Semi-Hermetic Piston Compressor Factory Acceptance Test (FAT) Standard | Cold Storage Compressor Offline Test & Inspection Specification

Semi-Hermetic Piston Compressor Factory Acceptance Test (FAT) Standard defines factory test items, data recording and acceptance criteria; FAT verifies performance and integrity before compressor leaves factory. A professional refrigeration compressor supplier provides FAT test report with curve data, vibration, noise and tightness records; witness test can be arranged for purchaser’s inspector. Refrigeration compressor factory adopts IQC, IPQC and FQC three-stage inspection system; all test data is bound to compressor serial number and stored permanently. Refrigeration compressor manufacturer holds ISO9001 and ISO14001 certificates; export compressor models need CE and RoHS certification for overseas bidding. How to execute FAT includes visual inspection, tightness test, no-load running, full-load performance test, vibration & noise measurement and protection function verification. Refrigeration compressor comparison shows semi-hermetic piston FAT needs to verify capacity unloader action; this test item is not required for fixed-displacement scroll compressors. Xiteliduo semi-hermetic refrigeration compressor assigns unique serial number to every finished unit, binding material batch, assembly operator and all test data. Piston refrigeration compressor must pass 2.5MPa pressure holding air tightness test before delivery;
