Overview
Dual-thermoblock speed. Precision espresso control. Built for the serious home barista.
The Ascaso Steel DUO V3 PID Espresso Machine brings a faster, more capable espresso workflow home with independent heating systems for brewing and steaming.
Its dual thermoblock architecture allows you to brew and steam simultaneously—a major advantage when preparing cappuccinos, lattes, flat whites, or multiple drinks back-to-back.
PID temperature adjustment, programmable pre-infusion, volumetric dosing, adjustable OPV, analog pressure gauge, and a professional 58mm portafilter provide meaningful control over extraction.
Add a 67 oz reservoir, approximately 3:30 brew warm-up, and walnut accents, and the Steel DUO delivers speed and control without the footprint of a large traditional boiler machine.
Key Features
- Dual Thermoblocks — Independent heating circuits for espresso and steam.

- Programmable Pre-Infusion — Customize the opening stage of extraction.
- Volumetric Dosing — Program single and double shot volumes.
- Adjustable OPV — Provides additional control over brewing pressure.
- Analog Pressure Gauge — Monitor pressure during extraction.
- 58mm Portafilter — Professional-size platform with walnut handle.
- Walnut Steam Knob — Traditional hands-on steam control.
- No-Burn Steam Wand — Designed for comfortable milk texturing.
- 67 oz Reservoir — Generous capacity without direct plumbing.
- AISI 316 Stainless-Steel Water Circuit
- Cup Warmer + Auto Shutoff
- E.S.E. Pod Compatible
Why This Product Stands Out
The Steel DUO's defining advantage is straightforward:
BREW + STEAM AT THE SAME TIME
Unlike a single-heating machine that generally handles brewing and steaming sequentially, independent thermoblocks allow both functions to operate simultaneously for a more efficient milk-drink workflow.
It also provides control over key espresso variables:
TEMPERATURE → PRE-INFUSION → PRESSURE → DOSE
PID adjustment, programmable pre-infusion, adjustable OPV, pressure monitoring, and volumetric dosing give developing home baristas room to refine their technique.
