Di Pacci — Commercial Rapid Cold Brew Machine
Baby Hardtank Cold Brew Machine
The Baby Hardtank makes a batch of cold brew in under an hour instead of overnight, on a bench space of 340 × 340 mm.
The Baby Hardtank is a commercial cold brew machine for cafés, drive-thrus, quick-service restaurants and bars. It brews 4 litres of cold brew per batch in under an hour, up to 30+ litres a day, with coffee extracting in 20–45 minutes. It runs on a standard power outlet (100–240 V) and draws just 60 watts.
Traditional immersion cold brew ties up containers for 12–24 hours and has to be planned a day ahead. The Hardtank recirculates water through a closed stainless chamber, so you can brew to demand during the day, run out less often and try new recipes without waiting until tomorrow to taste them. It also brews tea, cascara and spirit infusions, which turns one machine into a whole cold drinks menu.

Key Features of the Baby Hardtank
⚡ Cold Brew in Under an Hour
Brew to demand during service instead of guessing tomorrow's volume the night before.
🔄 Patented Dynamic Recirculation
Water circulates through the coffee in a closed chamber, which is what cuts extraction from a day to under 45 minutes.
♻️ Reusable Stainless Filter
No paper filters to stock, buy or throw out, and nothing to run short of mid-shift.
📱 Touchscreen Recipes
Save each drink as a recipe so every staff member brews it the same way.
🍸 Beyond Coffee
Brew tea, cascara, fruit and botanical infusions, or infuse spirits up to 60% ABV for a cocktail list.
🧼 Wash & Sanitise Programs
Built-in cleaning cycles with automatic drainage make daily cleaning a button press.
Why Rapid Cold Brew Changes Your Menu
Most cafés make cold brew in big immersion tubs that steep for 12–24 hours. That means committing to tomorrow's volume today, losing bench and fridge space to containers, and throwing away what doesn't sell. The Baby Hardtank turns cold brew into something you make as you need it.
- Fill the basket with up to 350g of ground coffee, pick a saved recipe on the touchscreen and start the cycle
- The machine recirculates water through the grounds in a sealed stainless chamber, extracting coffee in 20–45 minutes
- The built-in pump drains the finished cold brew to your keg. Run the 5-minute wash and start the next batch, up to 30+ litres a day
The payoff is less waste, fresher cold brew and the freedom to add new drinks. A seasonal tea, a fruit infusion or a cold brew cocktail can go from idea to tasting in under an hour.

Di Pacci recommendation: If cold brew is a steady seller, or you want to build a cold drinks menu around it, the Baby Hardtank pays for itself in time, waste and bench space. If you sell a few cold brews a week, don't bother: a simple immersion setup will do the job for a fraction of the cost.
What to Pair It With
Great cold brew starts with fresh beans and a consistent coarse grind:

Who This Machine Is For
✓ Ideal if you:
- Sell cold brew every day and want to stop prepping it the night before
- Run a café, drive-thru, QSR or bar with limited bench and fridge space
- Want to add tea, cascara or cold brew cocktails to your menu
- Need every staff member to make each drink the same way
- Want to cut filter waste and cleaning time
✗ Consider alternatives if you:
- Sell only a handful of cold brews a week
- Have no filtered water connection (0.2–0.4 MPa) and drain where it will sit
- Need more than about 30 litres a day from one unit
- Are after a hot espresso machine. See our commercial coffee machines.
Baby Hardtank — Frequently Asked Questions
How fast does the Baby Hardtank make cold brew?
Coffee extracts in about 20–45 minutes and tea in 15–30 minutes, depending on the recipe. Each coffee batch makes 4 litres, and the machine is rated for 30–32 litres a day, compared with 12–24 hours for traditional steeping.
What power and water connection does it need?
It runs on a standard power outlet (100–240 V) and draws a maximum of 60 watts, so no dedicated circuit is needed. It connects to a filtered or reverse osmosis water supply at 0.2–0.4 MPa through a 3/8" inlet, with a 1/2" drain, and should be installed by a qualified technician.
Does it use paper filters?
No. It brews through a stainless steel filter basket in a closed chamber, so there are no disposable filters to buy or throw away.
Can it make more than coffee?
Yes. It brews tea, cascara and botanical infusions, and can infuse spirits up to 60% ABV for cocktail menus. Saved recipes on the touchscreen let staff repeat each drink exactly.
How do you clean it?
The touchscreen runs a 5-minute wash and a 30-minute sanitise program, each using about 12 litres of water, with automatic drainage. Daily cleaning is a button press rather than a strip-down.
What warranty does it come with?
12 months parts and labour on a return-to-base basis. Contact us for service, parts or help with setup.
