PID Temperature Control
The Ascaso Steel UNO Professional PID Espresso Machine outperforms other home equipment with its highly advanced PID temperature controller. A PID (short for Proportional, Integral, Derivative) is essentially a computerized, digital thermostat that uses a lot of math to accurately maintain the boiler temperature to your desired level. Simply use the up or down arrows and the digital display to select your desired temperature and the Ascaso Steel PID does the rest. Many espresso enthusiasts have taken to modifying their home and commercial espresso machines to install PID controllers, but this Ascaso Steel UNO comes with the unit pre-installed and tuned to this boiler size and heating element.
Professional Power Brass Boiler
Ascaso engineers designed the Steel UNO Professional PID's boiler to supply ample amounts of hot water and steam for all your espresso and milk frothing needs. Not only does the 11 ounce capacity grant you considerable temperature stability, but the 1200 Watt heating element also gets the Steel up to temp more quickly than any other machine with such a large boiler. Ascaso also included a low water shut-off, a very life-saving device normally found only on heat exchanger espresso machines. In addition, the all-brass is situated directly above the brass brew group to minimize heat loss. It's just one of the many ways that Ascaso sets itself above the rest of the competition.
Commercial Size Portafilter And Filter Baskets
Just like a commercial espresso machine, the Ascaso Steel UNO Professional PID uses only heavy-duty chrome plated brass portafilter holders and spouts. Unlike many home espresso machines, however, the Steel UNO PID is equipped wtih true 58 mm filter baskets for not only conformity to the commercial standard, but also to make it easy to find a quality tamper that suits your taste. The same filter holder is used for both ground coffee and pods, and the Ascaso Steel UNO PID comes with 3 stainless steel filter baskets for different espresso preparations. Included are separate single shot and double shot 58 mm diameter filter baskets for ground coffee.
Easy Froth Steam Wand
The stainless steel steam wand on the Ascaso Steel PID makes it easy to create that velvety micro-foam that we have all come to love. Frothing milk on a commercial machine is hard enough, so Ascaso designed this swivel-mounted steam wand with a special aeration hole drilled on the side of the frothing tip. When frothing milk on the Ascaso Steel, please make sure to have the little hole in the frothing adapter positioned at the top level of the milk. Doing it this way will help force more air into the milk to make the process easier.
3-Way Solenoid Valve
The Ascaso Steel UNO Professional PID is one of the few home espresso machines under $700 to be equipped with a 3-Way Solenoid Valve. This valve, a critical component on commercial espresso machines, is located on the group body. It not only directs the flow of water from the boiler to the brew group, but it also acts to relieve remaining pressure once the brew cycle is complete. This process stops the dripping after you are done brewing your espresso, and it also dries out the coffee puck so that it may be knocked out more easily.
Easy To Use Controls
The Ascaso Steel's 3 metal switches and steam knob give you entire control over the brewing and steaming process. Each of the push button switches put other brands' controls to shame; these ones are built to last. The center switch turns the Ascaso Steel UNO PID on and off, while the left-most switch heats the boiler to steam temp, and the right-most switch starts and stops the espresso brewing process. Indicator LEDs just beneath each switch inform you when the Steel is powered up, and when it is at the proper temperature for either brewing espresso or frothing milk, and a third LED illuminates when the water level is low.
Commercial Quality Brew Group
Designed after Ascaso's commercial espresso machines, the Steel UNO PID group head (the part that accepts the portafilter) evenly distributes heat and reduces "hotspots" for more temperature consistent espresso. The marine grade brass is chrome plated for corrosion resistance and easy cleanup. It has also been designed to evenly distribute water across the coffee grounds for a better extraction.
Removable Water Tank
The Ascaso Steel UNO PID uses a 68 ounce removable water reservoir, equipped with a low water cut-off, that can be filled while operating or can be taken out and filled at the faucet. In addition, one of the blue LED indicators will illuminate when the water level is too low.
