CEI Vertical Asphalt Storage Tanks are field-proven to provide fast, efficient heating & keep heat loss to an absolute minimum. Their minimal demand on energy consumption helps you avoid unnecessary expenses on your fuel bill. Tanks are usually built to order, and can be configured to meet your specific needs. Many options are available.

Advantages of Vertical Asphalt Tanks

Vertical asphalt tanks minimize the oxidation of asphalt stored inside. That is because the surface area of liquid asphalt that is exposed to air is substantially less inside a vertical tank than in a horizontal tank. 

This control of oxidation is particularly important when storing modified asphalt. Oxidation occurs at a much higher rate as temperatures are increased. Modified asphalt is stored at higher temperatures in order to keep the components from separating. 

Another advantage of a vertical asphalt tank is the minimal ground area it occupies. Vertical tanks have a smaller footprint than horizontal tanks. Four vertical tanks can occupy the same ground space as one horizontal tank.

Mixing Efficiencies

CEI vertical asphalt tanks provide ideal agitation, heating and storage for modified asphalt. The flow patterns and minimal stagnation zones keep the mixture in uniform suspension so the modifier cannot separate. Impellers drive the liquid to the bottom of the tank and allow it to circulate upward and around baffles on the inner wall.

Fast Heating

CEI vertical asphalt tanks have two to three times the amount of heating surface area than is normally provided in other tanks on the market. That means CEI tanks will heat a load of asphalt faster.

CEI puts two layers of highly efficient finned coils in the bottom of vertical tanks 20,000 gallons and larger. When in use, heat transfer oil flows through the coils, heating the contents of the tank.

The time it takes to raise the temperature of asphalt is related to the amount of heating surface. For example, suppose you get a tanker load (6,000 gallons) of asphalt that needs to have its temperature raised only 10 degrees, from 290 to 300° F. 

With 1,152 sq ft of heating surface area, a CEI tank can do the job in just 20 minutes.

Tanks with less heating surface will take longer. And long waits can disrupt your work flow.

Temperature Control

A three-way valve controlled by a temperature sensor allows the hot thermal oil to bypass the coils when the material reaches the set temperature. The sensor causes the valve to open and close as needed to maintain temperature of the liquid asphalt.

More Insulation

At CEI, we fully insulate all surfaces of the tank. More insulation means less heat loss. And when it comes to storing asphalt, losing heat means losing money. That’s because if you’re losing heat, the heating system will be working overtime to compensate. 

A well-insulated tank pays off more in the long run. And CEI asphalt tanks are among the most well-insulated asphalt tanks available.

The top bulkhead has a double-wall that encloses 6” of fiberglass insulation. Outer surfaces of the side walls have 6” fiberglass insulation. 

Unlike other manufacturers, CEI insulates the tank bottom. Its inner surface has 3” foam glass insulation encased in a sealed steel compartment. This feature alone results in a significant reduction in heat loss.

The difference in heat loss between a CEI 30,000 gallon asphalt tank and one of the other tanks on the market is amazing. Theirs has no insulation on the tank bottom, and only 4 inches of insulation on the top and sides. Over the span of 20 years, their tank will lose 2,582,000,000 (2.582 billion) Btu more than the CEI tank. That is equal to 19,517 gallons of No. 2 fuel oil.

Colors & Construction

CEI tanks are made from 1/4” welded steel. The outer skin is aluminum, requiring virtually no maintenance. CEI offers skin in an embossed natural finish, or baked-on enamel finish in black or Astec ivory.

A 20-inch flanged side door near the bottom of the tank provides easy access to the interior. Three external side saddles allow the tank to be transported horizontally.

CEI vertical asphalt tanks are available without mixers. However, CEI does include baffles and a top flanged port so a mixer can be retrofitted later.

Piping & Pipe Insulation

Piping connections are standardized for easy installation. This is particularly useful when installing multiple tanks, or adding more tanks in the future. CEI factory-fabricated asphalt and hot oil piping is available to make installation even easier. 

Insulating asphalt and hot oil piping reduces heating costs. For example, one inch of insulation on jacketed 4” asphalt pipe and flanges could save over 21,756 gallons No. 2 fuel oil per year, per 100 feet of pipe.

Power Actuated Valves

Power Actuated Valves are available optionally for tank fill, supply and return valves. A centralized control panel with status lights reduces the likelihood of operating errors. When the tanks are being filled, the valves are controlled by the plant operator, who is less likely to make errors than truck drivers who may set manually operated valves at the tanks.

Vent Condensers

Vent condensers are available optionally for reducing blue smoke emissions from the tank. Vent condensers capture and reliquefy asphalt fumes, and return them to the tank.

Sampling Valves

Sampling valves are available optionally for taking asphalt samples for laboratory analysis.
