Directed Flow Channel™ (DFC) Blending SilosColumbian TecTank manufactures bolted and welded DFC gravity blenders in aluminum, stainless steel or factory-coated carbon steel for the plastics market. The DFC blender incorporates both continuous flow and top hole flow principles. Our flow channels and LIFO (last in, first out) tubes result in quick, high-performanceblending with a high single pass blend index. The result is a smoother profile forstored materials and a more homogenous blend. Silos are designed specifically for the flow characteristics of your product which improves the quality of the blend of raw plastic.

Component Installed Tanks™ (CIT)Columbian TecTank will install components as designed and specified by our customers in our welded tanks for chemical and mineral systems. These components may include a slurry tank, bin activators, pumps, metering equipmentand related electrical and plumbing. The Component Installed Tank allows for oneshipment of a completed system, saving you valuable time and money in the field.

Seal Weld™Seal Weld silos from Columbian TecTank combine the wider size selection and siteerection advantages of a bolted tank with the smooth interior benefits of a weldedaluminum tank. The silos are assembled from panels with mechanical fasteners and sealed by welding the internal seams. The welded interior of the product zone is free of ledges. Seal Weld silos may be used to store polymers such as fluff, flakes or pellets.

Flow TestingColumbian TecTank can have your product tested through a proprietary consultant forflow characteristics. We will analyze the consultant’s recommendations and incorporatethem into the design of your silo. Samples of your product will be tested on a state-of-the-art shear tester to predict material flow properties. The results allow us to determine the correct hopper slope and outlet size for functional, reliable mass flow.

CTT ALUMINUM GEODESIC DOME

The CTT dome is a self-supporting aluminum geodesic structure that is fabricated from 6005 A-T6 aluminum and conforms to AWWA StandardD103. The dome surface paneling is designed as a watertight systemunder all design load and temperature conditions. All edges of thealuminum panels are covered, sealed and secured with proprietary inter-locking batten bars to prevent slipping or disengagement under designload and temperature changes. Provisions are made in the design to allowfor thermal expansion of the dome and its parts over a temperature rangeof -40°F (-40°C) to 140°F (60°C).

Structural analysis is performed using stiffness analysis models. Thestructural computer models include the effect of geometry irregularitiessuch as dormer openings and perimeter support members. Drawings andspecifications are completed quickly and many standard size dome partsare kept in stock. The dome’s geometric design allows for fast and efficientconstruction and can be performed on-site by Certified Erectors. Domesare available for newly constructed tanks and can be retrofitted to existingwelded and concrete tanks.

Node PlateNodes are individually engineered to ensure structural integrity and precise fit-up.

PanelsAluminum panels are secured with proprietary gasketed batten bars and sealed node covers.

ManwayManways bolt to the dome strut and are reinforced to provide extra stability.

Other features include:• Structural analysis is

performed using ALGOR finite element analysis.

• Efficient lightweight design.

• Corrosion-resistant aluminum.

• Low maintenance service life.

• Large free span applications.

• Aesthetically and environmentally pleasing.
