Gramatech Series
Commercial & Industrial Machines That Meet UL & NSF Requirements
Chamber type vacuum sealers are among the most versatile machines available for vacuum seal packaging. With the addition of a gas flush system these units can produce results that cannot be matched by other types of vacuum sealer machines. Chamber units also offer the very best vacuum for powder and liquid products that require low oxygen content in the package.
Gramatech offers a complete line of vacuum chamber sealers from commercial quality tabletop and single chamber units to full industrial single chamber sealers and high production double/dual-chamber machines. The entire line of Gramatech vacuum chamber sealers are certified & labeled to meet UL, CSA, and NSF requirements.
Chamber vacuum sealers (sometimes know as Cryovac Sealers) are also among the easiest machines to operate - just close the lid to start the cycle, no footswitch required, and since the seal is produced before the lid opens, you get a uniform seal with no wrinkles every time. From tabletop models to custom machines, IMPAK’s Gramatech Chamber Line has a unit to meet your specific requirements. Compare models in the chart below or contact a chamber vacuum sealer specialist at IMPAK to get advice based on your application.

Benefits of Using a Chamber Vacuum Sealer:
- Greater vacuum percentage (lower oxygen) as compared to a nozzle type sealer
- A larger seal bar (or more than one) will allow the operator to vacuum and seal multiple pouches at the same time resulting in greater productivity
- Little to no operator involvement after the lid has been closed and the cycle has started
- Options for percentage vacuum will allow for partial vacuum if making an object immobile is your goal
- The vacuum pump is built-in so you don't need any additional equipment
Need Something Custom?
Our Intelligent Sealing System is the solution for custom sealing equipment. iS2 chamber sealers offer a higher degree of control, as well as a more convenient touch screen interface, plus the option to store multiple recipes. The iS2 system does not come pre-installed on chamber vacuum sealers; this is an upgrade and begins with a call to our machinery specialists so they can assess your needs and offer a custom system. Generally, we suggest the iS2 system for 520 units and up and do not offer on smaller units unless by unique requirement. The upgrade pricing to the iS2 System will depend on your specific needs.

More About Chamber Sealers
Vacuum chamber sealers are the best choice for a wide variety of products that require a high pressure vacuum to be achieved without the product being crushed, warped or damaged in any way due to the pressure exerted on it by the pouch when a tight vacuum is achieved. Since the entire product and vacuum pouch are processed inside the machines vacuum cavity both the inside and the outside of the package experience the pressure change during the vacuum cycle at the same time. When this is combined with the effect of gas flushing the package before it is sealed a package with ultra-low residual oxygen can be achieved without ever putting the product under damaging pressure. This unique process that can only be achieved with a chamber vacuum sealer is of tremendous benefit to products like cannabis and baked goods as well as many other high value delicate products.
