Aquamerk kit:
    to control the water hardness:
     it’s an hardness control kit using different reagents to
    get the water hardness in French degrees


    to check the alcalinity:
    It’s a kit to get the detergent gr/liter in the machine
    wash basin

    Multi basin with conveyor belt




8
THE MACHINES:
       the single basin with fixed rack


    Washing capacity from 400 up to 1200
    dishes per hour

    Basin capacity from 30 up to 90 liters

    Only one rack for the dishes




9
THE MACHINES:
        the single basin with fixed rack


     Fixed or rotating washing spray jets over
     and below the dish rack

     Fixed or rotating rinsing spray jets over
     and below the dish rack
