Finned Tubular Heater Project Acceptance Checklist & Site Handover Document
Finned tubular heater site acceptance is divided into visual inspection, electrical test, thermal performance test and documentation verification four major modules. Finned tubular heater visual acceptance items: tube surface coating integrity, fin tightness, mounting alignment, sealing gaskets, cable routing and terminal protection. Finned tubular heater electrical acceptance test: cold resistance check, insulation resistance ≥50MΩ, 1500V AC withstand voltage, leakage current measurement. Finned tubular heater thermal performance acceptance: run at rated airflow and power for 2 hours, record air temperature rise, pressure drop and hot spot temperature. Chuanli Cold Storage Electric Defrosting Tubes provides standard acceptance checklist and handover technical dossier for cold storage evaporator heater projects. Finned tubular heater documentation handover includes: factory test report, material certificate, wiring diagram, maintenance manual, spare parts list and warranty certificate. Finned tubular heater acceptance pass criterion: measured air temperature rise within ±6% of design value; pressure drop within ±10% of calculated value. Finned tubular heater acceptance must verify interlock function: airflow loss protection, over-temperature sensor and thermal fuse tripping function. Finned tubular heater site acceptance shall be recorded with photos and test data; all signed documents become part of project asset archive. Finned tubular heater defects found during acceptance are classified as minor/major; major defects must be fully rectified before formal handover. Finned tubular heater site acceptance validates mechanical integrity, electrical safety and thermal performance before formal project handover and warranty activation.
