Used Air Compressor Ingersoll-Rand CENTAC C100MX3-2SH 8.23 bar General
Description of the Used Air Compressor Ingersoll-Rand CENTAC The Used
Air Compressor Ingersoll-Rand CENTAC C100MX3-2SH 8.23 bar efficiently
meets industrial compressed air supply needs. Consequently, its
advanced structure ensures reliable and continuous operation.
Furthermore, a three-phase electric motor directly couples through a
gear-type spacerless coupling, optimizing performance by minimizing
mechanical losses and improving power transmission. This compressor
belongs to the Low Pressure category, operating at a maximum pressure
of 8.23 bar absolute, which is equivalent to approximately 7.23 bar
relative to atmospheric pressure. As a result, its design makes it
ideal for industrial applications that do not require pressures
exceeding 10-15 bar, ensuring stable and efficient operation. The
machine utilizes a three-stage compression configuration, which
progressively increases air pressure. Additionally, each stage
features combined aluminum and cast iron diffusers, while a cooling
system with intercoolers at each stage and a final aftercooler
enhances operational efficiency. Moreover, onboard instrumentation
includes temperature and pressure transducers, ensuring continuous
performance monitoring. Technical Data and Performance The Used Air
Compressor Ingersoll-Rand CENTAC C100MX3-2SH 8.23 bar operates with an
absolute intake pressure of 99.3 kPa, whereas its discharge pressure
reaches 8.23 bar absolute. It delivers an air supply capacity of 2190
m³/h, making it highly suitable for large-scale industrial
applications. Its three-phase asynchronous squirrel cage motor runs
within a voltage range of 380 to 415V, at 50 Hz, providing a nominal
power of 680 kW and a rotational speed of 2970 RPM. Similarly, the
motor features an IP23 protection rating and Class F insulation,
allowing a maximum operating temperature of 100°C. Given these
specifications, a star/delta starting configuration limits the number
of starts to three when cold and two when hot per hour, thereby
preventing excessive thermal and mechanical stress. Structure and
Components A vertically split cast iron casing enhances the
machine’s robustness, facilitating easy maintenance and quick access
to internal components. In particular, the Bull-Gear, constructed from
AGMA 12-grade helical steel, operates with oil-lubricated hydrodynamic
sleeve bearings, ensuring reliability and longevity. Furthermore, the
17-4PH stainless steel impellers feature a semi-open design with
backward-leaning blades to maximize aerodynamic efficiency. In the
same way, aluminum and cast iron diffusers aid in pressure recovery
and maintain operational stability. The lubrication system integrates
an oil reservoir coated with epoxy for corrosion resistance.
Additionally, a 0.75 kW pre/post lubrication pump, operating at
380/415V, maintains continuous oil circulation, protecting moving
components. Meanwhile, the main oil pump, a positive displacement
type, directly connects to the compressor shaft. Also, a 10-micron
cartridge filter purifies the oil, while a fixed bundle shell and tube
heat exchanger keeps the oil temperature within optimal limits,
allowing a maximum cooling water temperature of 25°C. In order to
prevent thermal fluctuations, a 2100 W oil reservoir heater ensures
consistent oil temperature. Control and Safety System This Used Air
Compressor Ingersoll-Rand CENTAC incorporates an MP3 Microcontroller,
which manages pressure regulation, start/stop cycles, and real-time
temperature and pressure monitoring. Specifically, key integrated
safety features include: Real-time monitoring of temperature and
pressure transducers for each stage Overheating protection via a
dedicated thermostat A low water flow sensor that triggers automatic
shutdown An intuitive control panel for precise pressure adjustments
The system operates in two distinct modes: MODULATE, which maintains
constant pressure by adjusting the inlet valve, and AUTO-DUAL, which
combines modulated regulation with automatic load/unload management,
adapting to system demand. Manuals and Documentation of the Used Air
Compressor Ingersoll-Rand CENTAC To assist users, the compressor
includes comprehensive documentation. Notably, this documentation
includes: An installation and maintenance manual, detailing periodic
checks and servicing procedures A control panel user guide, explaining
microcontroller functions and adjustable settings Detailed technical
datasheets, covering operational specifications and parameters
