Super silenziamento - Supersilencing

Structure

With support frame, hot galvanized sheet, painted with polyurethane

powder enamels at 180 ° C to ensure the best weather resistance.

Compressors

Three-phase hermetic compressors installed on rubber anti-vibrations,

complete with integral protection modules with PT100 drowned in engine

windings.

Fan

Special profile axial, directly connected to the external rotor motor with

IP54 degree of protection, complete with overtemperature protection of

the motor and grill.

Outdoor Heat Exchanger

For cooling only units, microcanal aluminum heat exchanger that

guarantees:

•

No galvanic corrosion (100% aluminum)

•

Reduction of refrigerant charge (up to 70%)

•

Long life even in very aggressive environments

•

∆P lower air side (up to 30%)

•

Good refrigerant distribution thanks to the special 3-step design.

For the heat pump version: Aluminum finned pack changers with pitch type

louver wedges and copper plated tubes with split circuits for maximum

evaporative efficiency and undercooling circuit to increase refrigeration

capacity.

Plant side Heat Exchanger

Plate type, stainless steel plates AISI 304, braided type.

Electric panel

Includes: General disconnector with door lock, fuses, fan and pump

compressor remote sensors, electronic board for the management of all

Analogic Input and Output, Digital Input and Output.

Control System (Microprocessor)

The units are equipped with a microprocessor that adopts a logic program

and regulates the overheating through an electronic thermostatic valve

monitored by the pressure transducer signals and temperature sensors.

The CPU also manages the following functions: water temperature control,

antifreeze protection, high and low pressure protection, compressor timing

adjustment, alarm management and alarm, operating LEDs. On request,

the microprocessor can be connected to a BMS remote control system.

Refrigerant circuit

The refrigerant circuit was built according to the UNI EN 13134 standard for

welding procedures. The refrigerant used is R410A. The basic refrigerant

circuit includes: electronic expansion valve, liquid separator, liquid receiver,

maintenance and control valves, pressure regulator according to PED

regulation, pressure transducers for precise setting of evaporation and

condensing pressures, High capacity drier filter. In addition to the heat

pump versions: the 4-way switch valve, the VEE capacity extension solenoid

valve and 4 switching valves to allow installation of any heat recuperators.

Hydraulic circuit

The copper pipe circuit includes: service valve and flow switch, antifreeze

sensor installed on the water supply pipe to the plant, safety valve, drain

cock, air vent valve and pressure gauge.
