The professional-grade Isomac Pro Dual Boiler PID Coffee Machine is designed to give small coffee bars, offices, or prosumer kitchens the power of high-end espresso without breaking the bank. With dual boilers, PID displays, and the classic E61 group, it’s a great pick for spaces where a lower-end home machine won’t do the trick. Professional Espresso Power Two boilers run this machine: a 1.8L steam boiler and a 0.6L coffee boiler. The temperature of each boiler can be controlled with the accompanying PID display on the front of the machine, offering a high degree of control and confidence you won’t find in smaller machines. The dual boilers enable you to steam milk and pull shots simultaneously without one ever affecting the other—a much better setup for serious espresso stations. And since you can either use the included 2.9L water tank or plumb the machine directly into your water line, you won’t be needing a water refill anytime soon.
