Ascaso Steel DUO Plus PID Espresso Machine

by Ascaso

The Ascaso Steel DUO Plus is the latest model in the Ascaso Steel series. The main improvements over the regular DUO are:

  • Joystick steam valve
  • Competition shower screen
  • Bottomless portafilter
  • Wire stainless steel tray
  • Stainless steel tamper (instead of aluminum)

The Ascaso Steel Duo Plus PID offers a unique combination of style and technology amongst the double boiler machines.  The Duo Plus PID combines industrial styling with technologies to make it a unique and compelling option in the double boiler machine category.  With features like PID temperature control, 58mm professional portafilter, volumetric controls, externally adjustable over-pressure valve, brew pressure gauge, no burn steam wand and an two insulated thermoblocks; the Ascaso Steel DUO Plus PID will suit every home or small office setup. 


  • PID Temperature Control:  The PID (Proportional Integral Derivative) controller allows the user to precisely adjust the brew or steam temperature and improve temperature stability.  It also doubles as a shot timer while brewing.
  • Energy Efficient Thermoblocks:  The stainless steel and aluminum thermoblock combined with the PID controller results in exceptional temperature stability and fast warm up time.  On demand heat combined with insulation also makes the Steel Duo Plus PID very energy efficient.  The two thermoblocks mean that you can brew and steam for an efficient workflow.
  • Joystick Steam Valve: Easier to use and a more intuitive movement. Steam generation is also automatic. 
  • Competition Shower: AISI 304 stainless steel. Integrated membrane, completely smooth surface avoiding coffee residue deposits, which increases its useful life and facilitates cleaning.
  • Externally adjustable OPV: Brew at the pressure you want thanks to an externally adjustable over pressure valve (OPV).
  • Volumetric controls: Program 2 doses to a precise volume of water to improve repeatability.
  • 100% stainless steel water path: The entire water path is made of AISI 316 stainless steel to ensure no metal migration and reduce limescale build-up.
  • Wood Accents: Walnut wood knobs as well as a wood handle on the58mm commercial grade portafilter complete the look of the Steal Duo Plus PID.
