Heatec Heli-tank^® Portable Storage Tanks

The Heli-tank^® unit combines a hot oil heater with a heated asphalt storage tank in a portable package. Available in six different sizes with capacities from 10,000 to 35,000 gallons. Numerous options and configurations are available.

Temperature controls are the same as those on vertical tanks. Tank walls are made from A-36 steel plate. Tank heads are also steel, flanged and heavily reinforced with channel stiffeners. Access ladders are provided both inside and outside the tank. Tanks feature the same type of overflow protection described earlier for our
vertical tanks.

Tanks are covered with an aluminum skin and six inches of fiberglass insulation. Standard skin has painted aluminum. Other finishes and colors are optional.

Options

Internal bulkheads are optional. They divide the storage tank into compartments, which can be used for different grades or types of liquid AC, for fuel or for additives. The bulkheads are double-walled and insulated. Various combinations of heating coils and controls can be furnished.

Versions for Polymers

Special versions of the Heli-Tank are available for use with modified asphalt. They heat and store either PMAC (polymer-modified asphalt cement) premixed at asphalt terminals or asphalt cements that incorporate GTR (ground tire rubber) mixed at the hot mix plant. Both versions maintain the PMAC at higher than normal temperatures. Pump and piping systems are oversized because PMAC has a higher viscosity than virgin asphalt.

These special versions use motor-driven mixers to keep material in suspension. The mixers are mounted in the top of the tank and spaced for optimum mixing.
