Cold Storage Refrigeration Compressor Purchase Guide | Notes and Pitfalls to Avoid
Cold storage refrigeration compressor procurement failure rate can be reduced by 63% with standardized inspection checklist. xiteliduo Refrigeration Compressors sorts out key check items for buyers to avoid procurement risks.
Piston refrigeration compressor delivery inspection should verify nameplate parameters. The deviation of rated cooling capacity must not exceed ±5% compared with data listed on product certification.
Semi-hermetic refrigeration compressor quality verification needs to check pressure test record. The unit must pass 1.5 times design pressure air tightness test before factory delivery.
About 31% of procurement disputes come from mismatched working condition definition. Buyers need to confirm evaporating temperature and condensing temperature before signing supply contract.
Refrigeration compressor factory audit shall confirm production capacity. Reliable manufacturers should own at least one independent testing bench for continuous performance test of finished units.
