CREMINTERATIONAL Onyx PRO 2GR Espresso Machine

A professional espresso machine extracts flavour under controlled pressure and temperature, turning finely ground coffee into rich, aromatic shots. The Onyx PRO 2GR uses insulated brew groups heated by a PID system that holds water at a steady temperature throughout the brewing cycle. This consistency is essential for replicating the same taste profile in every cup, whether the machine is used for a single espresso or a busy service period.

The process begins with soft pre-infusion, where water gently saturates the coffee grounds before full pressure is applied. This gradual absorption allows the grounds to expand evenly, releasing natural oils and aromas without the bitterness that can come from sudden extraction. Once the pre-infusion is complete, the machine applies full pressure, forcing hot water through the puck to produce a balanced, full-bodied shot.

To operate the machine, the barista loads the portafilter with ground coffee, locks it into the brew group and selects the desired programme on the 2.5-inch LCD touchscreen. The screen responds to a single touch, activating the brew cycle, steam wand or cleaning function. Milk is heated using the automatic steam wand, which monitors temperature and shuts off when the set point is reached. The wand does not draw milk from a container, so the operator must manually position the jug under the nozzle.

The machine is built with a stainless-steel frame and insulated brew groups. Front and rear panels can be customised to match a café's branding, while LED lighting around the worktop can be set to any colour, making the machine a visual centrepiece. A quick-release cup rest adjusts to hold different cup sizes, keeping the worktop clear and organised.

The 3.33 kW power rating indicates the load the machine places on the electrical supply. In a professional kitchen, this requires a dedicated 230 V circuit to avoid tripping breakers during peak demand. The 70 kg weight means the unit is moved with a trolley or two people, and the 705 × 585 × 520 mm footprint determines the space it occupies on the counter or under a shelf.

The 11.5 L water tank supplies the brew groups, while two additional 1.5 L tanks are used for cleaning solutions. Automatic rinse cycles can be activated with a single button press, flushing all brew groups simultaneously. The steam wand and brew heads should be wiped after each use to prevent milk residue and coffee oils from hardening, and the drip tray emptied regularly to maintain hygiene.

The Onyx PRO 2GR is a two-group espresso machine designed for high-volume coffee service in cafés, restaurants and hotels.
