Temperature control
Temperature control is achieved by a temperature sensor, a controller and a three-way valve. The valve controls flow of hot oil to the tank coils. The valve opens and closes in response to the controller to maintain the stored asphalt at set temperature. Heating is automatically shut off before the asphalt level drops below the tops of the heating coils.

Piping and pipe insulation
Connections for piping are standardized to simplify installation. This is particularly useful when installing multiple tanks. It also makes it easier for you to add new tanks to your facility as it grows. Heatec-fabricated piping is also available, making installation even easier.

Significant savings are possible by insulating asphalt and hot oil piping. For example, one inch of insulation on jacketed 4" asphalt pipe and flanges could save over 21,756 gallons of fuel a year per 100 feet of pipe! 

Standardized piping simplifies installation of multiple or additional tanks. Heatec-fabricated piping makes installation even easier.

This control panel centralizes the operation of actuated valves. It has status lights so you know which valves are open, and which are closed, an important feature for eliminating errors.

Power-actuated valves
Power-actuated valves, such as the ones pictured above, are optional. They allow centralized control of tank fill, supply and return functions. A centralized control panel with status lights reduces the liklihood of operating errors. Moreover, 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.
