Tractor ac compressor

Buyers must prioritize compatibility and durability. Key specs include the displacement (cc/rev) to ensure cooling capacity matches the cabin size, and the clutch diameter and groove type (e.g., 1PV, 2PV, or Multi-groove) to align with the engine belt system. Ensure the compressor uses R134a or R1234yf refrigerant as per regional environmental laws. For heavy-duty use, look for swash plate or scroll designs which offer higher efficiency and lower vibration compared to older piston models.

Request ISO/TS 16949 or IATF 16949 certification, which are the gold standards for automotive and machinery parts manufacturing. Ask for salt spray test reports (to check for corrosion resistance in humid farm environments) and durability cycle test data (ideally exceeding 500+ hours of continuous operation). High-quality units should feature Japanese or high-grade international bearings (like NSK or SKF) to prevent premature clutch failure.

The main issues are mounting ear configurations and port orientations (Vertical vs. Horizontal O-ring/Flare). Even if the model number matches, the voltage (12V vs. 24V) and connector plug type may vary. It is highly recommended to provide the OEM part number and clear photos of the original unit's nameplate to the supplier on Made-in-China.com to ensure a 100% fit.

The compressor must be installed with a new receiver drier and expansion valve to maintain the warranty. Advise using the correct PAG oil viscosity (e.g., PAG 46 or PAG 100) as specified by the manufacturer. System flushing is mandatory if the previous compressor suffered a mechanical internal failure (black death) to prevent metal debris from destroying the new unit.

Utilize Secured Trading Services on Made-in-China.com to protect your payment until delivery. Explicitly state in the contract that 'all units must be 100% brand new with zero hour usage'. Request a pre-shipment inspection (PSI) by a third party like SGS or Intertek to verify internal components and pressure-test a random sample from the batch.

For tractor compressors, MOQs are often flexible (e.g., 10-50 units). Negotiate based on annual volume rather than a single order to secure tier-2 or tier-3 pricing (typically 15-25% lower than sample prices). Ask for 'CKD' (Completely Knocked Down) pricing if you have local assembly capabilities to save on import duties in certain jurisdictions.

Compressors are heavy and contain oil; they must be shipped in reinforced double-corrugated cartons with custom foam inserts to prevent casting cracks during transit. Ensure the supplier plugs all ports with plastic seals to prevent moisture ingress. For sea freight, request palletization with shrink-wrap to avoid humidity-induced oxidation on the clutch plates.

Check the HS Code (typically 841430) for specific import tariffs in your country. Be aware of Anti-Dumping Duties that may apply to certain mechanical components from specific regions. Ensure the supplier provides a Certificate of Origin (CO) to take advantage of Free Trade Agreements (FTAs) which can reduce or eliminate import taxes.
