Compressor Inspections
PSSR examinations for piston, screw and rotary compressors in industrial, workshop and commercial settings.
LDN Inspection Services provides statutory PSSR examinations for all types of compressors and compressed air systems. Our qualified pressure systems engineers examine compressor units, receivers, safety devices and associated pipework, delivering clear digital reports and written schemes of examination.
Compressor PSSR Examinations
Compressors and their associated pressure systems fall under the Pressure Systems Safety Regulations 2000 (PSSR). Whether you operate a small workshop piston compressor or a large industrial screw compressor, the stored energy in the compressed air system can cause serious injury if a failure occurs. PSSR requires that these systems are properly examined by a competent person.
Compressor systems include not just the compressor unit itself, but also the air receiver, aftercooler, dryer, safety valves, pressure gauges and all connecting pipework. All of these components form part of the pressure system and must be included in the written scheme of examination and subjected to regular thorough examination.
Our PSSR examinations cover the complete compressor system. We assess the condition of all pressure-containing components, test safety devices, and provide clear reports with defect categorisation and recommended actions to keep your compressed air system safe and compliant.
Key Requirements
- A written scheme of examination covering all pressure components
- Thorough examination by a competent person at specified intervals
- Safety valves and protective devices must operate correctly
- Safe operating limits clearly defined and not exceeded
- Examination reports retained and defects acted upon promptly
