Dualpak™ Briquetter

Squeeze more cash from your machining waste

PRAB's Dualpak briquetter by Neff Press increases the value of your metal chips, turnings and swarf by compressing it into solid briquettes. Augers feed chips into a compression chamber. Then two opposing hydraulic cylinders press the metal, squeezing out the cutting fluid or coolant and creating a compact, up to 99 percent dry, briquette.

Briquettes are easy to remelt, transport or store until you can get a better recycling price. You'll also maintain a cleaner, more environmentally friendly shop. The Dualpak is effective at briquetting a wide array of metals, including aluminum, steel, cast iron, copper, brass, titanium, magnesium and others.

Choose from eight models to fit your application needs. Capacities up to 5,000 lb/hr (2 268 kg/hr) are available.
