Air Cooler Factory Test, Packing & Sea Freight Export Protection
Factory inspection of air cooler reduces overseas on-site fitting failure, leakage and deformation damage during long sea transportation. Standard test items: coil nitrogen pressure holding test at 25 bar for 12 hours, visual fin inspection, fan rotation test, defrost heater resistance test. Coil pressure drop >0.3 bar within holding period is judged unqualified; weld leakage will be repaired and retested before packing. Fin collision and bending is the most common damage during shipment; protective plastic grid cover is installed on air inlet and outlet side. Xiteliduo air cooler HS 84186120 is packed in fumigated wooden case with foam cushioning, desiccant bag and anti-rust agent for sea container transport. Air cooler for rack system will mark each refrigerant circuit clearly on nameplate and piping port, avoiding cross connection during overseas installation. Blast freezer air cooler with wide fin coil needs extra rigid bracket inside package to prevent coil twisting under stacking pressure. All electrical terminals of air cooler are sealed with waterproof cap; salt fog and moisture inside container easily cause short circuit of heater and fan wiring. Complete shipment documents include dimension drawing, wiring diagram, defrost parameter table and spare parts list for commissioning team. Refrigeration exporter inspects container loading method; air cooler cannot be placed under heavy cargo to prevent casing deformation and coil crush.
