Versatile Process and Surge Tanks Offer a Variety of Uses
Brock’s polyethylene tanks are ideal for a variety of uses requiring a low-cost, low-capacity tank. Brock offers two tank models: a six-foot (1.8 m) diameter, 3,000-pound (1.4 MT) capacity model and a smaller 53-inch (1.4 m) diameter unit with a 1,500-pound (680 kg) capacity.
Both of these process and surge tanks can be used to hold a wide variety of materials, including free-flowing powders, plastic pellets and some corrosive materials. They offer low fill heights so you can easily place them inside your building. They were also designed to accept a variety of boots available for use with many material handling systems, including Brock’s famous FLEX-AUGER® PLUS Delivery System.
- One-piece body: The one-piece, rotational-molded 60-degree center draw hopper and tank body are seamless to promote smooth material flow.
