What Makes the Steel Duo Plus Different?

• Dual Thermoblock System – Brew espresso and steam milk simultaneously.
• Ready in About One Minute – Rapid heat-up for everyday convenience.
• PID Temperature Control – Precise brewing and steam temperature management.
• Programmable Pre-Infusion – Greater control over extraction quality.
• Volumetric Dosing – Two programmable shot volumes for consistency.

Built Around Workflow Speed

The primary advantage of the Steel Duo Plus is its dual thermoblock architecture. Unlike single-boiler machines that require users to switch between brewing and steaming modes, this machine maintains separate heating systems for coffee and steam.

The result is a smoother workflow, especially for milk-based drinks. Brew espresso while steaming milk simultaneously, reducing preparation time and creating a café-style experience at home.

• Independent Coffee & Steam Systems
• No Waiting Between Brewing & Steaming
• Rapid Warm-Up Performance
• Consistent Daily Operation

Precision Temperature Management

The integrated PID system allows users to adjust brewing temperatures from 80°C to 110°C and steam temperatures from 110°C to 165°C. This flexibility helps optimize extraction for different coffee origins, roast levels, and brewing preferences.

The insulated thermoblock design contributes to thermal stability while improving energy efficiency compared to traditional boiler systems.

• PID-Controlled Brew Temperature
• Independent Steam Temperature Adjustment
• Thermal Stability of ±1.5°C
• Digital Multifunction Display
• Real-Time Shot Timer

Designed for Espresso Enthusiasts

The Steel Duo Plus incorporates many features typically found on larger prosumer machines. Programmable pre-infusion, adjustable OPV pressure control, volumetric shot programming, and a professional 58mm filterholder provide the tools needed for precise espresso preparation.

Whether you're refining extraction variables or simply seeking repeatable results, the machine offers substantial control without becoming overly complicated.
