Nu-Calgon Rx11-Flush Starter Kit for a Cleaner HVAC System

Keeping refrigeration and air conditioning systems free of contaminants is crucial for their performance and longevity. The Nu-Calgon 4300-08 Rx11-Flush Starter Kit provides a complete solution for technicians and knowledgeable DIYers to effectively clean out harmful residues from HVAC systems, especially during repairs or refrigerant conversions.

What is Rx11-Flush and What Does It Do?

Rx11-Flush is a specially engineered solvent designed to clean the internal lines and components of HVAC systems thoroughly. Its patented HFC-based solvent formulation is powerful enough to flush away common contaminants such as sludge, carbon residue, oils, acids, water, and other unwanted particles. Importantly, Rx11-Flush is non-toxic and non-flammable and does not deplete the ozone layer, making it a responsible choice for system cleaning.

When to Use an Rx11-Flush Kit

This flushing solvent is ideal for several critical situations. It's beneficial for cleaning a system after a compressor burnout, an event that can spread significant debris throughout the lines. Rx11-Flush is also essential when retrofitting an older system to a new type of refrigerant or for thoroughly flushing line sets when converting a system to use R-410A refrigerant. Removing old oils and contaminants ensures the new compressor and refrigerant can operate efficiently and reliably.

What's Included in the Starter Kit?

The Nu-Calgon 4300-08 Rx11-Flush Starter Kit comes with the essential components to get you started on a flushing job:

• One 1 lb. canister of Rx11-Flush solvent
• A durable spray gun for application
• A flexible hose
• An injection valve/tool for precise delivery into the system

This kit provides a convenient package for effectively introducing the solvent into the system lines.

Individual Canisters Also Available

If you already have the application tools or simply need more Rx11-Flush solvent for larger jobs or future use, Budget Air Supply also offers the canisters individually. You can purchase:

• Rx11-Flush 1-lb. Canister (4300-09)
• Flushes 1–2 line sets
• Rx11-Flush 2-lb. Canister (4300-11)
• Flushes up to 5 line sets

Both options provide the same reliable, high-powered cleaning performance in convenient refill sizes.
