Giải thích
Disposable one-trip cylinders are designed to be used once and must never be refilled or used to store recovered refrigerant; refilling them is illegal and dangerous. Recovered refrigerant goes only into refillable DOT recovery cylinders. When empty and recovered, one-trip cylinders are rendered safe and recycled as scrap.
