Large steam boiler with total volume of 3.5L, water content approx. 2L. Standard temperature is set to 135°C for long lasting steam power

1. Heat exchanger in steam boiler pre-heats water flowing to the coffee boiler, thus decreasing possible temperature fluctuations in the coffee boiler

2. Large coffee boiler with volume of 2.1L. The high volume has a stabilising effect on the brew temperature

3. Heat neutral polymer dispersion block, no loss of heat, no baking on of oils and fats, remains clean longer

4. Individual electronic temperature controller for each boiler, displays in full easy view

5. Self-bleeding group

6. Pre-infusion cylinder ensures slow infusion process with step-less build-up of pressure to full extraction mode. This allows a finer grind, creating more  surface, so a higher yield in the cup, less chance of channelling, preventing  fines to travel down. Even with the pump running from start a double-spring loaded piston absorbs first rising pressure on coffee to allow for a longer  initial saturation of the puck
