Ascaso  ·  Dual Thermoblock Espresso Machine

The Ascaso Steel DUO PLUS

Brew and steam. At the same time. Every time.

The Ascaso Steel DUO PLUS is a dual thermoblock semi-automatic built for serious home baristas who want cafe workflow without the wait. Two independent thermoblocks, one for brewing and one for steam, enable simultaneous brewing and steaming with no temperature switching and no recovery time. A dual PID system controls both circuits independently to one-degree precision.

A competition shower screen, walnut joystick steam lever, externally adjustable OPV, analog pressure gauge, hot water tap, and volumetric programmable dosing round out a feature set that competes directly with machines at a significantly higher price. Brew-ready in under three minutes, fully stabilized in ten. Handcrafted in Barcelona, 25-point quality inspected, backed by a 5-year thermoblock warranty.

What Sets the DUO PLUS Apart

  • 01
    Dual Independent Thermoblock System
    One thermoblock is dedicated to brewing, one to steam. Both run simultaneously with no temperature switching. Insulated for thermal stability and approximately 50% more energy efficient than traditional boiler machines.
  • 02
    Dual PID Temperature Control
    Independent PID controllers govern both the brew and steam circuits with one-degree adjustment increments. What you dial in on Monday is what you get on Friday.
  • 03
    Competition Shower Screen
    AISI 304 stainless steel screen with an integrated membrane for a completely smooth surface. Prevents coffee residue deposits, resists buildup, and ensures even water distribution across the entire puck surface for consistent extraction.
  • 04
    Walnut Joystick Steam Lever
    Replaces the traditional rotary knob with an intuitive joystick for more directional control during frothing. Real walnut construction matches the portafilter handles. Steam generation is automatic on activation.
  • 05
    Externally Adjustable OPV
    Set your brewing pressure without tools or disassembly. Combined with the analog pressure gauge, you have full visual confirmation of where pressure sits on every shot. A practical, repeatable adjustment rather than a one-time setup step.
  • 06
    Volumetric Dosing with Pre-Infusion
    Program pre-infusion, single shot, double shot, and auto-standby volumes once and the machine reproduces them exactly. Pre-infusion saturates the puck evenly before full pressure, reducing channeling and improving extraction consistency.
  • 07
    No-Burn Steam Wand with Two Tips
    Insulated exterior prevents burns during fast-moving routines. Continuous, consistent steam power. Includes a single-hole and three-hole tip for flexibility across milk textures and drink volumes.
  • 08
    Hot Water Tap
    Stainless steel hot water tap dispenses at precise temperature for Americanos, tea, and cup preheating without a separate kettle.
  • 09
    100% Food-Safe AISI 316 Stainless Water Path
    No metal migration. Resists limescale buildup, the primary cause of long-term performance degradation. Fresh water is drawn for every shot rather than recycled from a standing reservoir.
  • 10
    Handcrafted in Barcelona, 25-Point Inspection
    Every DUO PLUS is handcrafted with premium materials and passes a rigorous 25-point quality inspection before leaving the factory. Built from powder-coated carbon steel and polished stainless steel.

Frequently Asked Questions

Can the DUO PLUS brew and steam at the same time?

Yes. Two independent thermoblocks run separate circuits for brewing and steaming with no temperature switching, no recovery time, and no sequential process. You pull the shot and steam the milk simultaneously.

How quickly does it heat up?

Brew-ready in under three minutes, fully stabilized in approximately ten. Among the fastest heat-up times in its class.

What is the difference between the DUO and the DUO PLUS?

The PLUS adds the walnut joystick steam lever, competition shower screen, wire grid drip tray, hot water tap, two steam tips, a food-grade silicone portafilter gasket, a bottomless portafilter, and enhanced PID stability. The core dual thermoblock architecture is shared between both.

What does the externally adjustable OPV do?

It controls the maximum extraction pressure without tools or disassembly. Combined with the analog pressure gauge, you have both the control and the visibility to make precise, repeatable adjustments shot to shot.

Does it require a dedicated circuit?

Yes. The DUO PLUS requires a 20-amp circuit (NEMA 5-20). A plug adaptor is included. Confirm your outlet configuration before purchasing if steam power is your priority.

How do I maintain it long-term?

Daily: wipe the shower screen, purge and wipe the steam wand, empty the drip tray. Weekly: backflush with a detergent tablet and clean the shower screen and gasket. Descale frequency depends on water hardness — Ascaso recommends 75-150 ppm and suggests filtration for harder water.
