Alcorn Cafe Engineering manufacture complete kits to enable you to install quality designed and engineered Shot Timers to your Gen1 or Gen2 Synessos.
If you have a manual espresso machine, then why not add;
allows for independant pre-infusion on each group head - just as featured on a Synesso Hydra. Note that this requires additional pumps, motors and modifications to the hydraulic systems on your machine, but this has been successfully carried out by Alcorn Café Engineering on many machines now.
allows for driving "4-Stage Ramping" - just as featured on a Synesso Hydra or Needle Valve Pre-Brew - just as found on a Slayer. Not that these features require additional parts and modifications to the hydraulic systems on your machine, but all have been achieved by Alcorn Café Engineering.
