How to Refurbish and Upgrade Auctioned Brewery Equipment

Introduction  

Buying used gear from a brewery equipment auction can feel like striking gold—or like stepping into a mess. It really depends on what you get and how prepared you are to deal with it. Some of this stuff has been sitting in storage for years. Some might have been heavily used in a production facility that shut down.

But here’s the thing: with the right approach, you can turn that dusty mash tun or fermenter into something production-worthy. Not perfect maybe, but solid—and often at a fraction of the cost of buying new.

1. Get a Clear Picture Before Doing Anything  

Don’t start scrubbing or tinkering right away. Take a good look at what you bought. Check for dents, corrosion, leaks, old seals, anything loose or missing.

If you’re not sure what to look for, it’s worth having someone experienced walk through it with you—even if that means calling in a favor or paying a tech for an hour or two. You'll save yourself from overcommitting to a piece that just isn’t worth the repair cost.

Also, ask: does this piece even fit your current brewing system? Can it handle your volume? Will it talk to your other equipment?

2. Clean It Like Your Beer Depends on It (Because It Does)  

Old tanks and gear are usually filthy. Like, seriously filthy. Grime, rust, and dried-up residue inside pipes and valves can mess up flavor, clog systems, or worse. Start with a deep clean. Not a quick wipe—take things apart if needed.

Use brewery-safe cleaners. Sanitize after you’ve cleaned. If you don’t trust it yet, run a test clean with hot water or a cleaning agent and see what comes out. Spoiler alert: it might be horrifying at first.

3. Replace What’s Cheap but Critical  

Gaskets, clamps, seals, hoses—those are usually cheap, and it’s better to replace them than risk a leak or contamination.

Don’t ignore gauges and sensors either. An inaccurate temp reading can ruin a whole batch. If you're unsure how old the electronics are, consider swapping in digital replacements.

Don’t overthink this part. Prioritize functionality over perfection. A new $20 part can keep a $5,000 tank running safely.

4. Make Smart Upgrades  

Now, you might not need to go all-in with automation, but a few basic upgrades can go a long way.

Adding a digital controller to manage temps

Installing a sight glass or flow meter

Improving insulation around fermenters

Setting up a basic CIP (clean-in-place) loop

It doesn’t have to be fancy—just useful. Look for upgrades that save you time or reduce waste.

5. Refinish for Durability and Looks  

After fixing and testing, think about the exterior. You don’t need showroom-level polish, but if it looks like it came out of a scrapyard, that’s not ideal—especially if customers or inspectors ever see your space.

Touch up with food-grade paint. Polish the steel if it’s badly stained. Replace broken indicator tags or safety stickers. Looks don’t brew beer—but they do matter, especially if you’re trying to grow or pitch investors.

6. Run a Dry Test (Then a Wet One)  

Once everything looks and works better, run a test. Start dry. Power up motors or pumps (without product) and listen. Any weird sounds? Vibrations? Smells?

Then do a wet test—just water or cleaning solution. Look for leaks, pressure inconsistencies, faulty valves. This is where hidden issues tend to show up. Better to deal with them now than during a real brew.

7. Document What You Did  

You might not think this part matters, but it will later.

Keep a folder—digital or paper—with:

• Part replacements and sources

• Calibration data (if applicable)

• Service records and maintenance logs

• Photos from before and after

It helps with resale later, keeps your crew aligned, and makes audits or inspections a lot less painful.

Final Thoughts  

Refurbishing auctioned brewery equipment isn’t always pretty, but it’s often worth it. You don’t need the latest high-end system to make great beer—what you do need is gear that works, runs safe, and supports your workflow. And with the right approach, that dusty fermenter you scored at a brewery equipment auction can end up being one of the smartest investments you make.
