Superior Engineering Hardware Built for Decades of Operation: Tan Long Mechanical & Refrigeration is both a direct manufacturer of sandwich panels and SUS304 evaporative condensers, and an authorized tier-1 OEM distributor for global compressor flagships (Bitzer Germany, Mycom/Mayekawa Japan, Kobelco Japan, Danfoss Denmark). Procuring through Tan Long saves contractors and facility owners 15% – 20% in intermediary distributor markups, backed by 100% authentic manufacturer CO/CQ documentation.
3. Strict CO/CQ Provenance Standards & OEM Authenticity Guarantees
In an industrial market crowded with refurbished second-hand compressors and counterfeit components prone to refrigerant leaks, motor burnouts, and high energy draw, Tan Long strictly maintains a company-wide policy: 100% brand-new, factory-sealed imported equipment:
Mandatory Documentation Delivered with Every Shipment
- C/O (Certificate of Origin): Legal Certificate of Origin (CO) issued by the Chamber of Commerce in manufacturing countries (Germany, Japan, Sweden, Italy).
- C/Q (Certificate of Quality): Factory Certificate of Quality (CQ) with hydrostatic pressure and performance test logs.
- Customs Clearance Declaration: Complete import VAT payment vouchers and transparent electronic customs declarations.
- Online Factory Serial Number Verification: Clients can scan QR codes on compressor nameplates to verify authenticity and activate electronic warranties directly on Bitzer, Mayekawa, or Danfoss portals.
Operational Hazards of Sourcing Uncertified Machinery
- Rewound stator windings spike inrush current, inflating electricity costs by 30 - 45%.
- Worn screw rotors degrade volumetric compression efficiency (dropping COP), leaving rooms unable to reach target sub-zero temperatures.
- Internal moisture contamination provokes oil acidification, causing catastrophic bearing seizure and motor failure.
- Disqualified from OEM spare parts and technical support during critical unscheduled downtime.
