Espresso machine „Ascaso“ Bar ONE, 1 group, Black

Single-group espresso machine with a thermoblock and a 4 L steam boiler

The „Ascaso“ Bar ONE is a professional single-group espresso machine with a Ø 58 mm portafilter. The coffee group is heated by an insulated thermoblock, while a separate 4 L stainless steel boiler supplies steam and hot water, so you brew espresso and froth milk at the same time.

A thermoblock combined with a separate steam boiler uses energy more efficiently than a traditional espresso machine. The machine draws water from a 5 L tank or straight from the mains — you choose the version when you order.

①

Thermoblock

The group heats up quickly and holds its heat: an insulated thermoblock heats it.

②

Stable temperature

Every espresso tastes the same: electronic control keeps the brew temperature within ±1.5 °C.

③

4 L steam boiler

You froth milk while the coffee is brewing: a separate insulated boiler supplies steam and hot water.

④

Volumetric control

Every cup gets the same shot: the machine measures its two programmable doses by volume, and a technician sets the pump pressure for your coffee with the over-pressure valve (OPV) on the group.

⑤

Ø 58 mm portafilter

Your barista works with professional tools: a Ø 58 mm portafilter, baskets and a shower screen, all in stainless steel.

⑥

Stainless steel

Built to last: the steam boiler, steam wand and drip tray grid are stainless steel.

⑦

Work area lighting

An LED light shines on the cups, so you can always see the coffee pouring.

⑧

5 L tank or mains

Choose a version with a 5 L tank that slides out from the side, or one that is plumbed into the mains.

⑨

Industrial design

Your bar looks modern: the industrial-style body combines black epoxy-coated steel with stainless steel.

Who it is for

The Bar ONE is made for baristas who brew espresso from freshly ground coffee. The whole machine is just 440 mm wide.

The right temperature for every cup

The brew temperature adjusts from 90 to 106 °C in 2 °C steps to suit your coffee.

The group is ready to brew about a minute after you switch on, so the first espresso is served almost straight away.

The same dose every time

Programme the small (S) and large (L) doses once, then just press the button and the shot stops automatically.

The XL button keeps the coffee flowing until you press it again — handy for an unusual cup size.

Espresso the way you like it

Make a single espresso with the 7 g basket and a double with the 14 g one.

Well-ground, well-tamped coffee runs for 20–25 seconds, so the shot time tells you when the grind is right.

Between shots the portafilter stays locked into the group, so it stays warm.

Milk foam and hot water

Steam is ready whenever you need it: a pressure switch keeps the boiler at 1–1.5 bar, and the gauge shows when it is up to pressure.

The Ø 12 mm stainless steel steam wand stays cool to the touch, so you can hold it safely; choose the 2-, 3- or 4-hole tip to suit the amount of milk you are frothing.

Hot water for tea or for warming cups comes from a separate outlet.

Easy every day

The level sensor tells you when it is time to refill the tank, and a plumbed-in machine draws water straight from the mains.

The main switch turns on the coffee group alone or together with the steam boiler, so the boiler runs when you need steam.

Cups up to 12 cm tall fit under the group, and the adjustable feet (±30 mm) let you level the machine on the counter.

Comparison

The Bar KAP and Bar ONE share the same thermoblocks, steam boiler and controls; the difference is how the coffee is made.

If staff without barista experience will be making the coffee, choose the „Ascaso“ Bar KAP, which makes espresso from FAP capsules.

Installation

• Power supply: 230 V, 50 Hz, 2,200 W; the circuit must be rated for at least 10 A.
• Tank: fill the 5 L tank with at least 3 L of fresh water and leave room at the side to slide it out; low-mineral water makes better-tasting coffee and helps the machine run trouble-free.
• Mains water: the plumbed-in version connects to a water tap with the supplied hose (3/4″ connection, 1–10 bar) and to a drain.
• Location: a flat, stable surface indoors at 0–40 °C; dimensions 440 × 540 × 450 mm (W × D × H), weight 35 kg.

Maintenance

Once a week, soak the portafilter and baskets in „Ascaso“ Coffee Washer solution, and backflush the group with the same cleaner using the supplied blind filter.

Wipe the steam wand with a damp cloth straight after use, and rinse it with steam wand cleaner at the end of the day.

Every three months, or every 3,000–6,000 coffees per group, a technician cleans and descales the internal circuit with „Ascaso“ Coffee Washer — the coffee keeps tasting great and the machine lasts longer.

What’s in the box

The machine comes with a double-spout stainless steel portafilter, single (7 g) and double (14 g) stainless steel baskets, a blind filter, an aluminium tamper, a measuring spoon and 2-, 3- and 4-hole steam tips. The plumbed-in version comes with water supply and drain hoses.
