PID Espresso Machine, DE1
​
The DE1 was co-designed by Brad Larsen and John Buckman to replace an espresso machine called the ZPM. The brand needed to stand apart from ZPM or the “Mr Coffee” look so inspirations were taken from professional espresso machines that have the group head extending from the body. This lowered the profile allowing for a tablet on top. As home espresso machines tend to tip over when tightening, a handle to the body. This is the only espresso machine with this innovation. The machine can boil water and steam milk while maintaining case temperatures acceptable to UL. Three initial prototypes were built with a 200-part BOM. All functioned as planned and were demonstrated in many places around the world. This machine is produced in Tsuen Wan, Hong Kong.
Electro Mechanical Design for U/UE compliance. Hong Kong factory
Software can be written with clever safety measures but UL will not accept them. Brad Larsen was the liaison to UL Hong Kong to make sure electro mechanical design was in compliance.
