Composed of the freezing cylinder (evaporator),
a Scroll Compliant rotary compressor, a high
efficiency condenser, an economiser, a
thermostatic valve and a number of minor
accessories. All these components are designed
specifically for operation at low temperatures
using R404A coolant gas.
Cooling is carried out by steam compression: the
compressor pumps gas into the condenser, where
it is cooled and liquefied, and the liquid gas then
passes through the thermostatic valve and is
vaporized in the freezer cylinder (transforming
into gaseous state once more) before returning
to the compressor and starting the cycle again.
Vaporization of gas in the freezing cylinder
removes heat from the ice cream mix, which

The electrical system consists of the operator
panel and the electrical panel which covers all
of the rear of the machine. The operator panel
may be used to activate or deactivate all machine
functions, adjust functions and indicate
anomalies. The electrical box at the rear contains
the main switch and all control and power
devices.

cools down; the heat is then disposed of in the
condenser, where it is transferred to the water
coming from the cooling tower (or well), heating
it.
A pressure switch valve assembled on the
condenser water circuit keeps condensation
pressure constant, independently of water tem-
perature.
The system mounted on the Frigus 600 is a
particularly efficient one which makes use of a
dependable, low maintenance Scroll compressor
which acts as a two-stage compressor with an
economiser to obtain considerable cooling
capacity and improved dependability.
