6. Engineering
All parts used to manufacture the machine are of a suitable type and size in relation to power and
performance specifications. The SILENT c
ompres sor primarily consists of:
1) Soundproof cabinet
2) Reciprocating piston pump unit
3) Electrical components
4) Control and instrument panel
1) SOUNDPROOF CABINET
The cabinet features a streamline, modern design. It consists of a solid baseframe that supports the
uprights, which in turn support the upper frame. The outer casing consists of side and front panels and
a cover. The cabinet is epoxy powder coated and cured at 180°C. The panels are made of a soundproof
and self-extinguishing material to ASTM-D-1962-68 specifications. The baseframe is palletisable and
incorporates height-adjustable feet.
2) RECIPROCATING PISTON PUMP UNIT
The extensive range comprises single stage and dual stage compressors, from 1.5 to 18.5 Kw
(2HP÷25HP), all of which incorporate highly reliable pump units to meet the requirements of all
professional and industrial applications. In the SILENT1 version, the pump unit and motor are
assembled on a baseframe, which is fastened to 24 litre dampener; in the SILENT2 and SILENT4
versions, these assemblies are fastened directly to the structure by means of extremely efficient
vibration dampening pads. The air inlets on the cabinet are arranged in order to maintain the pump
unit cool at all times, to maximise efficiency and performance. The SILENT2 and SILENT4 versions
incorporate high-capacity electric fans that are controlled by a thermostat and operate independently of
the compressor.
3) ELECTRICAL COMPONENTS
Electrical panel
In the SILENT series, the electrical panel is installed inside a space at the front of the cabinet. In the
SILENT1 version, this panel is accessed by removing the cover. In the SILENT2 and SILENT4 versions
it can also be accessed by unscrewing the two screws on the top of the control panel and turning this
down. The panel is made of extremely reliable components and comprises power and auxiliary devices.
Motor
SILENT compressors incorporate single-phase electric motors with direct starting or three-phase motors
with direct or delta-star starting. Motors are built to class F insulation and IP54 protection. All models
incorporate thermal cutout devices.
