations.
• What Soils are Being Removed? Similarly to the part material, the soils being removed have an impact on the appropriate cleaner and concentrations. The chemistry used to remove heavy scale, rust, and road grime from remanufactured ferrous transmission components is going to be formulated differently than what would be used to clean light oil from newly manufactured titanium fasteners in the aerospace industry.
• Partner with Experts: Suppliers like Jenfab offer solutions tailored to common scenarios and can guide you based on your parts and contamination levels.
• The Importance of Rinsing: Prevent dried spots and residue issues by having appropriate rinse stages or tanks included as part of your cleaning system.
• Thorough Testing: Always trial new solutions with sample parts, looking for efficacy and any potential material incompatibility.
• Maintenance Matters: Keeping your tank clean, your liquid filtered, and your operating concentrations within range will maximize long-term cost-effectiveness.
• Remember: Waste disposal guidelines evolve, so consulting local authorities and obtaining expert guidance from your solution supplier is a cornerstone of safe and compliant aqueous cleaning.

Always follow the manufacturer’s instructions for handling and using aqueous parts washer fluids. By understanding the type of fluid used in aqueous parts washers and making informed choices based on your specific needs, you can ensure efficient and safe cleaning of your parts.

Keeping your solution working at its peak involves a few key actions:

Safety and Operational Guidelines

Aqueous parts washers offer a significant safety advantage over solvent-based systems. However, it remains crucial to implement safety protocols and best practices in your operations. These measures contribute to operator safety, optimal equipment performance, and environmental compliance.

Your primary safety reference for any cleaning solution is the Material Safety Data Sheet (MSDS). It details potential health risks, recommended handling precautions, storage methods, and what to do in case of accidental exposure.

Based on the MSDS guidance, choose appropriate Personal Protective Equipment (PPE). Gloves, eye protection (goggles or face shields), and chemical-resistant aprons are often necessary to prevent solution contact with skin and eyes. Adequate ventilation, especially when using heated solutions, prevents excessive vapor buildup.

You can also consult your Jenfab solution provider if you have concerns about ventilation requirements. It’s imperative to know the location of eye wash stations, showers, and general first-aid kits. Familiarize your team with symptoms of chemical exposure and proper emergency response measures.

Thoroughly review the operation manual for your specific model of aqueous washer. Prioritize understanding safe loading limits, recommended wash cycle settings, and all scheduled maintenance tasks.

Never exceed the washer’s designed load capacity, as this leads to subpar cleaning, risks damage to both parts and internal components and shortens the machine’s overall lifespan.
Adhere to temperature ranges mandated for safe use. Excessive heat poses burn risks, and some chemistries lose effectiveness outside specified ranges. When in doubt about the compatibility of plastic, composite, or sensitive metal parts with your wash solution, always consult your solution provider.

Understanding and abiding by local and regional regulations governing wastewater disposal and spent cleaning solutions is paramount. These ordinances can vary significantly between locations, so it’s vital to research and educate yourself about requirements specific to your operations.

Consult with your Jenfab solution provider or reputable waste disposal service to help classify and analyze your waste materials. This process guides you in understanding safe disposal methods. In many cases, filtering your cleaning solution and using technologies like oil skimmers helps prolong the solution’s life.

This strategy not only improves cleaning results but directly leads to lower waste volumes and disposal costs.

Safety remains paramount in the design and operation of industrial cleaning equipment. Features such as fusible links in parts washers and automatic shut-off functions in submersible pumps are not just advancements; they are essential components that protect operators and environments alike.

From the engineering floors of manufacturing factories to the facilities of pharmaceutical companies, we ensure every device is equipped with these safety measures.

Comprehensive training is non-negotiable for everyone interacting with the parts washer. Proper safety protocols and operating procedures must be reinforced continuously.
