Professional coffee machine ACS Vostok, 1 group

A new flagship in LSM group panorama.

The new Vostok single group is equipped, besides of the main control panel, with an innovative dosing system, to control the group with additional unique features.

On the main display, not considering the standard functions, you can set the preinfusion pressure that will be controlled electronically.

On the additional board you can work in 2 ways: by time or pressure. When the time mode is selected you can set 2 different duration of total infusion, when the pressure mode is selected you can set 2 different pressure to end the shot. In both cases during the shot when the values are reached the water in excess will be discharged, as well as the residual pressure in the group. The preferred way is by pressure because at a certain pressure a precise quantity of water will flow out.

We have checked that independently from the grinding or qty of coffee at a certain pressure the volume of the coffee it’s always the same. Of course there is always the possibility to stop the brewing manually, there are 3 buttons to program the board in an easy way and this display will be positioned on the left side between the group and steam or water tap.

Also, there are 2 timer on the display, the top is the preinfusion and the bottom the infusion.  In the setting you can set and then visualize the pressure set or the time set.

Actually this functions are unique on the lever machines scenario and we hope that our customers will appreciate.
