Solvent vs Aqueous Degreasing

In modern manufacturing and processing environments, the cleanliness of a component directly affects:

• Product quality
• Coating adhesion
• Assembly performance
• Equipment lifespan
• Compliance standards

What has changed over the last decade is not just the importance of cleaning—but the pressure surrounding it.

The Transition Away from Solvent Degreasing Systems

For decades, solvent degreasing was considered the benchmark for industrial cleaning. Its ability to dissolve oils and contaminants made it highly effective across a range of applications.

However, the environment around solvent cleaning has changed significantly.

The combination of:

• Rising chemical costs
• Increasing disposal requirements
• Tightening environmental regulations
• Greater focus on workplace safety

has made solvent systems progressively more difficult to justify in many industrial settings.

At the same time, aqueous degreasing technology has evolved. What was once seen as a lower-performance alternative is now a fully engineered process capable of handling demanding applications at scale.

Rotajet has seen a clear increase in demand from companies actively replacing solvent systems—not because they want to, but because operational and regulatory pressures leave little alternative.

Choosing the Right Commercial Approach: Buy • Rent • Contract

Once the technical direction is clear, the next decision is how the system is implemented commercially. This has a direct impact on cash flow, risk, and project speed.

Rotajet typically supports three structured approaches, each aligned to different operational needs.

Buying a System — Long-Term Control

Purchasing a system is the preferred route for businesses where degreasing is a permanent part of production.

Owning equipment such as the Rotajet D60 Industrial Parts Washer, Rotajet D80 Industrial Parts Washer, or Rotajet D108 Industrial Parts Washer allows full integration into the production environment.

This approach is typically chosen where:

• Throughput is consistent or growing
• Cleaning is business-critical
• Long-term operating cost reduction is a priority

Ownership also allows systems to be engineered fully around the site layout, utilities, and workflow.

Rental — Speed and Flexibility

Rental is increasingly being used as a strategic option rather than a temporary one.

It allows businesses to:

• Implement a system quickly
• Avoid upfront capital expenditure
• Validate performance under real production conditions
• Scale operations without long-term commitment

This is particularly useful when replacing solvent systems, where businesses want to confirm performance and cost savings before committing to a full capital purchase.

Contract Degreasing Solutions

For some operations, the priority is not ownership, but performance and predictability.

A contract solution allows Rotajet to supply and support the system while the customer focuses on production.

This model provides:

• Fixed, predictable costs
• Ongoing support and maintenance
• Performance assurance
• Reduced internal resource requirement

It is particularly suited to high-volume or multi-site operations where consistency is critical.

Specifying the Right System

Selecting the correct degreasing system is not about choosing a machine—it is about defining the process requirements.

The most successful projects begin with a clear understanding of:

• Type and level of contamination
• Required cleanliness standard
• Throughput targets
• Component size and geometry
• Available utilities (power, water, air)
• Space and layout constraints

From this, the system can be designed to deliver consistent performance.
