Choosing the right vacuum packaging machine is essential for achieving efficiency, product freshness, and long-term reliability in any food-processing environment. As a manufacturer, we offer both Single Chamber (SC-800) and Double Chamber (DC-800 / DC-800H) vacuum sealers, each designed for different production needs. The Single Chamber Vacuum Sealer is ideal for small to medium operations such as meat shops, grocery stores, restaurants, and start-up packaging businesses. It features a compact stainless-steel body, easy-to-clean flat chamber, optional gas flush, and the advanced PNC-01 control panel for accurate vacuum, seal, and cooling settings. Its simple operation—load, close, vacuum, seal, and reopen—makes it perfect for businesses packing between 100 to 400 items per day. On the other hand, the Double Chamber Vacuum Sealer is built for high-volume, industrial-level production. With two chambers operating alternately, it allows continuous workflow—while one chamber seals, the operator loads the next. This dramatically reduces downtime and boosts output, making it the preferred choice for meat processing plants, seafood factories, and large packaging facilities handling 1,000 to over 10,000 packs daily. The double chamber also includes a heavy-duty structure, large sealing area, flat bed, optional gas flush, and the same intelligent PNC-01 control system found in the single chamber, but optimized for long, continuous shifts. In short, businesses with lighter workloads benefit most from the single chamber’s affordability and compact footprint, while high-volume operations gain maximum speed, efficiency, and productivity from the double chamber design. Depending on your daily output and space, both machines ensure superior sealing quality, extended shelf life, and reliable performance for years.

Which Machine Should the Customer Choose? (Simple Guide)

Choose Single Chamber if:

✔ You pack fewer items per day
✔ You need a compact machine
✔ You want lower initial investment
✔ Your production is batch-based

Choose Double Chamber if:

✔ You need maximum speed
✔ You run continuous production
✔ You need to reduce labor time
✔ You run a meat/seafood factory

In the end, the choice between a single chamber and double chamber vacuum packaging machine comes down to your production goals, pace, and long-term expansion plans. Both machines deliver the same Promarks reliability, sealing consistency, and user-friendly digital control, but each serves a different level of demand. If your business is growing or already operating at high capacity, investing in the double chamber model ensures maximum throughput and efficiency. Meanwhile, smaller operations can confidently rely on the single chamber for everyday packaging needs without sacrificing performance or durability. No matter which model you choose, our machines are engineered to enhance product freshness, improve workflow, and support the future growth of your packaging operation.
