Ascaso Steel DUO PID Espresso Machine

by Ascaso

This is the newest model of the Ascaso Steel Duo PID that now includes the long requested steam valve knob as well as improved steam power!  

The Ascaso Steel Duo PID offers a unique combination of style and technology amongst the double boiler machines.  The Duo 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 PID will suit every home or small office setup. 

Note: The Ascaso Steal Duo PID requires a 20A circuit with a NEMA 5-20P plug



  • 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 PID very energy efficient.  The two thermoblocks mean that you can brew and steam for an efficient workflow.
  • 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 PID.
  • Professional tamper:   Comes standard with a 57mm steel tamper. A 58mm tamper does not fit in the OEM basket due to the shape, but the basket can be upgraded to a precision basket to accommodate 58./58.5mm tampers.

Alex G. (Baie-D'Urfe, QC)

Coming from more than a few years of using an E61 heat-exchanger machine - Ascaso's Steel PID line of machines feels like cheating. It's too easy and definitely less involved.

-Warmup time is quasi-instant (more so when compared to heat-exchangers)
-Drinks quality (too easy with the PID)
-Reaaaalllly nicely dampened pump noise
-Overall machine's looks and feel
-Honest 58mm, E61-specs group (no proprietary non-sense)

-Volumetric control seems to be upstream of the OPV - hence triggering of the latter screws up the net output volume.
-I don't particularly like the on/off nature of DUO's steam. Being used to machines with an actual turn-valve, I should have gone for the UNO. It's just so much easier to purge before and after steaming.
-One of the reasons for getting the DUO - was the fact that we're using our machine for a variety of drinks - not all requiring steaming. However - it seems that there's no explicit way to keep the steam thermoblock OFF unless it's disabled in PID. Again - it feels like UNO would have been a more honest choice for us.
-Availability of parts. Original Ascaso's naked portafilter is backordered everywhere with no ETA.

Overall, we're very happy with the purchase. Thx for making this happen Coffee Addicts!

PS This is of no Coffee Adddicts fault by any stretch, but if your machine is being shipped further than 2 provinces away from Alberta - please don't be expecting any miracles from UPS...
