Quick Mill Rubino Plus Espresso Machine - HX Boiler Technology and PID Control

Compact machine offering precision temperature control

Tailor-made for coffee enthusiasts who seek maximum control in a compact form, the Rubino Plus Espresso Machine strikes the perfect balance between size and performance. Though modest in footprint, it features a highly efficient PID system for precise electronic management of water temperature within its stainless-steel insulated heat exchanger (HX) boiler. This ensures stability and consistency shot after shot, offering barista-level control from the comfort of your own kitchen.

OLED display and gauges ensure brewing accuracy

An intuitive OLED display makes adjusting settings effortless, including pre-infusion, stand-by mode, eco-mode, and extraction time monitoring. The distinctive double pressure gauge provides real-time feedback on both boiler and pump pressure, allowing for exceptional precision with every espresso. With the Rubino Plus Coffee Machine, the pursuit of coffee excellence becomes an everyday experience, refined, controlled, and always within reach.

We are pleased to introduce Instant Stability, a new machine variant available on existing Quick Mill models, including the Rubino+, Aquila, and Elevate V & R. This advanced technology integrates an active heating element directly into the brew group, managed by a dedicated PID for precise temperature control. With this system, the machine is ready to brew in just 12 minutes, ensuring exceptional temperature stability from the very first shot to the last. This innovation continuously compensates for thermal fluctuations during extraction, maintaining the ideal temperature range for consistent, high-performance quality every time.

Why Instant Stability Matters

• Fast, Controlled Heat-Up Thanks to active group control, the machine reaches its ideal extraction temperature much faster, significantly reducing waiting times. Starting from room temperature, the machine is ready in just 12 minutes:

  • With Instant Stability: 87.6°C

  • Without active heating: 62.3°C

  • This represents a 25.3°C difference, or a 40.6% increase in heating efficiency.

• Stable Shot After Shot Instant Stability ensures temperature consistency from the very first shot to the last. It maintains a steady thermal window in two key moments:

  1. Between shots, even with short intervals.

  2. Throughout each extraction, from the first second to the 30-second mark.

• Tested and Proven Performance Thermal stability has been verified through rigorous internal testing (10 consecutive shots at 1-minute intervals). The results show that Instant Stability reduces thermal variations by 41%:

  • With Instant Stability: Average ΔT of only 0.29°C (the difference between 15 and 30 seconds of extraction).

  • Without active heating: Noticeably higher fluctuations.

Consistent Results, Every Time

With Instant Stability, Quick Mill takes brew group temperature control to the next level. By continuously compensating for thermal fluctuations during both heating and extraction, the system ensures that the temperature you set is the temperature you get in the cup. This is a technology designed for those who seek high performance, precise regulation, and quality that stays consistent shot after shot.
