Curved stainless steel housing, front-mounted pressure gauges, and custom grouphead, but it is what you’re not seeing that rounds out the entire package. The commercial grade internal components were selected by German engineers at ECM for superior performance and build quality.
Before getting into the internals of the machine, the housing and frame deserve a special mention. Made of curved stainless steel, the machine is gorgeous to look at, but it’s important to note that the frame is actually one solid piece. To save money, some companies will weld the drip tray onto the body of their machine. Not content with cutting corners, ECM has actually built the drip tray as part of the frame, making it far more durable. Additionally, the body of the machine has been designed to absorb noise produced by the internal components, which, when coupled with the much quieter rotary pump, results in a near-silent brewing process.
The machine uses a 2.1 liter stainless steel, heat exchange boiler and the aforementioned rotary pump. Stainless steel is known for its heat retention and ability to resist corrosion. The heat exchanger allows you to brew and steam at the same time. Similar to the design of commercial machines, the boiler is mounted horizontally by a solid bracket to protect it from from shifting during shipping. The boiler is heated by a 1400 watt heating element and the pump is monitored by a Sirai pressure stat. Temperature stability is promoted throughout the machine, not only by the boiler but by the E61 group head and chrome plated brass portafilters as well. This unit comes with both a single and double spouted portafilter.
It can connected to a water line, eliminating the need to refill. This is made easier by the fact the the flow is controlled by a valve, located on the bottom of the machine, allowing you to manually switch from one water source to the other. The water reservoir holds 3 liters of water.
