The grouphead (the part that accepts the portafilter) of the Uno Professional evenly distributes heat and reduces 'hotspots ' for more temperature consistent espresso. It has also been designed to evenly distribute water across the coffee grounds for better extraction. The marine grade brass is chrome plated for corrosion resistance and easy cleanup.
Its high quality means it can reach working temperatures quickly and in succession. Two thermostats control the temperature of the coffee and steam and a resettable thermostat protects the machine from accidental overheating. High capacity. Oversized to guarantee professional thermal stability and provide quality in every cup. The water circulates through an Inox circuit, reducing lime scale build-up to a minimum. Provides a limitless supply of steam.
PID Temperature Control
The control panel/digital display on the front of the machine is your access point to the built-in PID (Proportional, Integral, Derivative) controller which allows you program the temperature of the coffee boiler. Coffee experts know that some espresso blends brew better at 201 degree F and some at 196 degree F. Using a whole host of math equations, the PID maintains boiler temperature with exacting precision.
- Adjustable in one-degree increments.
- Electronic steam control.
- Stand-by option available.
- Coffee dose timer.
- Programmable pre-infusion. (0 to 5 seconds).
- Alarms (5): Water/coffee ratio, coffee or steam gauge, coffee group or steam. (Display indicates error type).
3-Way Solenoid Valve
The three-way solenoid valve is a commercial feature that relieves the water pressure off the coffee when the brew switch is turned off. The valve dries out the used ground coffee in the portafilter immediately after the brewing is finished. So you can straight away remove the handle, easily knock the dried coffee out and reset of the machine for another shot. The Steel Uno also features an adjustable over pressure valve that can be adjusted from 8 to 15 bars.
The Ascaso UNO Professional V4 boasts a powerful vibratory pump rated at 20 BAR of pressure to extract maximum flavor from the coffee beans.
No Burn Steam Wand
A multi-directional steam wand has an excellent range of motion for ease of use. It creates fine and creamy milk foam effortlessly for your cappuccino and latte. Hot water wand is also on a ball joint making it easy to pour water into a cup.
Easy to Use Controls
The grouphead is controlled by a simple push button that activates the vibration pump and opens the group solenoid valve to deliver coffee. Once the desired quantity is reached, press the push-button again to stop brewing.
The Uno Professional uses heavy-duty chrome plated brass portafilter holders and spouts. The machine comes equipped with commercial grade 58 mm filter baskets to make it easier to find a quality tamper that suits your taste. You can use the same filter holder for both ground coffee and pods. The Ascaso Steel Uno Professional includes 3 stainless steel filter baskets- separate single shot and double shot filter baskets for ground coffee and one single pod filter basket for ESE (Easy Serving Espresso) pre-packaged pods.
The new porafilter handle has a wood finish and it is tilted 10 degrees for easy use. If you place the portafilter on flat surface it is perfectly level making tamping a breeze.
The 68 ounce water tank is removable from the right side of the machine. You may refill the water tank any time during the operation or remove the tank to refill at your tap. In addition, one of the blue LED indicators will notify you when the water level is low.
Removable Drip Tray
You can easily slide out the plastic drip tray for easy cleaning. Front portion of pull out drip tray is in brushed black stainless steel.
