2. DESCRIPTION
The machines in the S20 series have been designed
to prepare espresso coffee and hot beverages.
A positive-displacement pump inside the machine
powers the heater in which the water is heated. By
pressing the appropriate buttons, water is supplied
to the spouts in the form of hot water or steam,
according to needs.
In the model with an economizer, the water to be used
for the beverages is supplied directly by the water
supply, pressurized by the pump and immediately
heated by the steam produced by the boiler.
Model S24 has an incorporated water-tank and does
not, therefore, need to be connected to the
waterworks. A water-softener inside the tank softens
the water, filtering the calcium salts in it.
The machine consists of a steel supporting structure
on which the mechanical and electrical components
are fitted. These are completely covered with panels
in varnished steel and stainless steel.
The beverages are dispensed at the front of the
machine, where all the buttons, control devices and
dispensers are to be found.
There is a cup-warming plate on the top of the
machine.
