Options

Oiltronix - Longer lasting air-ends, lower operating temperature

Atlas Copco has always been aware that compressors are extremely sensitive to condensation in compressed air. We know for example, that just 1% of water in the oil reduces the lifetime of the bearings by 40%. The electronic controlled oil temperature system extends the lifetime of air-ends, compressor components, oil and the oil-separator. Additionally, and not insignificantly – it reduces the average oil temperature, prevents overheating and increases safety.

Oiltronix, the benefits

Better reliability

Higher efficiency

Better for the environment

Lower cost of ownership means: - longer life of the air-ends - longer life of the oil - longer life of the oil separator - longer life of the other compressor components - no draining, less down time



FuelXpert

Average 10% better fuel consumption than our best competitors

Conventional systems are based on pneumatically controlled engine speed and air inlet without accounting for fuel economy. These systems have focussed on the stabilization of the regulating system, but have not looked at the optimal fuel consumption at each load. FuelXpertTM, via the engine electronic control module, regulates speed and air inlet with a view to optimizing fuel consumption for each working condition. Importantly when the air demand is lower than the capacity required, the system ensures the right capacity for the application. The benefit is largery at partial load.

Principle Data

Compressor Element

The quality of a compressor can be measured through the reliability, efficiency and durability of the compressor element used. Through decades of expertise in the design of compressor elements, the result is the production of most efficient and reliable compressors on the market. When the screw element is efficient- durability excels, maintenance intervals increase and fuel consumption goes down.

Air/Oil Separator

Air and oil separation is achieved through a centrifugal oil separator combined with a filter element. Separators are available in CE, ASME, or SQL approved versions and are stamped accordingly.

Designed for a higher maximum working pressure, the separator is equipped with a sealed high pressure safety relief valve, minimum pressure nozzle, automatic blow-down valve, and pressure regulator.

Cooling System

The cooling system consists of an integrated side-by-side aluminium oil cooler with axial fan to ensure optimum cooling. The cooling system is suitably designed for continuous operation in ambient conditions up to +50°C, with all canopy doors closed.

Compressor Regulating System

The compressor regulating system consists of air filter, air receiver/oil separator, compressor element, unloader assembly with unloader valve, blow down valve and loading valve.

Economical power consumption is assured by the fully automatic step-less speed regulator that adapts engine speed to air demand.

Discharge Outlets

Compressed air is available from 1 x 2” outlet valve.



Engine

Caterpillar C-18

Caterpillar C-18 ACERT T3, COM III/Tier 3 compliant four-cylinder, liquid-cooled diesel engine provides ample power to operate the compressor continuously at full-load.

Engine output at rated speed, in accordance to SAE Standard, is 429kW at 1800 rpm.

The engine has the capability to start the compressor to -10°C without the addition of a cold start aid. Cold start options are available for up to -25°C.

The fuel tank is sufficiently sized to operate the unit for minimum of 8 hours at full-load condition.

Electrical System

The XRYS 557-577 Cd is equipped with a 24 Volt negative ground electrical starting system.

Instrumentation

The instrument control panel is located on the back, curb side of the compressor canopy, with a protective metal cover for safety and protection.

Standard instrument package includes a multi-functional control / scroll pad, operating pressure gauge, and 4-line LCD operations & diagnostic display with 400 lines of machine performance data.

Starting is achieved with a three position switch for ease of operation.

Bodywork

The compressor is delivered as standard with a zincor coated steel canopy with powder coat paint finish providing excellent corrosion protection. The canopy is sound attenuated to meet the most current legal noise requirements. Wide doors provide complete service access to all components.

Undercarriage

The XRYS 557-577 Cd compressor is available with numerous undercarriage alternatives, providing utmost flexibility in installation or towing requirements.

Support mounted version less undercarriage

Skid mounted

4-wheel wagon style undercarriage with or without ABS brakes

Manufacturing & Environmental Standards

The XRYS 557-577 Cd is manufactured following stringent ISO 9001 regulations, and by a fully implemented Environmental Management System fulfilling ISO 14001 requirements.

Attention has been given to ensure minimum negative impact to the environment.

The XRYS 557-577 Cd meets all current EU exhaust and noise emission directives.
