The PED applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure PS greater than 0.5 bar.
Many component of the compressors air system may belong to PED, for example:
- piping including any kind of connectors classified according article 1.3 (e.g. in compressed air systems);
- air coolers / heat exchangers (s. art. 188.8.131.52);
- filter / separator housings;
- safety/relief valves;
- pulsation dampers;
- vessels and reclaimers not included in SPVD (87/404/EEC)
When the air compressor package contains pressure equipment of category I not covered by Machinery Directive (e.g. exclusion of pressure vessels, art. 1 sec. 3) and pressure equipment of category II to IV, the result should be seen as an assembly according to the PED.
More Information is given on the PED web site from the European Commission.
The Simple Pressure Vessel Directive
The SPVD applies to simple pressure vessels manufactured in series.
Simple Pressure Vessel' means any welded vessel subjected to an internal gauge pressure greater than 0,5 bar which is intended to contain air or nitrogen and which is not intended to be fired.
The parts and assemblies contributing to the strength of the vessel under pressure shall be made either of non-alloy quality steel or of non-alloy aluminium or non-age hardening aluminium alloys.
The SPVD does not include the notion of assemblies.
Typical Simple Pressure Vessels installed in a compressors package are oil separator vessels and air receivers.
More Information is given on the SPVD web site from the European Commission.
Sustainability projects and low carbon initiates need compressed air, gas and vacuum equipment
Increasing concern about the environment and the need to foster energy efficiency are addressed by the European Climate Change Programme and its subsequent legislative measures. Pneurop supports the overall sustainable energy policy objectives of the European Union within the sphere of its responsibilities. Its members companies actively promote energy efficiency for the benefit of their customers as part of their daily business activity.
