components
Main components
5.1 Refridgeration Circuit
Compressor
High efficient scroll set on anti-vibration mounts, activated by a 2-
pole electric motor with built in heat protection.The compressor is
supplied as standard with anti-freeze protection which operates
automatically then the unit is connected to the mains supply.
Air-side coil heat exchanger
Made with copper pipes and aluminium louvered fins. Fitted with
protective grill.
Water-side plate heat exchanger
Externally insulated with closed cell material to reduce heat loss.
Liquid separator
Positioned at compressor intake to protect from refrigerant re-
turn.
Expansion valve
Mechanical valve with a capillary tube that regulates the flow of
refrigerant gas to the evaporator, depending on the heat load.
Filter drier
Mechanical dehydrator filter that removes impurities and any
traces of humidity present in the refrigerant circuit.
Liquid indicator
Used to check the refrigerant gas load and any presence of hu-
midity in the refrigerant circuit.
Solenoid valve
The valve closes when the compressor switches off, blocking the
flow of refrigerant gas to the evaporator.
4 way valve
Reverses the flow of refrigerant for the defrosting cycle.
One-way valve
Allows one-way flow of the refrigerant.
Liquid accumulator
Used to keep the refrigerant gas in the liquid state when the ma-
chine accumulates it excessively during functioning.
5.2 Frame and fans
Support frame
Made from weather resistant, powder coated galvanised sheet
steel.
Ventilation Unit
Helical type, balanced statically and dynamically. The electric
fans are protected electrically by magnet-circuit breakers and
mechanically by anti-intrusion metal grids, according to the IEC
EN 60335-2-40 Standard.
5.3 Hydraulic circuit
Differential pressure switch
Positioned on the inlet and outlet of heat circuit water on the
evaporator, it measures the pressure loss across the evaporator,
which is used to ensure there is adequate water flow.
Water filter
This allows to block and eliminate any impurities present in the
hydraulic circuits. It contains a filtering mesh with holes that do
not exceed one millimetre. It is indispensable in order to prevent
serious damage to the plate exchanger.
