ISO 50001: Energy Management Standard

Monitoring: The Missing Link
ISO 50001 has been designed for companies of all sizes to use the Plan – Do – Check – Act process to continually improve energy management systems. Businesses complying with ISO 50001 will experience:

  • Cost savings
  • Quality improvement
  • Risk mitigation

The missing link in the PDCA cycle is often the “Check.” Airleader Intelligent Monitoring Systems are designed to gather important baseline data on your compressed air system for your energy management system.

Airleader provides data to verify demand side system improvements were successfully made and the self-learning system provides continuous monitoring with early warning signals when your system strays from set limits. Airleader monitoring can help your compressor operator stay on top of the supply and demand side of your system. The small investment can result in

  • Energy savings
  • Reduced CO2 emissions
  • Maintain energy savings
  • Capital equipment expenditures

ISO 8573-1

Air Quality classes defined in ISO 8573-1
There are standardized compressed air quality classes which makes easier for manufactures to define required air quality to ensure trouble free operation of their equipment.

The ISO specify 3 major contaminants of compressed air – solid particles, water and oil. These contaminants are specified by 3 digits that are referring to purity class from table below.

Particle size and density – Definition of the size and concentration of solid matter particles like dirt or rust that may remain in the compressed air.

Pressure dew point – Definition of the temperature to which the compressed air can be cooled without condensation of the moisture it contains. The pressure dew point changes with the air pressure.

Oil content – Definition: Residual quantity of aerosols and hydrocarbons contained in compressed air.

Selecting an air purity class of 2.4.1 specifies the following air quality when operating at the standard’s reference conditions:

Class 2 Particles
In each cubic meter of compressed air, no more than 100,000 particles in the 0.1-0.5 μm size range are allowed
In each cubic meter of compressed air, no more than 1,000 particles in the 0.5–1 μm size range is allowed
In each cubic meter of compressed air, no more than 10 particles in the 1-5 μm micron size range is allowed

Class 4 Water
A pressure dew point of +3°C or lower is required; no liquid water is allowed

Class 1 Oil
In each cubic meter of compressed air, not more than 0.01mg of oil is allowed. This is a combined level for both oil aerosol and oil vapor.

Definition micrometer [μm]
1 μm = 0.001 mm, or about 0.000039 inch
1 μm = 1.0×10−6 m = 3.2808×10−6 ft. = 39.370×10−6 inch
