In cold storage installation, one easily overlooked detail—the bending of refrigerant pipelines—can harbor fatal risks! Many installations take shortcuts, directly making a hard 90-degree bend when turning pipelines horizontally upward without reserving a U-shaped oil return bend. This prevents the lubricating oil from smoothly returning to the compressor, causing it to accumulate inside the evaporator instead.

           It's important to note that lubricating oil is the "lifeblood" of the compressor, responsible for lubricating and cooling its core components. Once the return flow is obstructed, it not only reduces refrigeration efficiency and leads to inaccurate temperature control—posing risks of spoilage for fresh and frozen goods—but also causes oil starvation, wear, and overheating in the compressor. This can trigger system failures or even complete breakdowns, with repair costs ranging from thousands to tens of thousands, severely impacting operations.

          Aitejia understands the critical role of pipeline installation and integrates standardized processes throughout. All refrigerant pipeline installations strictly adhere to industry standards. Whenever a pipeline turns horizontally upward, a U-shaped oil return bend is mandatory to ensure the efficient return of lubricating oil to the compressor and prevent accumulation risks. Additionally, our professional installation team optimizes pipeline routing based on the site layout to reduce resistance, pairing with the stable operation characteristics of variable-frequency units to make the system more durable and reliable.

          From production to installation, Aitejia meticulously controls every detail. Our 10,000-square-meter factory directly supplies not only high-quality variable-frequency units but also comprehensive services covering installation, debugging, and after-sales support. We use standardized processes to help you avoid installation pitfalls, ensuring the long-term stable operation of your cold storage and safeguarding your storage security and profits!
