E61 Group Head
The famous E61 commercial group head is the same group head you will find in many cafe machines. Made from 4kg of chrome-plated brass, it provides excellent thermal stability vital for great espresso. The E61 passive pre-infusion system gently infuses your ground coffee with hot water at a lower pressure allowing the coffee to expand uniformly in the basket for superior coffee extraction.
The thermo-syphon system automatically circulates hot water through the group head while the machine is idle. Hot water flows from the heat exchanger into the group head through the upper pipe. As heat is transferred to the group head the water cools and leaves the group head through the lower pipe. Here the water combines with cold water from the pump and flows into the bottom of the heat exchanger. The continuous movement of hot water maintains the group head at a stable temperature vital for producing a consistently great espresso.
Dual pressure gauges
The double pressure gauges allow you to monitor the steam boiler pressure and the coffee brewing pressure from pre-infusion to final extraction.
Over Pressure Valve
An adjustable OPV (Overpressure valve) limits the group head pressure for optimal extraction.
Spring-loaded long life non-compression steam and hot water valves are easy to operate have a long working life.
No Burn Steam Wand
The steam wand produces a powerful dry steam ideal for texturing milk. The ball joint connection allows perfect positioning of the steam wand. The commercial soft-close valve provides easy steam pressure control with minimal wear. Cool-touch technology makes the wand easier to handle and easier to clean as milk is less likely to bake on.
