Pre-Infusion & BrewLOGIC: Consistent Coffee Quality Every Time
The BUNN Axiom 15-3 uses a combination of pre-infusion and BrewLOGIC technology to ensure every batch tastes just right. Pre-infusion wets the coffee grounds before brewing, encouraging even extraction and more flavorful pots. BrewLOGIC helps adjust brew time if there are flow changes—great for areas with variable water pressure or heavy use.
Real-world example: If your water lines slow down during busy times, the machine compensates, so you always get a full pot and a balanced cup. This limits the risk of weak or burnt coffee during rush hours and helps even inexperienced users get reliable results.
Energy-Saver Mode & Cold Brew Lock-Out: Smarter Power and Safety
Leaving a commercial coffee maker on all day can add significantly to your energy bills. The BUNN Axiom 15-3’s energy-saver feature lowers tank temperature between brewing sessions, while the cold brew lock-out and automatic warmer time-out make sure your coffee isn’t sitting too long, losing quality or posing a safety hazard. These technologies give peace of mind for both managers and daily users.
Common question: “Will it waste power overnight?” The Axiom 15-3 does not have an on/off switch, but energy-saver mode helps mitigate idle energy use. For locations with strict power policies, consider using a timer or unplugging after hours.
SplashGard Funnel: Keeping Hands Safe from Burns
Busy mornings mean fast hands, and BUNN’s patented SplashGard funnel keeps hot coffee right where it belongs—away from your skin. By redirecting liquid back into the filter area, it reduces the chances of burns, which is especially important in staff rooms or kitchens where people may rush to get their caffeine fix.
Example: In school staff lounges, where users might not always be focused, this feature helps avoid accidents or costly downtime caused by spills.

- BrewLOGIC and pre-infusion for better, more consistent taste
- No power switch, which may matter for strict energy controls

Review Feedback Highlights
We purchased this brewer for our teacher’s lounge. It had been almost a full year since we’d had a Bunn coffee maker. Initially, we were renting one (with coffee, filters, etc.) from a beverage company to the tune of about $400.00 a month. Our principal decided that was crazy, and out the door it went. In came a plain old Mr. Coffee, and if you weren’t first to the pot in the morning, you were basically out of luck. It took forever to brew a pot, and with only one pot available, well, it just didn’t do the job.So, we decided to purchase one. This is an awesome machine. It hooks directly to the water, so you always have hot water – a must for our tea and hot chocolate drinkers. The display tells you how long it will take to brew a pot (around 3 minutes – plenty of time to brew and get a cup during a 5 minute passing period), and with Subscribe and Save, we will never run out of filters, sugar, creamer, or stir sicks.Now we have happy caffeinated teachers!The seller shipped quickly and the packaging was great!Happy teachers make for happy kids…mostly…until testing…
Through the years we have purchased at least a dozen Bunn coffee makers, burners, etc. This one has an interesting arrangement for the burners and it can handle three carafes at a time. Very good design!
Careful. This model has no power switch. So if you are closed, it will stay heated. Total waste of electricity.
