Product description
Professional espresso machine with variable pressureControl the pressure curve as you dial in your shot
Stand in front of the machine and lock the portafilter into the 58 mm group head, then slowly pull the lever to raise the pressure from three to nine bar and lower it at the end, while two stainless steel boilers with capacities of 1.9 and 3.6 liters maintain a steady temperature. A professional espresso machine with a hydraulic system gives you complete flexibility to adjust the extraction curve to suit the coffee.
Three pillars of advanced extraction
Variable hydraulic system
Raise the lever to gradually increase the pressure, then lower it according to the extraction stage to unlock flavors a fixed-pressure pump cannot reach.
Dual PID-controlled boilers
A 1.9-liter brew boiler and a 3.6-liter steam boiler, each with independent temperature control.
Commercial rotary pump
A quiet pump delivers consistent pressure and works with a 2.5-liter tank or direct plumbing.
Extraction steps
Preparation
Grind the beans and distribute the grounds in the basket, then tamp and lock in the portafilter.
Increasing the pressure
Slowly raise the lever to increase the pressure from three to nine bar.
Adjusting the curve

Before you order
What does hydraulic pressure-curve control mean?
You can manually raise and lower the pressure during extraction, instead of keeping it constant throughout the shot, giving you control over the flavor based on the coffee.
Does it require a direct water connection?
No, it operates with a 2.5-liter internal water tank, with direct plumbing available as an option.
Is it suitable for beginners looking for a professional espresso machine?
No, it requires prior experience with extraction and pressure-curve control, and is suited to advanced baristas.
How do I clean the machine?
Clean the group head and portafilter daily, wipe the steam wand immediately after steaming, and use filtered water.
