4.3 Machine description
• The structure is made of thick galvanised sheet metal painted with epoxy powders. The panels
of the compressor compartment are totally soundproofed by means of a sheet with high
soundproofing characteristics. The compressor compartment is accessible via removable front
panels.
• All models are equipped with BLDC TWIN ROTARY INVERTER airtight compressors suitable
for operation with R410a refrigerant. The compressors are mounted on rubber supports to
eliminate vibrations transmitted to the frame and are positioned on a metal damping structure.
• The air side heat exchangers are batteries made up of copper pipes and aluminium fins with
hydrophilic treatment.
• The fans are of the axial type with 4-pole motors and wing profile blades.
• The water side heat exchanger is of the AISI 316 steel plate type, covered with a closed-cell
anti-condensation mat.
• The heat pumps consist of a cooling circuit made entirely of copper and insulated with
expanded closed-cell pipe; the joints are braze-welded with high strength alloy. The circuit is
complete with: dehydrator filter, cycle reversing valve, liquid receiver, high pressure switch,
high pressure transducer for condensation control and low pressure transducer used both as
safety device and for electronic expansion valve control.
• The electronic expansion valve is made of high quality materials (AISI 316L and
technopolymers). Thanks to its proportional modulation and its high reliability, it guarantees
the ability to stabilise and maintain the operation of the heat pump in a very short time,
allowing energy savings.
• The hydraulic circuit consists of a single primary cell.
• The electrical panel is made of galvanised steel sheet and located in the compressor
compartment with a support plate for components. The power circuit is separate from the
control circuit and is designed in accordance with EN60204-1.
• System:
it includes inverter-controlled circulation pump, expansion vessel, filling port,
water discharge and water flow safety device (differential pressure switch).
