ARI 700 and the non-glamorous, essential truth about reclaimed refrigerants

Let me ask you a simple question: when a used refrigerant changes hands, what guarantees it’s going to work without mistreating equipment or spewing trouble into the air? The answer isn’t “more bottles” or “fewer leaks.” It’s purity. In the world of refrigeration, nothing fuels reliable cooling like clean refrigerant. That’s where ARI 700 comes in. This standard, maintained by the industry’s trusted bodies, sets the bar for what reclaimed refrigerants must look like before they’re sold again. Think of ARI 700 as the cleanliness screen door that keeps dirty contaminants out of your systems.

What ARI 700 is all about

ARI 700, short for the specifications for refrigerants that are recovered, reclaimed, and prepared for resale, is a purity-focused guideline. It defines acceptable impurity levels, test methods, labeling, and the documentation that backs up those claims. In plain terms: if a batch of refrigerant is going to be resold, it has to prove it meets certain purity standards. The standard isn’t about how you store or handle refrigerants day to day (though those practices matter); it’s about guaranteeing the chemical composition is clean enough to be safely used again.

Why the phrase “must meet ARI 700 standards” matters to you

When a supplier shouts that a batch “meets ARI 700,” they’re saying: this refrigerant has passed a set of checks designed to catch common troublemakers — moisture, acidity, non-refrigerant contaminants, and certain trace impurities. Contaminants aren’t just academic concerns. They can cause lubrication problems, corrosion, formation of acids, degraded performance, and even safety hazards such as unexpected pressure changes. In short, ARI 700 compliance translates into predictable performance, reduced system risk, and fewer callbacks.

But what exactly does not meet ARI 700 look like? It’s not a matter of color indicators, pressure limits, or shiny new containers alone. Those are important pieces of handling and storage, but ARI 700’s core focus is purity and traceability. You can store refrigerants correctly, label them properly, and yet if the batch doesn’t meet purity specifications, it isn’t ready for resale. The standard ensures you’re not buying or selling a mixed bag of recycled chemicals that could compromise a compressor, a coil, or a whole cooling loop.

Why purity matters for equipment, safety, and the environment

Here’s the practical line: impure refrigerants can cause early wear on seals and lubricants, promote corrosion, and create residues that reduce heat transfer efficiency. When you’re charging a system, you want to be confident that the refrigerant will perform as designed. Contaminants can also complicate recovery and recycling efforts. From an environmental perspective, reclaimed refrigerants that don’t meet purity criteria run a higher risk of venting or releasing harmful substances during handling. That’s not just bad for the planet; it’s bad for the shop’s reputation and the technician’s credentials too.

How reclamation works in the real world

Reclaimers operate a multi-step process to bring used refrigerants up to ARI 700. The journey typically starts with capture and separation of oil from the refrigerant. Then comes dehydration to remove moisture, followed by polishing to reduce acidity and remove non-volatile contaminants. Some facilities employ distillation to separate components and further refine the batch, and rigorous final testing ensures the product meets the required purity levels.

A lot of the heavy lifting happens behind the scenes in certified facilities. The tests aren’t whimsical — they’re standardized checks designed to quantify impurities and to verify that the final product matches the purity profile expected by ARI 700. The labeling you see on ARI 700-compliant reclaimed refrigerant isn’t just a sticker; it’s a signal that the batch has passed a defined slate of tests and is suitable for resale into refrigeration and air conditioning systems.

What to verify when you’re sourcing reclaimed refrigerant

If you’re in a role where you select reclaimed refrigerant for a project, here are a few practical steps to keep things clean and compliant:

• Look for ARI 700 compliance on the product label. This is your first check.

• Ask for documentation. Reclaimer certifications or lab reports that show test results against ARI 700 criteria can save you headaches later.

• Verify the reclaimer is reputable. Reputable reclaimers follow process controls, keep meticulous records, and participate in regular third-party testing.

• Understand the batch specifics. Some products may be ARI 700 compliant in general, but you’ll want the lot number and date to confirm it meets the standard at the time of sale.

• Don’t ignore storage and handling in the store or shop. Even compliant refrigerant needs proper containers and clear labeling to stay clean until it’s installed.

A note on the other moving parts in the field

You’ll hear comments about pressure limits, color-indicator containers, or rapid re-packaging. Those elements matter for day-to-day handling and for certain regulatory contexts, but ARI 700’s core demand is purity for resale. It’s entirely possible to have a batch that is correctly stored and labeled, yet still not meet ARI 700 because the composition isn’t clean enough. That’s a reminder: the standard isn’t a cosmetic requirement; it’s a performance and safety benchmark.

The practical tasks technicians often encounter

• Inspect incoming reclaimed refrigerant for ARI 700 compliance before it’s used in another system.

• Track and preserve the provenance of the refrigerant. Records matter if there’s a future question about purity or contamination.

• Coordinate with the supplier. If you notice odd side effects in a system, ask whether the batch was ARI 700-compliant and whether retesting is warranted.

• Maintain a clean workflow. From recovery to small-batch testing, every step should be documented. Documentation isn’t bureaucratic fluff; it’s traceability that protects you and your customers.

A quick, friendly checklist for staying compliant

• Confirm ARI 700 status on the label and in the accompanying paperwork.

• Request or review third-party test results and the lot number.

• Keep a clear record of where the refrigerant came from and where it’s going.

• Work with a trusted reclaimer who demonstrates solid process controls and regular testing.

• Store reclaimed refrigerant in appropriate, clearly labeled containers and in a location protected from heat and moisture.

Beyond the bottle: safety, environment, and everyday practice

Purity isn’t only a matter of keeping systems happy; it’s a safety and environmental concern. Contaminants can produce acids during operation, which attack metal parts and create leaks. They can also lead to improper lubrication, accelerating wear and shortening a system’s life. From an environmental perspective, ensuring that reclaimed refrigerant is clean reduces the risk of releasing harmful substances during disposal or reuse. The payoff isn’t merely compliance for compliance’s sake; it’s better performance, safer work environments, and a smaller footprint.

Where to turn for reliable information

If you want to dig deeper, the AHRI/ARI resources are the go-to places for official ARI 700 guidance and updates. EPA regulations around refrigerants, technician responsibilities under the EPA 608 program, and the broader context of refrigerant handling are worth reviewing too. Reading up on the practical implications of purity standards helps you connect the dots between theory and everyday job tasks.

Bringing it all together

Purity standards like ARI 700 aren’t glamorous in the way that the latest tech feature is, but they’re the quiet backbone of responsible refrigeration work. When you see that a batch of reclaimed refrigerant “meets ARI 700 standards,” you’re seeing a promise: a batch that’s been tested, refined, and prepared to perform reliably in a real system. That reliability translates into fewer service calls, happier customers, and safer workplaces. It also means you’re playing your part in a system that respects the equipment, the people who rely on it, and the environment.

If you’re curious to learn more about ARI 700 and how it fits into the broader landscape of refrigerant handling, you’ll find that the most useful knowledge isn’t just a checklist. It’s a mindset: treat reclaimed refrigerant as a commodity that deserves respect, because purity isn’t optional — it’s essential. And when you’ve got that mindset on the job, you’ll see the difference in every installation, every service call, and every satisfied customer.
