Ceado E37SL Overview The Ceado E37SL offers the same incredible performance as the E37S with its 83mm burrs, Quick Set gear, and Steady Lock system, but brings along one significant upgrade: Active Thermal Control. Features and Performance The Ceado E37SL marks a big step forward in the E37 series with Active Thermal Control, an exclusive feature for the E37SL. It's an electronic temperature control system that automatically ventilates heat from the grinding chamber so coffee is unaffected while grinding. With Active Thermal Control, coffee is kept consistently fresh while grinding. The SL's 83mm flat burrs and 500 W motor rip through coffee at a high rate, dispensing at about 4 grams per second. With the Steady Lock system, the burrs are kept at a constant distance, no matter how much work has been done. Grind adjustment is a breeze thanks to the Quick Set Gear, which smoothly shifts between grind sizes by rotating the adjustment knob. The touchscreen display offers natural and easy dose selection and adjustment as well. As a finishing touch, the E37SL is nearly silent while operating. Why You Should Get It The Ceado E37SL has all the build quality and performance of the Ceado E37S, one of the best espresso grinders on the market, but with the added upgrade of Active Thermal Control. If you're a discerning coffee enthusiast who cares deeply about freshness, this may be the next grinder you need for your coffee bar.
