The DZ 500 2SB is a double-chamber vacuum sealing machine, giving higher efficiency than a single-chamber model. One swinging lid on two arms moves between the two chambers, and the cabinet carries a front control panel with a vacuum gauge and a digital display and stands on castor wheels. It is rated at 2.3 KW and comes with sealing lengths of 500*10 MM and 600*10 MM, workroom sizes of 620*520*120 MM and 670*540*120 MM, and 1 - 4 cycles per minute. Vacuum packing protects products from oxidation, mildew, corrosion and moisture.
