1) General Description
The machine is built in 1 and 2 coffee
group versions and is essentially composed
of the following parts:
• Inlet and outlet boilers if one group
machine or boiler 1 / boilers 2 if two
groups machine;
• Brewing tap(s);
• Water pump.
2) Description of the various parts
• Coffee Boilers
The Coffee Boiler consists of a cylindrical
tank made of AISI 300 series stainless
steel. Each unit is subjected to a hydraulic
test, at a pressure of 18 bar, and has an
operating pressure of 9 bar. The following,
is the effective volumes:
2 coffee boilers 1.4 liters each
Covers are welded at either end of the
cylindrical tank and on one of them there
is a housing for the water heating elements.
The temperature of the coffee boiler is
maintained by an electronic temperature
controller (PID capable) with an accuracy
of 0.2°C.
It consists of AISI 300 stainless steel
tubes. Heating is accomplished through an
immersion-type plated heating element.
• Operating temperature 95°C
(adjustable), controlled automatically
by an electronic temperature controller
with an accuracy of 0.2 °C. Operating
pressure of 9 bar.
• Pressure is displayed through a pressure
gauge with a scale from 0 to 18 bar.
• Safety device, based on an expansion
type mechanical valve, with
ounteracting spring adjusted to 13 bar.
• Testing: Hydraulic test at 18 bar
performed on ready-to-use small boilers,
at our factory.
• Brewing groups
They consist of a precision casting made
of stainless steel. The brewing group
accepts the portalter used to hold the
ground coffee; the espresso ows through
the brewing group, through the portalter
basket, through the portalter spout, and
into the cup(s) after the brewing button
has been pressed.
• Exterior cover
The exterior consists of painted and
stainless sheet steel panels. To provide
good aesthetics, to optimize ergonometrics
for the operator and to reduce the chance
of damage to a minimum.
• Water pump
The rotary vane pump, is installed on the
water supply tubing and is set up to operate
anytime the coffee groups are activated,
and through an autoll system whenever
the water boiler needs to be replenished.
