The Ascaso Steel PID Duo is a semi-professional coffee machine for home, offices, shop or small café. The machine is designed by the Ascaso Factory Team to meet the requirements of the expert user. It is manufactured with the highest quality materials (aluminum, stainless steel, brass), and a minimum use of plastic. This version is equipped with a Ø 58mm filter holder and active PID control. This allows you to manage the temperature of your thermostat with high precision. As a result you will have more variables to play with and more control over the quality of your espresso coffee. Having two groups means that you have separate hot water supply for tea on demand. Simply great for your office coffee set-up.
