1. Secure Packaging and Shock Absorption
Before transportation, it is crucial to package the compressor in a manner that protects it from shock, vibration, and external impacts. Semi-Hermetic Compressors contain delicate internal components such as pistons, bearings, crankshafts, and motor windings, which can be easily misaligned by external forces. High-density foam inserts, rubber mounts, or shock-resistant wooden crates should be employed to absorb vibrations during transit. The compressor must be immobilized within the packaging so that it cannot shift, preventing any mechanical stress that could compromise tolerances or create micro-fractures in critical components. Specialized transport crates designed for heavy-duty compressors with built-in suspension systems can further minimize the risk of damage during long-distance shipment.

2. Maintain Upright Orientation
Transporting a Semi-Hermetic Compressor in an upright position is essential to prevent oil migration and ensure proper lubrication upon startup. Compressors contain oil reservoirs designed to lubricate bearings, pistons, and other moving parts. Tilting, inverting, or laying the compressor on its side allows oil to pool away from critical lubrication points. This can cause components to operate under dry conditions at initial startup, increasing friction, wear, and the likelihood of early failure. Labels indicating “This Side Up” and orientation arrows should be affixed to all packaging, and transport personnel must be trained to follow these instructions strictly.

3. Prevent Contamination Exposure
Semi-Hermetic Compressors are highly sensitive to external contaminants such as dust, dirt, and moisture. Even minor particulate matter entering the suction or discharge ports can obstruct internal oil passages, clog filters, and cause corrosion over time. To prevent contamination, protective caps must be securely fitted on all openings, and the compressor should be handled in clean, controlled environments whenever possible. During storage and transit, the compressor should remain in its sealed packaging, and additional coverings such as moisture-proof bags can provide extra protection against environmental exposure. Contamination not only reduces efficiency but also accelerates wear of internal moving components.

4. Temperature and Humidity Control
Extreme temperatures and high humidity during storage or transport can adversely affect the internal oil and the compressor’s metallic components. High ambient heat can thin the lubricant, reducing its viscosity and compromising its ability to form a protective film over moving parts. Conversely, extremely low temperatures can thicken the oil, impeding proper flow during initial startup. Moisture can condense inside the system, leading to corrosion, acid formation, or reduced dielectric strength of electrical components. Controlled-environment transportation, insulated packaging, and humidity-resistant sealing are recommended for long-distance or international shipping.

5. Minimize Manual Handling
Frequent manual lifting and repositioning increase the risk of accidental drops or impacts. Semi-Hermetic Compressors are heavy and contain precision-engineered components, making improper handling potentially catastrophic. Use mechanical lifting devices such as forklifts, cranes, or hoists equipped with properly rated slings, chains, or lifting brackets designed for the compressor’s weight and center of gravity. Personnel must avoid lifting by suction/discharge ports, motor housings, or other non-load-bearing sections. Proper handling reduces mechanical stress, prevents deformation of the casing, and minimizes the risk of internal misalignment.

6. Pre-Installation Storage Practices
After transport, compressors should be stored in clean, dry, temperature-stable environments, ideally in their original packaging. Extended storage without proper environmental control can result in oil settling in one part of the compressor, leading to uneven lubrication. The storage area should protect the unit from dust, corrosive gases, and physical impact. Protective caps on ports must remain in place until installation, and the compressor should be placed on stable surfaces, avoiding areas prone to flooding, vibration, or excessive heat. Regular inspection of storage conditions ensures the unit remains in ready-to-use condition.
