    9. If compressed air is used in the food industry and more specifically for direct food contact, Atlas Copco recommends, for optimal safety, the use of certified Class 0 compressors in combination with appropriate filtration depending on the application. Please contact your Atlas Copco Customer Center for advice on specific filtration.

  • Page 10: Safety Precautions During Operation

    Instruction book 14. In multiple compressor systems, manual valves must be installed to isolate each compressor. Non- return valves (check valves) must not be relied upon for isolating pressure systems. 15. Never remove or tamper with the safety devices, guards or insulation fitted on the machine. Every pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure must be protected by a pressure relieving device or devices as required.

  • Page 16: Oil System

    Instruction book Description Air drawn through filter (AF) and open inlet valve (IV) into compressor element (E) is compressed. A mix of compressed air and oil flows into the air receiver/oil separator (AR) via check valve (CV). The air is discharged through outlet valve (AV) via minimum pressure valve (Vp) and air cooler (Ca).

  • Page 17: Cooling System

    Instruction book Description In air receiver/oil separator (AR), most of the oil is removed from the air/oil mixture by centrifugal action. The remaining oil is removed by oil separator (OS). The oil collects in the lower part of air receiver/oil separator (AR), which serves as an oil tank.

  • Page 18: Condensate System

    Instruction book Description The cooling system comprises air cooler (Ca) and oil cooler (Co). On air-cooled compressors, the cooling air flow is generated by fan (FN). Condensate system Water drains Condensate drains, typical example Reference Designation Automatic drain connection Automatic drain connection of the dryer (only on Full-Feature units) Next to each automatic drain outlet is a manual condensate drain connection for manually draining of the condensate.

  • Page 25 Instruction book Refrigerant circuit Compressor (5) delivers hot, high-pressure refrigerant gas which flows through condenser (6) where most of the refrigerant condenses. The liquid refrigerant flows through liquid refrigerant dryer/filter (7) to thermostatic expansion valve (8). The refrigerant leaves the thermostatic expansion valve at evaporating pressure. The refrigerant enters evaporator (2) where it withdraws heat from the compressed air by further evaporation at constant pressure.

  • Page 26: Elektronikon Ii Regulator

    Instruction book Elektronikon II regulator ® Elektronikon II regulator Control panel General In general, the Elektronikon regulator has following functions: • Controlling the compressor • Protecting the compressor • Monitoring components subject to service • Automatic restart after voltage failure (made inactive) Automatic control of compressor operation The regulator maintains the net pressure between programmable limits by automatically loading and unloading the compressor.
  • Page 27 The regulator has a built-in function to automatically restart the compressor when the voltage is restored after voltage failure. This function is deactivated in compressors leaving the factory. If desired, the function can be activated. Consult the Atlas Copco Customer Centre. If activated, and provided the regulator was in the automatic operation mode, the compressor will automatically restart if the supply voltage to the module is restored within a programmed time period.
