Italian Craft Meets Innovation
Built for professional baristas and coffee labs, this single dosing grinder is best described as a precision instrument designed to help you explore coffee’s sweet spot with a scientific approach and reliable repeatability. Paired with a high end espresso machine, it takes a commercial café’s flavor development to the next level.
Variable RPM control
One of the defining features of the E37Z Hero is the Z Hero Station, a separate control unit. It handles power, cooling fan control, and an RPM adjustment dial, allowing baristas to fine tune speed continuously from about 600 to 1500 rpm.
Because grind speed is adjustable, a parameter most grinders keep fixed, you can test how different RPM settings change the flavor profile, even with the same coffee and the same grind setting.
For those who want lab level control over extraction, or repeat a targeted taste across different menu items, this is a commercial grinder that lets you make RPM part of the recipe.
The Ultimate Core
At the heart of the machine is a massive 3.3 inch flat burr set. Both the burrs and the grinding chamber are finished with a diamond-like carbon (DLC) coating.
DLC is used in applications that demand extreme durability and very low friction, including F1 and NASCAR engine components and medical devices such as artificial heart pumps. The E37Z Hero takes full advantage of those same properties.
With its high hardness and wear resistance, the burr set is rated for an estimated lifespan on the order of about 22,000 lb of coffee, far beyond typical steel burrs at around 1,300 lb. Because it does not rust, you can use RDT, a light misting technique to reduce static, without hesitation. And thanks to the low friction surface, it generates less heat and greatly reduces grounds sticking or packing inside the grinder.
In addition, Ceado’s proprietary burr design uses different geometries for the upper and lower burrs, three protrusions on the top burr and two on the bottom. The burr surfaces also have no screw holes that could trap grounds.
This design approach allows the grinder to cover the full range with one unit, from ultra fine Turkish style grinding to coarse grinds for French press and cold brew.
Zero retention design with powerful drive
The E37Z Hero carries forward the E37Z series philosophy with a true zero retention design.
- A 45 degree tilted grinding chamber
- A slick internal surface finished with diamond-like carbon（DLC）coating
Thanks to these two elements, grounds flow out smoothly through the combined effect of gravity and low friction, pushing retention, grounds left from the previous shot, as close to zero as possible.
The motor is a high power 740 W class unit, compared with about 450 W on the E37S. This output may seem almost overengineered, but it’s present to handle demanding professional conditions with ease, including long continuous use and harder beans from darker roasts.
After extended grinding, it is recommended to manage cooling fan operation from the Z Hero Station, showing a thoughtful balance between performance and durability.
4 Reasons Professionals Choose It
- Single dosing with true zero retention: Each dose starts clean, making it ideal for cafés and labs that switch coffees often.
- Variable RPM as another key parameter: With the Z Hero Station, you can make RPM part of the recipe, letting you test how speed alone changes flavor and dial in extraction with much finer control.
- 3.3 inch flat burrs built for the full range: It is not just for espresso, it also covers drip, pour over, and cold brew. That versatility makes it a great fit for cafés that cannot justify multiple dedicated grinders.
- Repeatability during cleaning and maintenance: Calibration remains stable even after disassembly and reassembly, which is key for cafés that need consistent flavor with minimal daily maintenance.
3 Key Benefits
Reduced Bean Waste
Built for true zero retention, it minimizes purging when switching coffees, reducing waste and keeping costs in check.
More Menu Options
Because you can fine tune RPM and grind size to highlight the character of distinctive coffees, single origins, Gesha, natural process, and more, it becomes easier to craft a menu defined by flavor.
Brand Impact
With its premium build and lab like presence, having it in view behind the counter sends a clear message that your café takes coffee seriously.
E37Z-Hero――
A commercial single dosing grinder for professionals who want to push coffee further, not just by intuition, but with intention and repeatable results. For cafés and coffee labs that take flavor seriously, it goes beyond equipment and becomes a true partner in exploration.
