  • The Promarks TC series of vacuum chamber machines were designed with the user in mind. The ideal solution for small processors, retailers, restaurants, and laboratories, these items are affordable enough to be purchased simply as a backup while maintaining superior quality one can rely on during years of heavy use. Primarily used for preserving fresh meats, vacuum packaging has been found to be beneficial in other industries such as pharmaceuticals and electronics, so Promarks products are finding their way into all sorts of industries.

    All of our chamber machines are constructed of a high-quality stainless steel that results in our machines looking better longer. With the option of basic digital or fully programmable controls, you can decide what will best suit your needs. The removable seal bars can be fitted with your choice of a single 6mm wide seal or opt for a thinner seal with hot wire cut-off if that is your preference.

    Busch vacuum pumps are the standard in our industry so we offer them in all of the chamber machines we sell except the TC280. The Italian-made DVP vacuum pump is also an option if you want to control costs. These pumps will maintain reliability while saving you money.We realize that cost consciousness may be very important to you and we try to offer you quality pieces at lower prices whenever possible.

    All Promarks machines are produced to the highest standards. All Promarks machines containing Busch pump are guaranteed to meet the standards of ETL, UL and NSF.
