The Ascaso Steel DUO PID + i-Steel Bundle features the Ascaso Steel DUO PID espresso machine and the i-Steel coffee grinder.

This classic duo goes hand in hand with its Industrial/Modern design.



The STEEL range goes one step further and transcends the Home use. It is a semi-professional coffee machine for home, offices, and even the Hospitality channel.

DUO – a group for coffee and a group for steam.

It was designed by the Ascaso Factory engineering team in its UNO and DUO versions and it is offered in a robust industrial bodywork that meets the requirements of the expert user. It is manufactured with the highest quality materials (aluminum, stainless steel, brass), and a minimum use of plastic. The standard version is equipped with a Ø 58mm filter holder and electronic temperature control.

The PID version provides a completely professional performance: externally adjustable OPV and an external PID display for temperature setting, adjustable pre-infusion, stand-by option and much more. A professional machine at Home!

The Ascaso i-Steel coffee grinder is durable and offers the professional results that any barista would approve. Made of stainless steel and high quality components. The grinding burrs are made from special tempered steel, the same as used in professional high-performance coffee grinders. Small but robust, perfect for home or the office.

 Features and Functionality 

  • Manufactured in stainless steel for maximum sturdiness. The range is completed with 1, 2 or 3 groups. A wide range of possibilities that make this a truly professional machine in a domestic environment
  • The mobile filter holder model (ground coffee/versatile) includes a Tam-tamper: Professional aluminium coffee tamper (57 mm) designed by Marc Aranyó
  • Special cappuccino steam wand: Stainless steel. Multidirectional to 360º. The wand is cold to the touch, reducing the risk of contact burns. Milk build-up is reduced to a minimum, making for easy cleaning
  • Powerful steam/hot water: The new aluminium + stainless steel group guarantees continuous, unlimited steam. The life of the piece is now much longer thanks to the fact that lime scale does not build up on the stainless steel circuit
  • 2-litre water reservoir: Can be removed for easy maintenance, cleaning and visual access, allowing the user to quickly check the amount of water in the chamber. The reservoir can be filled with the coffee machine in operation. BPA – free
  • Cup warmer: Emulating professional coffee bar machines, the upper part features a surface that keeps cups warm, ensuring that coffee remains at its optimum temperature.
  • Stainless steel tray: Beauty and simplicity. A geometrical design that recalls the classic lines of bygone espresso machines. Easy to clean, with an extractable tray containing coffee spill
  • Metal switches: The high quality of the machine makes it a pleasure to use. Emphasizes the industrial look.
  • Lighting for work area 
  • Note: comes with a 20 amp plug to comply with Canadian Standards
  • Grinder burrs are made from special tempered steel used in professional, high performance grinders (service life is 600kg)
  • Micrometric adjustment allows maximum grind adjustment to any kind of coffee beans
  • Adjustment takes seconds for a perfect grind
  • Electronic timer
  • Body is made from stainless steel

Powerful Steam

New software: Instant, constant and powerful steam

Ascaso Steel DUO PID new update Steam

1. More steam power is gained by increasing the working surface of the steam circuit.
2. Extra steam pressure can be generated just by delaying the opening of the tap after activating the system.
3. Our new software algorithm has increased the power of steam in 25%!!

Steam Independent From the Boiler

  • Improves energy consumption. Reduced from 35% to 70%, according to EN60661 test.

  • Avoid heating element failures. Ascaso also offers a 5-year warranty on the steam unit that includes it.
    Vacuum valves, safety valves and immersion probes are also eliminated.

  • Waiting time for activation 2 minutes. Our steam unit is ready within 2 minutes after switching on. Once switched on, steam generation is instantaneous. A boiler takes between 15 and 25 minutes from start-up.

  • Instantaneous regeneration time. Constant steam. A boiler takes several minutes to recover if it has previously made steam, proportionally to its use. With our system the waiting time is zero. Throughout the process it does not lose steam, it is constant for 3 minutes (maximum established for system safety) and then recovers instantly.

  • Clean water in every steam service (no water constantly overheated).

Steam Control with PID

The electromechanical pressure switch is eliminated. Common in the industry, but not very precise and with mechanical failures.

Selection of the temperature of the coffee group by means of the display. From 110ºC to 165ºC

Steam Knob

Upgraded to a steam knob in place of the switch.

You don't have to wait a second to get steam. Simply activating the steam function allows us to open or close the tap to get steam instantly.

More professional approach to steam generation operation.
